Wen | Jiashipai fish is not a fish.

In our impression, American car manufacturers don’t seem to be very active in treating real sports cars. Detroit’s Big Three have had many classic muscle cars and small carriages in history, but there are very few sports cars in a narrow sense. Although both Ford GT and Dodge Viper have made a blockbuster, the former has only been revived for two or three years, while the latter has been discontinued for two or three years, and there is still no sign that it will continue to be updated. The historical accumulation can not be compared with Porsche 911, or even as long as Nissan Z series.

But there is also an exception, that is, Chevrolet’s Corvette.

In fact, Corvette is probably the oldest car in the world. The first generation of Corvette appeared as early as 1953, which was better than the other two senior Nameplate— — 9/11 and Mustang were 11 years earlier. Since then, Corvette has produced seven generations without interruption, and the eighth generation will be launched next year.

The 2019 Chevrolet Corvette I test-drive this time is the last model of the 7th generation Corvette(C7). The version is Corvette Stingray Coupe, that is, the power is the basic model of natural inhalation, and the car body is Targa Top created by 911. The carbon fiber hardtop can be disassembled manually, and behind the detachable hardtop is a high roll cage, so it is more like a semi-convertible feeling after opening.

At first glance, you can feel that Corvette is obviously different from Camaro, which belongs to Chevrolet. Corvette’s body is much lower, and the height of the car is only 1234 mm. Although the 6 th generation Camaro has lowered the body in order to get closer to the sports car, the height of the car is still 1350 mm. At the same time, Corvette is much shorter, the length of the car is only 4493mm, which is nearly 300mm less than that of Comalo. The low car height and short body, combined with a large car width (1877mm), give this car a tight feeling of lying on the ground. On the other hand, Corvette’s posture is more backward, which is very similar to the GT model like Ferrari 812 Superfast.

The feeling of driving this car is actually more like a GT than a sports car.

Why do you say that? First of all, although this car has a huge displacement — — Although it is only a V8, it has 6.2 liters, and the maximum horsepower of 461 horses is not low, but this car will not make people feel particularly "sporty" or "fast".

Just looking at the technical parameters of the chassis, you may think that this car has a very good sports foundation.

The first is the layout of front center and rear drive. This layout, in which the engine is placed between the front axle and the driver but driven by the rear wheel, is generally considered as one of the most balanced and maneuverable automobile layouts. This is the layout of Honda S2000. The 7th generation Corvette does have a 50: 50 front and rear axle weight distribution.

The suspension structure does not hold back at all, and its front and rear suspensions are generally considered to be the most suitable double wishbone structure for sports cars. In addition, Corvette’s unique point is that its front and rear suspension damping mechanism is not a coil spring, but a Leaf Spring.

Generally speaking, leaf springs are generally used on trucks because they are harder and have poor shock absorption effect, but they are more rigid and have stronger load-bearing capacity.

However, Corvette’s spring has several major differences: first, it is single-layer rather than multi-layer; Secondly, its material is not steel, but fiber reinforced plastic, which is much lighter than steel plate under the same strength; Finally, it is arranged horizontally rather than vertically, running through the whole axial direction, which can not only reduce vibration in the vertical direction, instead of spiral spring, but also play the role of transverse anti-roll bar. This damping system is considered to greatly reduce unsprung weight, thus improving handling. In fact, this kind of damping structure is also called Corvette Leaf Spring— — Corvette leaf spring.

However, its real sports performance experience is not as beautiful as the technical data said.

In fact, the feeling of driving, the rear of this car is very unstable. First of all, it still shows a certain tail flick in the corner, which makes it feel difficult to control. Secondly, its suspension seems to be a little too soft, its travel is too long, its movement is still slow, and the ups and downs of its body posture will be obvious, and it also lacks confidence because of too little road feeling. Finally, although many lightweight designs are used and the figure is not big, its weight still reaches 1.6 tons because of the excessive displacement of the 6.2-liter engine. Although this figure itself is not too high, it is particularly cumbersome to cooperate with the body that is not stable enough. There is always a feeling of dragging one’s ass around the corner quickly, which is easy to make people panic.

In addition, although its steering virtual position is very small, and the steering wheel has a small width, these are closer to a good steering feel. But on the other hand, its direction is not particularly clear, the steering ratio seems to be a little small, and it will not make people feel particularly easy to control.

And the displacement of 6.2 liters, although it is already the largest displacement among hundreds of cars I have driven, is not fast.

This aspect is the problem of vehicle orientation — — Its sound insulation is good, and the suspension is stable and comfortable at high speed cruising, which leads to its weak sense of speed.

On the other hand, it is the problem of dynamic response — — GM’s 8AT gearbox has a good shift comfort, and there is no obvious setback in fierce driving, but the downshift action is obviously a little slow. It takes one second to think about it when stepping on the accelerator. The exercise mode will be better, but the improvement will be limited.

The only thing that makes the whole car feel passionate enough is the sound of the engine.

In fact, the sound of S2000 and Bosxter are also very good, but compared with this 6.2-liter LT1, it is still slightly inferior. With the advantages of displacement and cylinder number, it is still more detailed and vigorous. What makes people want to stop most is its backfire sound. I don’t know whether it is because of the design of exhaust or something. This car is prone to backfire sound. Just step on the accelerator a little deeper and then take it all away. Sometimes it will sound several times in a row, even when it is ignited. It seems that there is a temper in exquisiteness.

Excluding the sound, just looking at the driving pleasure, it is actually obviously not as good as many cheaper cars, such as Honda S2000, Ford Mustang, BMW 2 Series, and even Subaru Impreza.

So I don’t like this car? Not really.

It’s probably the most comfortable sports car I’ve ever driven for high-speed cruising. That’s why I say it’s more like a smaller GT. Corvette’s chassis is neither as hard as Bosxter nor as dynamic as S2000. This suspension is like a typical American adjustment — — It is soft and the journey is long enough, so it is comfortable enough, and the big ditch will not have excessive impact; The gasket is made of enough materials to look thick. However, because the rebound damping of the suspension is relatively large, the movement is slow, and it feels that it can hold the car body, which is more stable.

And its sound insulation is also quite excellent, especially when driving beyond the legal speed limit in the United States. On the one hand, the rigidity of the car body is good, on the other hand, the 8-speed gearbox is matched with a large-displacement engine with good low torque, and the speed ratio is set low enough. At 130 km/h, the gearbox is in the seventh gear, and the engine is only 1000 rpm. Although the engine is not particularly passionate at high speed, the torque at medium and low speed is quite good. Everyday driving overtaking, lightly stepping on the accelerator, there is enough power without downshifting, and it is very easy to drive.

In addition, its sitting posture is also very comfortable. Although the sitting posture is very low and very backward, it will be more difficult to sit in. But after sitting in it, you can find that the ergonomic design and seat material are comfortable enough, and they are also open and unyielding. I have been driving for 4 hours without any discomfort, which is much more comfortable than Porsche Boxter. The only slot point is that for people who are a little taller, because the roof is too low, the upper edge of the windshield will obviously block the line of sight.

So will I buy this car? It seems unlikely.

The price of this car is not cheap. The starting price of $56,000 in the United States is only 10% cheaper than that of Porsche Bosxter, and after all, the brand, design and interior and exterior workmanship are not as high-end as the latter — — Although the leather and stitching of the interior of American cars are not low-grade, they still have a little flavor. At the same time, although the horsepower is greater, both the power feeling and the control feeling are far behind, and it is not a car that can make people enjoy the feeling of driving too fast.

The place that can make it more like a duck to water is actually Autobahn in Germany. When you really drive 160 km/h or even 200 km/h just to get to your destination faster, this Corvette is relaxed, stable, quiet and comfortable enough, and it can really make the eighth gear useful. But embarrassingly, because of the strict emission, fuel consumption and displacement restrictions in Europe, its price in Europe is very expensive — — It is more than 50% more expensive than Bosxter, which makes it equally uncompetitive.

It’s not easy to say I love you!

Figure | Fish is not a fish

　　Data Map: It is the graduation season for college students, and college graduates from Qingdao, Shandong Province are shooting personalized graduation photo on campus.

　　Reference News Network reported on June 11 that foreign media said that China is about to usher in the "graduation season" for students to graduate collectively. Graduates all want to keep good memories on campus in their own way. The "graduation economy" such as graduation dinners, travel and photo shoots has emerged from time to time and is very hot. Nearly 20% of graduates spend more than 10,000 yuan on graduation.

　　According to the China media report on the website of Lianhe Zaobao on June 8th, the hotels around the school will have a "harvest season" in the graduation season of college students every year, and most students choose the hotels around the school for graduation dinner. In order to attract graduates, some hotels also advertise that "every graduate can book a table with 8.8 discount, and drinks are free".

　　The owner of a restaurant near Northeast Petroleum University said that with the graduation season approaching, the peak of booking graduation dinner is coming. A coffee shop near Heilongjiang Bayi Agricultural University has held a graduation party with the theme of "First Love" since May 14th.

　　A graduate of Qingdao University said that since mid-May, he has had graduation dinners every night and spent a lot of money.

　　He said: "Usually, the living expenses for one month are around 1000 yuan. Now I have calculated in the graduation season, and 3,000 yuan may not be enough."

　　According to the report, in addition to graduation dinners, travel and photo shooting are also an indispensable part of graduates’ good memories in college.

　　Since the end of last month, all kinds of innovative graduation photos have been screened on various social platforms. In addition to the traditional graduation bachelor’s clothes, graduates can rent all kinds of clothes, and many people even seek the help of photography studios to shoot creative graduation photo.

　　A private photographer in Guangxi said that at present, the appointment for taking graduation photos has been arranged until the end of June, and people are still coming to consult, and the original fee has also increased from 100 yuan to 500 yuan.

　　Although Xiao Qin, a graduate of the School of Finance and Economics of Guangxi University, spent a month’s living expenses shooting graduation photos, she thought it was worth it. After all, "Youth never comes again. If you can, why not record your youth?"

　　According to a survey conducted by Qingdao Daily on 40 graduates from China Ocean University, China Shiyou University (East China) and Qingdao University, nearly 20% of the graduates will spend more than 10,000 yuan in graduation season, and most of them will be spent on graduation trips.

　　In addition, in order to impress the interviewer in the job interview, some students spend money to buy interview clothes. Xiao Chen, a graduate of China Ocean University, spent 2,000 yuan on brand suits and leather shoes, and spent a lot of time in making resumes, specifically looking for someone to design resume templates; He spent two or three hundred yuan on printing and copying his resume alone.

　　According to the report, Yuan Jinqiu, from the Department of Political Economy, School of Politics, Guangxi University, analyzed that the emergence of the "graduation economy" conforms to the laws of the market, and many businesses are ingenious in meeting the needs of graduates, which is a very positive economic situation.

　　However, since graduates are not yet financially independent, most of their expenses come from their parents. In this regard, Yuan Jinqiu believes that it is ok for graduates to participate in some job hunting and graduation commemoration activities if conditions permit, but it should be appropriate.

　　Wu Lianhai, consultant of the Mental Health Education and Counseling Center of China Ocean University, agrees with the above view. He said that college students’ consumption in graduation season is a way to express their classmates’ friendship, and some expenses are understandable, but the concept of face and conformity will inevitably contribute to the "graduation economy", so the expenditure in this respect must be measured.

01order

At present, the real estate industry has entered the era of small profits. Real estate regulation and control policies such as "three red lines" and "centralized land reform" have deleveraged real estate and removed its financial attributes, resulting in increased costs, difficult financing, low fault tolerance rate and reduced profit rate to less than 6%.

By benchmarking Country Garden, Vanke and other head real estate companies, this paper makes a detailed and systematic data calculation, analysis and comparison and careful study from four aspects: cost control ideas, cost measurement indicators, specific measures and control conclusions. The specific research and application analysis are as follows:

02The purpose and thinking of cost control

First, the purpose and necessity of cost control:

Through the measures of increasing efficiency, reducing cost and marketing and packaging, the differentiated competition of products can be realized, so as to generate premium benefits, enhance the value and quality of products, further improve the core competitiveness of enterprises, and shape the recognition and brand image of enterprises.

Real estate benefit settlement is dynamic, lagging and long-term. Is a project profitable and how much is it? Only after the development and sales are completed will you know. Therefore, according to the existing project situation, learn the experience of cost control of other real estate to prevent the cost from being wasted or exceeding the standard.

Second, the idea of cost control:

Increase efficiency, reduce cost and enhance product value;

(1) Optimize and reduce structural and functional costs.

(2) Reduce invalid costs.

(3) Increase reasonable and effective costs in sensitive areas that customers pay attention to.

Third, the impact of cost control at each time stage on the overall cost:

1. The stage of land acquisition, planning and design planning affects 70% of the total cost, which belongs to prior control.

2. During the recruitment and construction stage, it affects 25% of the total cost, which belongs to the matter control.

3. The carry-over and settlement stage of completion data affects 5% of the total cost, which belongs to post-event control.

03Cost measurement index

A, the development of total cost index and proportion:

1. Land cost: According to the current 4 million/mu, the plot ratio is 2.0, and the floor cost is about 3090 yuan/m2 (4 million *1.03 (deed tax) /666.67/2), accounting for 40% of the total cost.

For every 1 million mu of land, the cost will increase by about 770 yuan/㎡.

2. Jian ‘an cost: 2,000 yuan/㎡ for high-rise buildings, accounting for 26% of the total cost.

3. Supporting fee: 400 yuan/㎡, accounting for 5% of the total cost.

4. Administrative expenses: 500 yuan/㎡, accounting for 6% of the total cost.

5. Land use tax: 9 yuan/m2 * 50 years /2.0=220 yuan/m2, accounting for 3% of the total cost.

6. Tax: the sales price (8,000 yuan temporarily) *11%=880 yuan/㎡, accounting for 12% of the total cost.

7. Marketing expenses: the sales price (temporarily 8,000 yuan) *2.5%=200 yuan/㎡, accounting for 3% of the total cost.

8. Financial expenses: (2-5, 6, 8) *10%=320 yuan/㎡, accounting for 4% of the total cost.

9. Unforeseen expenses: 100 yuan/㎡, accounting for 1% of the total cost.

10、The above total cost: about 7600 yuan/㎡. Among them, the cost of land and construction and installation accounts for 66%. If the land price is 3 million/mu, the total cost of development is 6,800 yuan/m2.

Second, the construction cost (1-5 controllable) cost index and proportion:

1. Reinforcement: The cost per square meter is about 300 yuan/㎡, accounting for 15% of the construction and installation cost.

2. Commercial concrete: the cost per square meter is about 280 yuan/㎡, accounting for 14% of the construction and installation cost.

3. Exterior wall decoration and thermal insulation: the cost per square meter is about 150 yuan/㎡, accounting for 8% of the construction and installation cost.

4. External window: The cost per square meter is about 100 yuan/㎡, accounting for 5% of the construction and installation cost.

5. Elevator: The cost per square meter is about 45 yuan/㎡, accounting for 2% of the construction and installation cost.

6. Measures cost (including scaffolding, tower crane, formwork, vertical transportation, etc.): The cost per square meter is about 300 yuan/㎡, accounting for 15% of the construction and installation cost.

7. Others: earthwork, fire protection, electricity, water supply and drainage, heating and ventilation, etc.

Third, the height and other cost indicators, the impact on the calculation of Jian ‘an cost

1, the height of the impact on the cost:

(1) For a 17F residential building, for every 0.1m increase in the storey height, the corresponding installation and installation cost will increase by about 2-3% (the steel content will increase by about 1kg/㎡; The concrete content is increased by about 0.01m3/㎡ m2, etc.).

(2) For every 0.1m increase in story height, the construction and installation cost will increase by about 30~50 yuan/㎡ (the higher the material price, the greater the impact).

2. Influence of steel content on cost：

(1), steel cost index:

(1) the average high-rise residential 17F steel content is about 40-58kg/㎡; The steel content of underground garage is about 120-160kg/㎡.

(2) if the purchase price of steel bars is 5000 yuan/ton, it will be about 6000 yuan/ton after charging.

③ The cost index of steel content per square meter of residence is 240-330 yuan/square meter (accounting for 12-17% of Jian ‘an cost).

④ The cost index of the steel content per square meter of the garage is 720-960 yuan/square meter (accounting for 28-37% of the garage construction and installation cost).

(2) Influence of steel content on Jian ‘an cost:

① When the steel content increases by 1kg per square meter, the construction and installation cost will increase by about 6 yuan/㎡ (the higher the steel bar price, the greater the cost will be).

(2) The purchase price of steel bars increases by 1000 yuan/ton, and the construction and installation cost increases by 50 yuan/㎡.

3, including commercial concrete:

(1), including commercial concrete quantity cost index:

(1) the general high-rise residential 17F concrete content is about 0.4-0.5 cubic meters/㎡, and the underground garage concrete content is about 1.5-2.0 cubic meters/㎡.

(2) If the supply price of commercial concrete is 500 yuan/Fang, it will be about 600 yuan/Fang after the fixed fee.

③ Cost index of concrete content per square meter of residence: 240-300 yuan/square meter (accounting for 12-15% of construction and installation cost).

④ The cost index of concrete content per square meter of the garage is: 900-1,200 yuan/square meter (accounting for 35-46% of the garage construction and installation cost).

(2) Influence of commercial concrete content on Jian ‘an cost:

(1) the content of commercial concrete increases by 0.01 cubic meters per square meter, and the construction and installation cost increases by about 6 yuan/㎡ (the higher the material price, the greater the impact on the increased cost). (2) The purchase price of commercial concrete increases by 100 yuan/㎡, and the construction and installation cost increases by 50 yuan/㎡.

4, window to ground ratio:

(1) For general 17F high-rise residential buildings, the window-to-floor ratio is about 0.16-0.31. Based on the calculation of 600 yuan/㎡ of aluminum alloy window with three glasses and two cavities, the floor cost index of external window is about 96-180 yuan/㎡ (accounting for 5-9% of Jian ‘an cost).

(2) For every 0.01 increase in the window-to-ground ratio, the construction and installation cost will increase by about 6 yuan/㎡.

5. Garage and soil covering

(1) For every 0.1m height increase in the underground garage, the reinforcement will be increased by 3-5kg/㎡ and the concrete will be increased by 0.02-0.03m3/㎡； ㎡; Jian ‘an costs about 30-50 yuan/m2.

(2) For every 0.1m increase in the covering soil on the garage roof, the steel content will increase by 1.5-2kg/㎡, and the concrete will increase by 0.015m/㎡ accordingly; Jian ‘an cost increases by about 18-20 yuan/㎡.

6, saleable ratio ()

(1) saleable area: including residential buildings (including bottom businesses) and other saleable areas.

(2) Non-saleable area: parking space, property room, basement, mezzanine, overhead floor, garbage room, police room, kindergarten, equipment room and other supporting areas and gift areas.

(3) Calculated value of head housing enterprises: For every 1% increase in the saleable ratio, the construction cost of Jian ‘an will be saved by about 50 yuan/㎡.

04

Specific measures of cost control

First, reduce invalid costs

1, the concept of invalid cost

Invalid cost is an unstructured and unnecessary cost that does not play an effective role in enhancing product value and promoting marketing, and cannot gain customer recognition and attention. Ineffective cost accounts for about 1-2% of Jian ‘an cost, and the cost per square meter affects 20-30 yuan/㎡.

2. Case measures to reduce invalid costs:

(1) Decorative treatment of air conditioning grille.

The enclosed area inside the air-conditioning grille is the customer’s non-sensitive area, and it is enclosed by the air-conditioning grille, and residents rarely enter it. The practice of real stone paint can be changed to ordinary paint (the current practice of Country Garden).

Taking the project under review as an example, the interior decoration of air-conditioning grille can save the cost: 800 square meters *40 yuan/m2 (price difference) = 32,000 yuan/building.

(2) The garage ceiling is not treated or painted.

The ceiling of the underground garage is a customer’s non-sensitive area, which can’t display well. Moreover, it is blocked by fire fighting, smoke exhaust pipes, bridges and other facilities. Secondly, latex paint or paint is easy to peel off when it is wet for a long time. If the cost of using mildew-proof coating is higher, the surface putty and coating are cancelled, or spray painting treatment is adopted, which will not affect its structural use function.

Take the current project under review as an example, the top of the garage is sprayed with latex paint of 15-18 yuan/㎡, and the area of the garage (including the beam side) is about 25,000 square meters. If it is not treated, the cost will be saved by about 375,000-450,000 yuan; If spray painting treatment is adopted, the cost will be saved by about 120,000-200,000 yuan/phase I garage.

Second, optimize and reduce structural and functional costs

With the soaring land price, the cost of land and construction and installation accounts for more than 66% of the total cost. The product positioning and design scheme in the early stage largely determines the direct profit and loss of the project. Optimize the product line, so that the positioning of the designed products can match the needs of customers. The highest goal is that customers take the initiative to buy products, rather than taking products to find customers.

1. Optimization and cost reduction measures in the planning and design stage (affecting the overall cost by more than 70%):

The main principles are: optimization, benchmarking, quota, adaptation and refinement.

(1) In the planning stage, the most profitable planning layout and product line (the products of high-rise buildings and villas have the highest profitability) are issued through the benefit comparison of various schemes.

(2) Optimize the building shape coefficient: The more complex the building shape, the more concavities and convexities, the larger the external area of the facade, the more complex the structure, and the higher the corresponding cost. Huxing design should be symmetrical and reduce too many concave and convex levels.

(3) Optimizing structural selection and shear wall layout: The structural layout with more short-leg shear walls has a higher impact on the cost.

(4) For the cost index limits such as steel content and commercial concrete content: design internal horizontal comparison, and externally benchmark the head real estate data such as Vanke and Country Garden (the steel content cost index of the same type of drawings in the market can be different to 5-10kg/m2).

(5) Optimize and reduce the window-to-wall ratio: reduce the window area in the north direction and increase the height of the window sill in the south direction (meet the vertical fire-proof spacing and avoid using fire-proof windows). Reducing the window-to-floor ratio is beneficial to energy saving and cost reduction. Door and window frame optimization (reducing the number of window frames).

(6) Reasonably control the type and proportion of the donated area (because the donated area is not saleable, but it is included in the construction and installation cost at the time of settlement), and try to avoid:

1, the proportion of the plane is too high.

2. Large-area nonfunctional overhead floor or negative equipment floor design.

3, a large area of internal transformation, especially a large area of empty patch.

4. Design the stolen area by transforming the facade.

5. Try to use equipment platforms, balconies, bay windows, etc. to give away the area, and control the proportion.

(7) Improve parking efficiency of underground garage: strictly control the pool area of underground parking spaces, and save 30 yuan/㎡ for every unit of parking efficiency.

(8) Increase the saleable ratio:

First, increase the saleable area on the ground and reduce the area of supporting houses and low-profit projects.

The second is to reduce the area of underground storage room and garage. For every 1% increase in the saleable ratio, the cost will be reduced by about 30 yuan/㎡.

(9) Elevation optimization:

(1) Reduce the complex shape of the facade: the building facade should not have too many levels and lines, which is difficult to construct and expensive. Secondly, there are too many lines (especially at the window sill). If too many polystyrene boards are used, it will become a hidden danger of water leakage in the outer window if it expands when heated and contracts when cooled for a long time.

(2) The shape of the roof should be simple: if the sloping roof is adopted, the slope of the sloping roof should be reduced, and the flower pattern and complex lines of the roof should be reduced. The cost sharing of roof modeling of multi-storey residential buildings is large.

(3) lines with a thickness of more than 150 should be poured with concrete, because the heavy rain invades and expands with heat and contracts with cold, which has the potential of falling off.

(9) Control the materials and use parts of the facade: strictly control the use of materials with high cost,

Non-sensitive and minor parts of the owner, such as the second floor above the facade, decorative lines, roof flower racks, equipment floors, etc., shall be made of lower specifications.

(10) garage optimization:

① Control the thickness of the garage cover soil, reduce the thickness of the whole cover soil layer and reduce the cost through local piling slope, and use piling slope to plant larger trees, which has a sense of hierarchy in landscape vision.

② Garage pipeline balance: increase the clear height of the garage lane to prevent cross-operation fighting and pipeline waste.

(3) Set up control centers such as water pump room and fire fighting reasonably, and reduce the length of equipment pipes, wires and cables in the most reasonable and economical position.

4 When the garage fire hydrant is arranged, it should not be arranged at the driver’s door, but should be arranged on the back of the car or on the inside of the post adjacent to the driveway.

(11) Building lobby decoration:

According to different grades of projects, the ceiling on the wall and ground in public areas such as lobby adopts different standard decoration materials to distinguish high and middle grades. Make the just-needed real estate appropriately reduce the cost.

2, material procurement stage optimization, cost reduction measures:

(1) Centralized procurement, with quantity for price.

(2) In exchange for lower material prices through strategic cooperation, based on the future estimated quantity and construction demand.

(3) Guide and cultivate long-term, stable and honest suppliers of materials.

(4) Elevator accounts for about 2% of the construction and installation cost. Customers are more concerned about the safety and quality of elevators. Reducing redundant functions and unnecessary configuration are the main measures to reduce elevator prices.

3. Optimization and cost reduction measures in the construction stage:

(1) Control the quantity and standardization of visas, reduce site changes, and construct in strict accordance with design drawings.

(2) Changes or visas required by the construction unit shall be approved for implementation after repeated confirmation and comparison.

(3) Building construction practices and techniques should be adapted and matched with the current development level of construction technology and the routine practices of engineering construction.

(4) Reduce the construction period reasonably. After the completion and warranty period are up to standard, all costs and expenses will be settled in batches according to the time nodes, and the turnover cycle of funds will be ensured by time span.

4. Optimization and cost reduction measures of garden facilities:

(1) Reduce the proportion of water features. Because of the high cost and maintenance of waterscape, it is easy to become a hidden part of water leakage, and it is not well maintained in the later stage, and deciduous dirt and mosquitoes become a sub-item.

(2) Reduce the number of nonfunctional and expensive landscape sketches such as sculptures.

(3) The proportion of hard scenes shall not exceed 30%. In the landscape cost, the hard landscape area is small, but the cost is high. According to the project quality, control the proportion of hard scene paving and increase the proportion of soft scene. Use real stone paint, tiles or other iterations to replace marble.

(4) The wall of the community is hollowed out, which makes the landscape inside and outside the community coherent and transparent, and reduces the cost.

5. Financial optimization and cost reduction measures:

(1) Accelerate the sales rhythm, quickly turn the funds, reduce the pressure of funds and increase the gross profit.

(2) Tax financial planning, and broaden financing channels.

6. Measures for optimization and cost reduction in the settlement stage:

(1) Combining with the construction technology and practice of the project site, reasonably apply relevant quotas.

(2) Strictly review and check the project visas and contracts, and review and reduce those that are inconsistent with the site or conflict with the quota.

(3) Fine calculation, combined with the construction site, to ensure the authenticity, accuracy and practicality of the calculation.

7. Optimization measures in the marketing stage:

(1) Differentiated pricing of underground parking spaces to improve overall efficiency.

According to the actual scene of the garage, respectively, for the parking spaces with advantages and disadvantages, the price of the dominant parking spaces should be increased, and the price of a few unfavorable parking spaces should be reasonably reduced, which fully reflects the difference of parking spaces’ values, promotes the balanced sales of parking spaces, and is conducive to the elimination of parking spaces and the overall premium.

1. Conditions for price increase of parking spaces:

A. Parking spaces near the elevator or the entrance of the unit.

B, independent parking spaces

C, the distance around the parking space is relatively large.

2. For a few parking spaces in unfavorable positions, appropriately reduce the selling price.

A, mini-car parking spaces, corners or locations where equipment and facilities are extremely obstructed.

B, lane end inconvenient parking spaces.

(2) Add some middle and high-end parking spaces, which will improve the overall benefit of premium.

According to the project grade, on the basis of standard parking spaces (2.4*5.3), a reasonable proportion of medium and large parking spaces (2.6-2.7 in width and 5.3-5.5 in length) will be added.

(3) By giving away a reasonable area or space, we can enhance the higher sales added value, bring more premium, and get rid of chemicals faster, so as to enhance the overall benefit.

1. Optimization of negative first floor space:

The whole negative floor or the south area is presented to the first floor (some lighting windows are added to the negative floor).

Reasons: First, it can bring the first-tier premium and raise the first-tier price; Second: when the underground garage is 3.6 meters, two-story basements must be built below the main building (high-rise), which will design a large number of underground storage rooms, which is not conducive to decontamination. Turn the storage room on the negative floor into a gift space on the negative floor, break it into whole parts and quickly remove it. Third, the storage area of the remaining negative second floor can be designed to be smaller and the total price is lower.

Benefit calculation of two schemes:

A. If the standard floor costs 8000 yuan and the first floor (without yard) costs 7800 yuan, the whole negative floor or the space on the south side will be given as an additional gift to the first floor, and the price of the first floor will be 10800 yuan, and the benefit difference will be 3000 yuan/㎡. The relative selling price of storage room is 2000 yuan/m2, which brings more benefits.

B, if the standard floor costs 8,000 yuan and the first floor (with courtyard) costs 9,800 yuan, the whole negative floor or the space on the south side will be given as an additional gift to the first floor, and the price of the first floor will be 11,800 yuan, and the benefit difference will be 0 yuan/㎡. Basically, it is almost the same as selling the storage room at a price of 2000 yuan/m 2. Double added value can’t bring more profit growth, but it will solve the problem of slow storage room.

2. Optimization of negative two-story space:

The south area of the negative second floor (which has a large space facing the living room and bedroom) is used as a parking garage to increase the price. The premium capacity of the parking garage is much higher than that of the parking space, and it is fast and limited, so customers have priority to buy it.

Third, increase reasonable and effective costs in sensitive areas that customers are concerned about.

In the sensitive parts or areas that customers pay attention to, increase reasonable effective costs, improve quality, and let customers get the best value for money, thus generating a premium and increasing benefits. In the period of high housing prices and high costs, it is not suitable for price wars. By improving quality, selling price and profit, the brand effect can be expanded, and brand promotion and secondary premium can be given by word-of-mouth effect.

1. Sensitive areas of customer concern:

(1) According to the streamline of returning home: waiting hall, lobby, garage lobby and garage entrance.

(2) According to the architectural visual concerns: community gate, unit door bucket, first floor and facade.

(3) According to the landscape visual concerns: main entrance, core landscape axis and nodes, unit entrance, group landscape nodes, and residential fence.

2, in the home streamline, increase the reasonable and effective cost:

(1) The waiting hall, the lobby on the first floor and the garage are connected to the indoor lobby, and sensitive parts are paid attention to at the first level for customers. According to the grade of the project, simple and refined decoration is adopted to improve the quality of entering the home and create a sense of belonging at home.

(2) The fire hydrant and other equipment and facilities in the waiting hall are constructed with concealed fittings to avoid inconvenient access for customers.

(3) The lines at the entrance of the garage and the gate of the community are more thick, and the ceiling should not be made of glass. The slope at the entrance should be raised appropriately, and the entrance should be illuminated by lights.

3, building facade, increase the reasonable and effective cost:

(1) Lines and shapes are added to the 1-2 floor base and unit door bucket area of the building, which enriches the details and makes it more heavy.

(2) The color matching of the facade adopts color matching to replace the division of lines or shapes (high cost). Multi-storey horizontal different color surfaces make the building more thick; High-rise buildings adopt different vertical colors, which makes the building stand tall and straight.

4, landscape, increase the effective cost.

Excellent core landscape brings high-quality on-site experience to customers and directly raises the house price.

(1) First-class landscape areas such as main entrance, core landscape axis and nodes, unit entrance, and group landscape nodes should be built with emphasis.

(2) The children’s playground is set in an open space, and the surrounding vision is wide.

(3) A fitness track is added in the secondary landscape zone (semi-private) of the community, and cultural tips are added around the track to distinguish areas, which increases the identification and interest of the space and improves the humanistic quality of the project.

(4) The right corner of the road shall be rounded to prevent trampling.

4. In terms of intelligence, increase the effective cost.

A fully intelligent identification system for the owner is composed of face recognition of the gate, face recognition of the unit door, fingerprint lock of the entrance password, license plate number recognition system of the basement and automatic induction gate, which is convenient for the owner to enter and exit without keys and Bluetooth cards.

5, garage and other supporting aspects, increase the effective cost

(1) The garage driveway is the customer’s concern area, and it is made of toughened or grinded stone floor, while others are made of solidified wear-resistant floor (epoxy floor is not recommended, because the garage is wet and not wear-resistant, and after 1-3 years, there will be problems of sanding and falling off in different degrees, which will reduce the quality).

(2) Lane lighting design, lane lights and lane guide arrows are aligned up and down, which broadens the vision of two-way lanes, makes driving light feel more comfortable and ensures driving safety.

(3) The large-scale garage is divided into zones and colors, which is easy to identify and provides a simple sense of orientation.

(4) The garage is equipped with a zebra crossing on the sidewalk to distinguish the traffic flow and pedestrian line in the underground garage, which not only guides the owner to cross the driveway safely, but also plays a role in warning the vehicles driving in the basement to speed limit.

(4) Establish a model first and a quantity exhibition area, and stimulate customers’ purchasing desire and transaction rate through case experience.

(5) Set some smart WIFI, hidden trash cans, and some direct drinking water in the outdoor public activity area, so that customers can experience differentiated services and excellent living experience with less cost and attention to details, and improve quality.

Item 4: The conclusion of cost control:

All departments and stages refine the cost control, so as to prevent in advance, control in the process and analyze afterwards, forming a closed-loop and virtuous circle of the whole process.

First, improve the cost consciousness of all staff, establish the overall situation consciousness, and fully realize the close relationship between cost and income: reducing cost means increasing efficiency.

Second, all relevant departments should cooperate with each other, strengthen cooperation, establish a whole-process and full-staff cost control system, and dig deep into cost optimization and reduction measures:

1. Plan, design, optimize and innovate iterative products.

2, construction management to ensure quality.

3. Centralized strategic procurement of materials.

4. Marketing packaging: explore the core value and increase the premium rate.

5, financial control system control.

7. The Legal Department should guard against risks.

8, the completion of the settlement strictly according to the facts.

6. The feedback data of property customer service complaints are used as experience books to form a closed loop.

The real estate competition has entered the stage of high-quality and high-value differentiated competition. At present, real estate developers should seize the challenges and opportunities, enhance the concept of value promotion and cost control, take effective management and control measures, and do fine cost management with the craftsman mentality of "wringing the last drop of water on the towel" to enhance product value and create value for customers, so as to enhance the value of products and the core competitiveness of enterprises, so as to achieve sustainable and healthy development.

Shangqiu-Hangzhou Railway is the second channel project of East China North-South Railway in the Medium-and Long-term Railway Network Planning of Anhui Province, and it is listed in the National Twelfth Five-Year Comprehensive Transportation System Planning. The project starts in Shangqiu, Henan Province, passes through Bozhou, Fuyang, Huainan, Hefei, Wuhu and Xuancheng in Anhui Province, and Huzhou in Zhejiang Province to Hangzhou. The main line is 795 kilometers long, with a design speed of 350 kilometers per hour and a total investment of about 96 billion yuan.

(2) Overview of Bozhou section. The Shang-He-Hang Railway is 67 kilometers long in Bozhou, with three passenger stations, namely Bozhou South Station, Lumiao Station and Gucheng Station. The two major node projects are the Guohe Bridge and Gucheng Bridge.

In order to give full play to the driving role of high-speed rail in urban economy, our city actively strives for the adjustment of high-speed railway station from Bozhou Station to Bozhou South Station, and the scale of the station building is 15,000 square meters.

In order to realize the connection between Bobang Intercity and Beijing-Shanghai High-speed Railway and Shanghe-Hangzhou Railway, with the efforts of our city, the railway head office agreed to reserve the conditions of Bobang Intercity Access in Bozhou South Station in the preliminary design reply of Shanghe-Hangzhou Railway: the arrangement scheme of Shanghe-Hangzhou Yard and Bobang Yard shall be adopted, and the planning and design shall be based on three sets of seven lines in Shanghe-Hangzhou Yard and two sets of three lines in Bobang Yard; Recently, there are 6 arrival and departure lines (including main lines) and 2 platforms in Shanghe Hangchang Station.

(3) Project progress. Our city has established an integrated promotion mechanism in the urban area, and unified all relevant functional departments in the urban area under the leadership of the local work headquarters in Bozhou section of the Shanghe-Hangzhou Railway, which has reduced intermediate links and improved the promotion efficiency from the system setting. Under the guarantee of working mechanism, the construction of our city is progressing smoothly. Since the construction units of China Railway 21st Bureau, Electrification Bureau and 18th Bureau entered the site in December 2015, the project progress has always ranked first in the province. As of June 25th, the pier construction of Bozhou section of Shanghe-Hangzhou Railway has been fully completed. Subgrade ancillary works have been built.

The building of Bozhou South Station was built by China Railway Beijing Bureau and entered the site on April 20th.

In order to realize the consistency of architectural style and the synchronization of construction between Bozhou station square and station building, our city took the lead in carrying out the combined bidding for the planning scheme design of station square (government) and station building (railway), which was praised by the railway corporation. At present, the square in front of Bozhou South Station was built by China Construction First Bureau, and the foundation stone was laid on April 18th. The preliminary construction section of Bobang intercity railway (station building and tie line project) has started construction, and the pile foundation construction of the cross-business Hehang Bridge has been completed, and the pier construction is currently underway.

(4) The next step. Our office connects five construction units (China Railway 21st Bureau, Electrification Bureau and 18th Bureau), station building (China Railway Beijing Bureau) and plaza (China Railway 1st Bureau) every week to optimize the construction environment, coordinate and solve problems, fully promote the construction of Shanghai-Hangzhou high-speed railway, and ensure the realization of the goal and task of keeping the progress among the best in the province.

3. Preliminary work of Bobang-Huaifu intercity railway project.

In order to improve the traffic location advantage in northern Anhui and improve the layout of railway network, the Provincial Railway Office has carried out the compilation and approval of the Inter-city Railway Network Planning in northern Anhui. At present, the text of the Plan has been completed; In May 2017, the environmental impact report of the Plan was approved by the Ministry of Environmental Protection; At the end of 2017, the Plan was revised according to national requirements and reported again. The Plan includes the inter-city railways of Huai-Su-Fu and Bo-Bang.

The preliminary work of the inter-city railway project in northern Anhui Province was promoted by Anhui Investment Group. At present, the first draft of the Feasibility Study Report on the New Huaisu-Bengbo Express Railway has been compiled by China Railway Shanghai Design Institute. After the "North Anhui Intercity Railway Network Planning" is approved by the state, the provincial investment group will take the lead in joint venture with the cities to promote the project construction in accordance with the relevant policies of the Anhui provincial government’s upcoming intercity railway development opinions (extracting construction funds from land transfer fees, setting up a compensation mechanism, and comprehensive land development, etc.).

According to the convergence, in accordance with the deployment of the state to strictly control financial risks, the National Development and Reform Commission has successively issued policy requirements for urban rail transit and intercity railways. All provinces and cities must establish a fund-raising and loss-making mechanism, strictly control project loans, and suspend the approval of relevant plans in 2018. In the next step, we will put forward implementation suggestions based on the development opinions of provincial intercity railways and the development needs and stages of our city, and report to the municipal government to study and determine the construction timing of the Bo-Bang intercity railway, and carry out related work such as raising construction funds.

　　CCTV News:The annual year-end consumption peak season has arrived. In the consumption peak season of 2023, the reporter saw that consumer demand is more subdivided and vertical, consumption is more decentralized and personalized, and intelligent, experiential and high-quality products are exploding. From the industrial point of view, the diversity of consumer demand also promotes the trend of personalized production and flexible customization on the supply side.

　　Under the increasingly diversified consumer demand, refined home appliances are more sought after by consumers. The data of the e-commerce platform shows that the sales of smart home products that can enhance the sense of home life experience have increased significantly. Among them, the turnover of intelligent sensing faucets, intelligent door locks, intelligent lifting tables and other products all increased by more than 100% compared with the same period in 2022.

　　Healthy consumption has also become a kind of consumer goods with high willingness of consumers. According to the data of the platform, in the "Double Eleven" in 2023, the outdoor sports industry showed explosive growth, and the sales of cycling, skiing and out shoes clothing products increased by 300% year-on-year.

　　On the major e-commerce platforms, the reporter noticed that domestic brands are highly sought after by consumers. According to the data of China International Electronic Commerce Center Research Institute, in this peak consumption season, among the top 20 brands in online retail sales, domestic brands occupy 11 seats.

　　While the consumption trend changes, it is also promoting the transformation of the industry. Li Mingtao said that relying on the support of online big data, enterprises can more clearly understand the needs of consumers, and thus rely on personalized production and flexible customization to accurately match related needs.

　　Promote featured products and adopt various operation methods to cope with the sales peak.

　　The annual year-end consumption season is also an important node for enterprises to sprint annual sales. At present, local enterprises are actively enriching their means of operation and vigorously promoting local specialty products.

　　In Hanzhong, Shaanxi Province, the local digital economy industrial park jointly settled in enterprises, and launched online live broadcast and other activities for the first time to introduce local agricultural special products to consumers.

　　This company, located in Jiangmen, Guangdong Province, has developed a series of snack foods and organic foods based on local specialties such as Xinhui dried tangerine peel and Taishan rice. The person in charge of the company predicts that the sales volume of the company’s products will rise sharply this consumption season. In order to cope with the sales peak, the company made sufficient preparations in advance.

　　The new express delivery mode allows goods to reach consumers faster.

　　During the peak consumption season every year, the express delivery volume will explode. The growth of express delivery reflects the vigorous vitality of China’s consumer market. At the same time, how can consumers get the goods they ordered faster?

　　At a courier service outlet in Mianzhu City, Sichuan Province, the staff are busy scanning the code for express parcels, putting them on the shelves, and three shelves are filled with parcels stored on behalf of others.

　　It is understood that during the end-of-year consumption peak season in 2023, major express delivery companies in Mianzhu have increased their investment, and tried their best to reduce the phenomenon of express delivery squeeze and delay by increasing operating venues, adding automation equipment, expanding transportation capacity and increasing manpower.

　　In Jinhua, Zhejiang Province, relying on the mode of "integration of passenger and freight", express delivery can take the bus to the village, so that more rural people can enjoy the same timely delivery service as in the city, which greatly improves the timeliness of express delivery. Wu Chengrong, a villager in Shenfan Township, Jinhua City, just got his first package of this year’s "Double Eleven" a few days ago.

　　In addition, the local area also adopts the new logistics mode of "regional co-distribution", relying on the postal network, integrating the first-class distribution resources of each express brand village and town, and realizing the automatic sorting of all express brands in the same line. Postal couriers can complete the express transportation and delivery work of different express delivery companies, which greatly relieves the logistics pressure of the "last mile" in remote areas.

　　According to the monitoring data of the State Post Bureau, November 1 — On November 4th, the whole network collected 2.027 billion pieces of express delivery, up 16.1% year-on-year and 31.0% quarter-on-quarter, reaching a record high.

Google’s strongest AI model, which has attracted much attention and is considered by the industry to be the most likely to beat GPT-4, has finally appeared!

On December 6th, US Western Time, Google CEO Sundar Pichai and DeepMind Director Demis Hassabis jointly announced the official launch of Gemini 1.0 in official website.

Gemini is jointly created by several Alphabet teams such as Google Research and DeepMind. As a new powerful multi-modal artificial intelligence model, it can induce, understand, operate and combine different types of information. It can not only process text, images, video and audio, but also complete complex tasks in mathematics, physics and other scientific fields, and can understand and generate high-quality codes in various programming languages.

Pichai described Gemini as "our largest and most powerful AI model to date" and said that it has shown the most advanced performance in many leading benchmarks. "The first generation of Gemini 1.0 was optimized for different sizes, namely: Ultra, Pro and Nano. These are the first models to enter the Gemini era and the first realization of our vision when we established Google DeepMind earlier this year. "

At the Google I/O conference in May this year, Pichai spoiled the news that Google was developing Gemini. It is described as the "Next Generation Multi-modal Intelligent Network", which is designed for API integration. It is said that it has trillions of parameters like GPT-4, but its computing power is five times that of GPT-4, and it can perform more complex and diverse tasks.

To this end, Google also merged its two strongest artificial intelligence laboratories: Google Brain and DeepMind, led by Demis Hassabis, the former CEO of DeepMind, and invested hundreds of millions of dollars in research and development of Gemini.

Even sergey brin, the co-founder of Google, who has resigned for four years, has returned to the office of Mountain View in Silicon Valley to participate in the Gemini decision-making and join the LLM scuffle.

But just last week, The Information quoted people familiar with the matter as saying that Pichai recently silently canceled a series of Gemini public appearances that should have been held in California, new york and Washington, D.C., because it was found to be "unreliable in handling some non-English queries", which cast a gray color on the product launch process.

Perhaps to consolidate market confidence, early this morning, Gemini 1.0 suddenly made its grand debut, appearing in the public’s field of vision and quickly occupying the front pages of major scientific and technological media.

So, what is the strongest artificial intelligence model that Google is betting on the whole army?

Hassabis, head of DeepMind, called Gemini their most flexible model, which can run efficiently on all kinds of devices from data centers to mobile devices.

In order to achieve this extensibility, Gemini 1.0 has designed three versions with different functions and sizes:

Gemini Nano —The most efficient model on the end-side equipment. Designed for smart phones, it can perform efficient AI processing tasks without connecting to an external server. Now it has been integrated into Pixel 8 Pro, which can support the function of "summarizing text" in recording applications and the function of "intelligent reply" in Gboard. Starting with WhatsApp, it will be extended to more applications next year.

Gemini Pro —The best model for various tasks running in Google data center. Support the latest version of the AI chat robot Bard from today. It can respond quickly and understand complex queries, which is the biggest upgrade since Bard was introduced. At present, it provides English services to more than 170 countries and regions, and plans to support new languages and regions in the coming months, and apply them to more Google products such as search, advertising, Chrome and Duet AI.

Gemini Ultra -The largest and most powerful model, dedicated to highly complex tasks, will be provided to developers and enterprise customers early next year after completing the current testing phase. At that time, an updated version of Bard Advanced based on Gemini Ultra will be launched.

In terms of model architecture, Gemini still uses Transformer architecture, adopts an efficient attention mechanism, and supports the context length of 32k.

Google confidently said that after rigorous testing and performance evaluation of the Gemini model, from natural image, audio and video understanding to mathematical reasoning,Among the 32 academic benchmarks widely used in the research and development of large-scale language models, the performance of Gemini Ultra has exceeded the most advanced level represented by ChatGPT at present.. Before the release of Gemini, Google conducted a series of tests to evaluate it with standard industry indicators.

In the MMLU test, the score rate of Gemini Ultra is 90.0%, which is higher than that of GPT-4 (86.4%), making it the first model to surpass the performance of human experts. The MMLU test covers 57 subjects, including mathematics, physics, history, law, medicine and ethics, and aims to evaluate the model’s understanding and problem-solving ability in the global knowledge field.

In Reasoning, Math and Code, except HellaSwag, which lags behind GPT-4 by 87.8%, others include challenging math problems such as multi-step reasoning, algebra/geometry/pre-calculus and so on.

In terms of multimodal capability, Gemini Ultra achieved a SOTA score of 59.4% in the new MMMU benchmark test, which exceeded the 56.8% of the multimodal version GPT-4V of OpenAI. This benchmark test spans many different fields and requires precise reasoning for many tasks.

In the image benchmark test, even without the assistance of Object Character Recognition (OCR) system, the performance of Gemini Ultra is better than all previous models only by analyzing pixel information. In audio testing, the scores of automatic speech recognition and automatic speech translation of Gemini are higher than those of Whisper system connected to GPT-4.

Hassabis said that this highlights the superiority of Gemini’s native multimodal. Up to now, the usual way to create multi-modal models is to train individual components of different modes independently, and then splice them together to try to simulate some functions.

Although such models can sometimes effectively perform specific tasks such as describing pictures, they often perform poorly in more conceptual and complex reasoning.

Gemini was originally designed in a native multi-modal way, and was pre-trained in different modes from the beginning using TPUs v4 and v5e chips designed by Google.. Then it is fine-tuned with more additional multimodal data to improve its performance.

This method enables Gemini to understand and reason all kinds of input content more naturally in the initial stage, and its ability in almost all fields has reached an unprecedented advanced level.

First of all, Gemini has complex multi-modal reasoning ability, which can help to understand complex written and visual information and discover indistinguishable knowledge content in massive data.

For example, it is instructed to filter irrelevant papers through the natural language prompt, or extract key data through reading. With a lunch break, Gemini can help you extract 250 document points from 200,000 papers, and further transform the data into any required chart form. This will greatly help to achieve innovative breakthroughs in science, finance and other fields at a digital speed.

The trained Gemini can obviously recognize and understand text, image and audio data at the same time, better understand subtle information and answer questions related to complex topics. This makes it especially good at explaining reasoning in subjects such as mathematics and physics. In the example, the staff showed that Gemini can check handwriting physical mistakes and explain the correct way.

In order to show the multimodal capabilities of Gemini more intuitively, Brother Chai released a video in X, saying that "the best way to understand the amazing potential capabilities of Gemini is to look at their practical applications".

In the video, Gemini taught the staff the pronunciation of "duck" in Mandarin according to the instructions, and also explained the Chinese tone.

The staff also gave Gemini a demonstration of interaction only in Chinese. By asking about the indoor light in a picture, Gemini is asked to give the orientation of the apartment in use. Gemini answers in Chinese and guesses that the room faces south. Circle a plant in the photo and ask what kind of lighting it needs. gemini then explains the plant species and lighting requirements. The whole process is as smooth as the mother tongue, which shows that Gemini is outstanding in multilingual environment, which is no less than GPT-4.

In addition, Gemini can understand, interpret and generate high-quality codes of the most popular programming languages in the world, such as Python, Java, C++ and Go. The ability to achieve cross-language work and handle complex information makes it one of the world’s leading basic coding models, helping programmers to use the powerful AI model as a collaborative tool to design applications.

For developers, starting from December 13th, Gemini Pro can be obtained through the Gemini API in Google AI Studio or Google Cloud Vertex AI. Android developers can also use Gemini Nano, the most efficient model for end-to-end tasks, through AICore.

Looking back on the development of Google’s big model all the way, compared with the continuous and rapid update of OpenAI’s "Wang Fried", Microsoft always seems to be one step behind when it integrates various AI functions of GPT into core products and pushes them to customers. When Bard, a chat robot, was released in February this year, it got off to a bad start, and the market value evaporated by 100 billion dollars overnight with a factual error. Benchmarking Microsoft Copilot’s Duet AI work suite, the market response was moderate, and the financial performance of cloud services also lost to Microsoft.

Especially after the internal friction caused by the reorganization of Brain and DeepMind teams and the loss of senior talents to OpenAI, Google’s AI battle is even more exhausted.

However, this is, after all, an AI pioneer who contributed to Transformer’s pioneering masterpiece Attention is all you need and the landmark artificial intelligence program AlphaGo, and inspired the subsequent development of many large models including ChatGPT. No matter from the technical genes, training data, capital and infrastructure, it should have one of the best strengths.

The release of Gemini is regarded by Google as the most critical technological innovation in the past decade. Can it make Google rally, beat OpenAI and regain the throne of the big model stadium?

Will the AI competition pattern be reshaped after Genmini Ultra comes out next year?

And, has everyone tried the new Google Bard? How do you feel?
