On August 28th, Shang Tang Group released the semi-annual report for 2023, achieving an operating income of 1.433 billion yuan in the first half of the year, up 1.3% year-on-year; The net loss narrowed by 2% compared with the same period of last year, and the adjusted net loss narrowed by 6.7%.

The financial report shows that the Group’s revenue related to generative AI has achieved a strong growth of three digits thanks to the release of the "day-by-day" big model system during the reporting period, and the generative AI product series such as "Consultation SenseChat", "Second Picture SenseMirage" and "Shadow SenseAvatar". According to the latest news, Shang Tang’s "growing day by day" big model has passed the Interim Measures for the Management of Generative Artificial Intelligence Services for the record, and Shang Tang’s "Consultation SenseChat" has been officially opened to the whole society.

Shang Tang said that while increasing investment in R&D of large-scale models, the Group still adhered to the operating goal of continuously reducing losses. Combined with the management requirements of cost reduction implemented since 2022, its AI commercialization efficiency improved, and the current operating cost decreased by 6.5% year-on-year.

Shang Tang’s capital reserve is still sufficient. By the end of the reporting period, Shang Tang held a total of 14.82 billion yuan in bank deposits, cash in hand, structured deposits, bonds and other fixed-income products.

The iteration of large-scale model technology is accelerated to consolidate the core competitiveness of AI.

Since the end of 2022, the generative AI model has been on the rise, and the world’s major technology giants are rushing into the big model track, intending to get a slice of this promising market.

IDC predicts that in 2026, the AI big model market in China will reach 21.1 billion US dollars, and nearly 50% of the terminal devices in China market will have AI engine technology.

In April, 2023, Shang Tang’s "Consultation SenseChat1.0" was released, which is one of the earliest chat robot products based on the large language model with hundreds of billions of parameters in China.Only two months later, Shang Tang, together with a number of top domestic scientific research institutions, released the first basic model InternLM with comprehensive performance exceeding GPT-3.5-turbo in China. On this basis, "Consultation" quickly iterated to version 2.0.

In August, the new model InternLM-123B completed the training, and ranked second in the world in terms of test scores on a total of 300,000 questions in 51 well-known evaluation sets around the world.For example, in five evaluation sets on reading comprehension, the scores of InternLM-123B are all higher than those of GPT-3.5-turbo and the LLaMA2-70B model newly released by Meta, and the scores of individual test sets differ by nearly 20 points.

It is reported that InternLM-123B focuses on upgrading the code interpreter and plug-in calling ability. python interpreter, API calling and search can be used to solve complex tasks and flexibly build AI agent applications. Due to the remarkable improvement of the new model, it is expected that "Consultation SenseChat" will be upgraded to version 3.0 in September.

In addition to the big language model, Shang Tang is also committed to training the world’s top three models of Wensheng Map. As early as January, Shang Tang’s second painting 1.0 started the internal test, and a second-dimensional picture can be generated by inputting prompts; In April, the second painting was upgraded to 2.0 and officially released; In July, version 3.0 of Seconds Painting adopted a brand-new generation model architecture, which can realize professional photography-level picture detail description, and its core algorithm surpassed Google’s Imagen and OpenAI’s DALL·E2 on COCObenchmark.

With the iteration of Shang Tang’s second painting from 1.0 to 3.0, its model parameters increased from the initial 800 million to 7 billion. Version 4.0 is expected to be launched in the third quarter of 2023, and new aesthetic system support will be introduced.

The iteration speed of Shang Tang AI model is extraordinary, which is due to the support of the computing infrastructure behind it. Since 2023, in order to maintain its core competitiveness, Shang Tang has continuously upgraded SenseCore, an intelligent computing infrastructure. The number of online GPUs has increased from 27,000 at the end of March 2023 to about 30,000 recently, and the computing power scale has increased by 20% to 6ExaFLOPS.

Since 2023, more than 1,000 large models with parameters ranging from billions to hundreds of billions have been trained on Shang Tang AI equipment, which has achieved technological iteration leading the industry and supported dozens of generative AI applications.

It should be said that the maturity of any AI technology is by no means achieved overnight. Behind Shang Tang’s big model is the "miracle" of deep learning algorithm, computing power improvement and data accumulation, and deep cultivation for several years.

According to the AI Big Model Market Research Report (2023) published by Jost Sullivan, Shang Tang ranks first in China in terms of comprehensive competitiveness in product technology, strategic vision and ecological opening-up construction.

Release the commercial potential of big model and accelerate the optimization of business structure

When people talk about the big AI model, most of the time they are feeling the impact and subversion it brings to all walks of life, but few people think that the commercial landing of the big model will come so quickly.

The industry has been growing crazily for half a year, and it has completed the transformation from "Hundred Models Battle" when running into the market to thinking about putting technology into practice. Industry analysts believe that with the rise of basic model and tool layer, the cost and difficulty of building applications will be greatly reduced. For application developers, all downstream applications are worth reconstructing.

The observation of AI trend in the era of big model points out that vertical domain application is the main battlefield of big model. With the rapid development of generative AI technology, it has spawned brand-new commercial value in many fields. Although these models are in the early stage of expansion, they also show excellent capabilities. Like other disruptive technologies, this change will develop slowly at first, and then accelerate rapidly.

A ready-made case is that in Shang Tang’s interim report, this change is gradually emerging.

In the first half of 2023, Shang Tang’s revenue related to generative AI recorded a year-on-year growth of 670.4%, and its contribution to the Group’s business increased rapidly from 10.4% in 2022 to 20.3%.Large-scale model has become an important driving force to upgrade the business of Shang Tang.

It is understood that Shang Tang released a series of generative AI products in April, which is one of the earliest enterprises in China to release related products, including Consultation, Secondhand Painting, Ruying, Qiongyu and Gewu, respectively corresponding to the five mainstream generative AI application landing scenarios: natural language interaction, AI Wen Sheng Tu, digital people, 3D big scene reconstruction and 3D small object generation.

The landing and maturity of AI big model not only accelerates the transformation and optimization of Shang Tang’s own business structure, but also shows the potential of more business application scenarios.

Reflected in the business level, at present, Shang Tang’s main businesses are divided into four major sectors, namely, smart business, smart life, smart cars and smart cities. During the reporting period, Shang Tang actively promoted the commercial application of AI technology and helped customers to quickly iterate new products based on large models, with remarkable results.

Among them,Driven by the big AI model, the revenue of the smart business sector increased by 50.2% year-on-year to 854 million yuan, the revenue proportion increased by 19.4 percentage points to 59.6%, the number of service customers reached 481, and the revenue of single customers increased by 59.9%.For example, in cooperation with domestic head insurance companies, Shang Tang provided cross-validation of crop underwriting data based on AI remote sensing model, which helped to improve the risk assessment and claims service system. Compared with the traditional manual identification scheme, the efficiency was improved by 60 times.

The tentacles of the smart life business extend to the C-end. In cooperation with customers in different fields such as e-commerce, traditional media and community platforms, Shang Tang’s AI products such as consultation, second painting, shadow and grid objects all come in handy. From digital life to high-precision 3D object modeling ability, Shang Tang’s technical strength can be intuitively presented to C-end users. During the reporting period, the revenue of this business increased by 6.7% year-on-year to 312 million yuan, the proportion of revenue increased to 21.8%, and the number of customers increased by 47.5% year-on-year.

Besides,The revenues of smart cities and smart cars are 184 million yuan and 84 million yuan respectively.Among them, the mass production business of Jueying achieved a year-on-year growth of 573%, and the number of mass production deliveries reached 390,000 vehicles, driving the gross profit of bicycles to increase by 29%. In terms of intelligent experience, Shang Tang built an intelligent assistant in the cabin based on "Consultation" and launched a number of interactive products in Chinese in the cabin. In the first half of the year, the number of smart car customers of the company increased by 70% year-on-year to 34. With the continuous transformation of its cutting-edge technology, the business income is expected to show a rapid growth trend.

Guolian Securities Research Report believes that the AI big model opens the second growth curve in Shang Tang, Shang Tang is in the leading position in R&D investment and business scale, and it is also the first manufacturer in China to lay out the AI big model. The company has accumulated rich technology and application experience in the AI field, which is expected to take the lead in the AI 2.0 era and promote the further growth of the company’s performance.

It is worth mentioning that,Previously, Shang Tang United many countries.bestThe model InternLM-7B, with a parameter of 7 billion, released by scientific research institutions, has opened some of its training data, training codes and basic model weights to academia and industry for free, and supports commercialization.

On August 31st, Shang Tang expanded its opening authority again, and announced that the large-scale model application "Consultation SenseChat" will be fully opened to users from now on, which is one of the first domestic large-scale models successfully filed and approved to go online.

1905 movie network news On April 12th, the film Hot Search exposed the concept poster and officially announced the lineup. The film is directed by, starring, and tells the story of an explosive article by Chen Miao, editor-in-chief of the media, which accidentally involves a criminal case. Xin Yukun, the director of the high-profile crime film, partnered with Zhou Dongyu for the first time, which is really exciting.

The newly released concept poster is also fascinating. The poster is covered with endless digital barcodes. Zhou Dongyu’s eyes seem to be staring, but it also reveals a trace of helplessness. Under the shadow of her side face is the figure of Justin, just a twist, but people can’t help but get nervous. What kind of relationship they have and what they will experience are all curious.

Director Xin Yukun cooperated with Zhou Dongyu for the first time.

Focus on the just battle of the network

Director Xin Yukun is praised by many movie fans as one of the directors who can shoot crime movies best in China. His first work, Heart Labyrinth, ranks the highest in domestic crime movies on Douban platform and has become a classic of crime movies in the eyes of many movie fans. Director Xin Yukun became famous in one fell swoop, and won many domestic and international awards and nominations with this film. The second work, The Burst of Silence, has the same high score and high reputation, which makes foreign directors of high-scoring crime films also praise it. The film Hot Search is a new realistic work directed by Xin Yukun, and it is also his first collaboration with Zhou Dongyu, which is expected.

Unlike Xin Yukun’s first two films, which tell the criminal stories of marginal people, the film Hot Search closely follows the pulse of the times, focuses its vision on the network environment that is closely related to everyone, and strives to redeem people with realistic storylines and complex humanity, arousing broad and strong social resonance, with a particularly prominent sense of topicality and type.

Zhou Dongyu speaks for the weak.

Song Yang Justin was involved in the game

The film Hot Search tells the story that Chen Miao (Zhou Dongyu), the editor-in-chief of the media, accidentally receives the help of the client while tracking the topic event, and involves a criminal case. Chen Miao’s partner He Yan (Song Yang) and group president Peng Yue (Justin) are involved in it one after another. What is the truth? What are the dangerous secrets behind it? In the face of the parties’ help, how will Chen Miao respond? A just war with the network as the carrier is about to begin.

Zhou Dongyu’s role this time is Chen Miao, the editor-in-chief of the media, which is also her first time to challenge the role of a strong woman in the workplace. Mature and capable in modeling, brave and determined in character, which is quite different from the screen image she used to create. When Chen Miao put all her eggs in one basket to speak for the weak, she also completed her own human redemption. What kind of charisma and profound emotional resonance this role will bring to the audience is fascinating.

Hello, I’m Lu Snake, and today I’m going to talk about football in China!

Speaking of China football, the most important thing recently is that the Football Association has a new head-Song Kai. As a football fan in China, I think this is at least a positive signal, because it shows that the football community in China is trying to improve its own problems and promote the development of football in some way.

Historically, the development of football in China has been plagued by various problems, including mismanagement and corruption. Therefore, changing the president of the Football Association can bring new ideas and directions for the development of football, help solve these problems and promote the healthy development of football in China.

After the new president takes office, he may take a series of measures to improve the football situation in China, including strengthening management, promoting professional development, strengthening the construction of youth training system and improving the quality of coaches and players. From the recent developments of the new head of the Football Association, we can also get a glimpse of it. Then, next, I will sort out the recent events that seem to me to be more important.

1. Debut: "Take youth training as a top priority"

On November 22nd, the second leg of the U15 final in China Youth Championship was held in Weifang, Shandong Province. Football Association President Song Kai, Vice President Xu Jiren and Secretary-General Yuan Yongqing appeared together.

The newest Football Association’s leadership team, which made its first collective appearance, chose youth football matches, fully expressing its attention to youth football. In the words of Song Kai, "China Football Association should take youth training as a top priority." How can we improve the quality of youth training? Song Kai mentioned, first of all, "let the best coaches do youth training", "I have been doing the three big balls in Liaoning for a long time, so I can do some guidance from the policy and system, such as improving the treatment of echelon coaches. In the process of children’s growth, a more competitive competition system is established. "

2. Meeting with AFC President, breaking ice in football foreign affairs.

Song Kai, President of China Football Association, who just arrived in Doha, Qatar, met with Salman, President of AFC, who was also attending the 2022 AFC Awards Ceremony. This is the first time that Song Kai has face-to-face communication with the president of the Asian Football Association as the president of the China Football Association, and it also marks the beginning of the new China Football Association to break the ice for football foreign affairs and take an important first step.

It is understood that during the meeting, Salman reiterated to Song Kai that the AFC will continue to cooperate with the China Football Association to support them in revitalizing football in China.

Subsequently, in its important position in official website, the AFC focused on the meeting between Song Kai and Salman with the title "AFC President praises the football development in China". The AFC quoted Salman as saying: "The AFC will unswervingly strive to make football the number one sport in the Asian continent. I believe that China Football Association can help China football to a higher level under the leadership of President Song Kai. We will also work together for this. " Salman also said: "What is exciting is that we see the determination of the new leadership of China Football Association to develop football and promote the progress of football in China. Football still has great development potential in China. "

3. Study and open the foreign aid policy of the Super League to increase the appreciation of the league.

After Song Kai took office, in view of the situation of the Super League, he said that he would strive to create a professional league that people are satisfied with, and study the foreign aid policy of opening the league against the AFC. At present, the foreign aid policy of the Super League is 654, and his new policy is expected to be "51", that is, five non-nationals and one Asian foreign aid can play at the same time. The implementation of this policy will increase the internationalization and fierce competition of the league, attract more excellent players to China, improve the competitiveness of the league, and at the same time, improve the enjoyment and entertainment, so that fans can enjoy more exciting games.

Finally, I hope the new president can take effective measures to promote the healthy development of football in China, so that we fans can pay more attention to the future of football in China with pride.

If you have any expectations for China football or what do you think of the new head of the Football Association, you are also welcome to leave a message in the comment area for discussion.

　　In the diving field, China team has the reputation of "Dream Team". A diving action completed in a few seconds, the average audience usually sees the effect of entering the water, that is, the size of the splash. In fact, splashing is also a high-precision technology. A reporter from Beijing Morning Post recently invited Yu Fen, head coach of Tsinghua diving team, to give a detailed answer to this technology.

　　Hand shape

　　There are slight differences between China and foreign countries.

　　In the diving competition, watching the slow-motion replay will find that the athletes enter the water with their palms in contact with the water surface, not the fingertips as generally believed. A "technical post" circulating on the Internet explains that water spray belongs to the category of fluid mechanics, that is, the process of collision between solid and fluid. Entering the water with your fingertips is equivalent to forming a wedge, so when you fall into the pool, you will find a way out along the direction of least resistance because of the incompressibility of water, and the inclined plane of the wedge is this direction. However, when the object colliding with water has a certain cross section, the water mainly moves laterally, and it can’t be rushed up due to the pressure of the surrounding water, which is the reason why the palm spray is small.

　　Yu Fen introduced that in the past 40 years, the technology of pressing the splash with the palm of your hand has been widely used in countries with relatively advanced diving. "We call it the palm-turning technology. The main point of action is to point your palm at the point where you want to enter the water at the moment of entering the water, and hold the other hand with one hand. " This is the hand type commonly used by athletes in China, while some foreign athletes will put their thumbs together, their fingers open and their hands crossed when entering the water, with their palms facing the water. In addition, there are two unusual hand types: one is that the five fingers are open, and the two hands are kept at a distance of about 10 cm; the other is that the two thumbs are clasped, the fingers are bent and the palms are facing the water.

　　posture

　　Splash suppression is not just about hands.

　　Yu Fen told the Beijing Morning Post that the hand shape is only one of the details of the entry action, but it is not the only criterion to judge the entry effect, which determines that the entry action needs a series of essentials.

　　"Simply put, the athlete’s body should enter the water perpendicular to the water surface. The specific requirements are that the arms should be close to the ears, and the head, shoulders and toes should be in a straight line. At the moment when the palm touches the water, the body should be in a straight line of 90 degrees with the water, and the waist should not be loose, and the buttocks should be clamped. Sometimes you can see athletes appear when they enter the water ‘ Passed ’ Or ‘ Not enough ’ Phenomenon, the water is very big, and the completion of the branch is very low. The reason for this phenomenon is not necessarily that the water entry technology is not done well, and problems often appear in the air. The specific reasons need to be analyzed in detail. "

　　In fact, when entering the water from a 10-meter platform, the instantaneous speed reaches 15 meters per second. Because it is difficult to completely stop the rotation of the body in the air when entering the water, the palm needs to adjust its direction, not just parallel to the water. This is to avoid injury. Yu Fen introduced that on the basis of mastering the essentials, athletes also need to protect themselves through minor adjustments.

　　opportunity

　　Opening time affects the effect

　　"As mentioned earlier, there is a problem with the water entry effect, and we can’t just find problems from this link. As the last link in diving, the technique of splashing can really attract the attention of ordinary audience, but it is difficult to make it clear simply by talking about this link, just as athletes can’t just practice splashing. When they are training, if there is a problem in one link, they will have to re-enter the springboard or platform, and all the processes will be repeated. "

　　Yu Fen introduced that the whole process of diving is divided into seven links from the beginning of the athlete’s running platform or walking board to the end when the toes are completely below the water surface. "They are all interlocking. If one link is not done well, it will directly affect the back until it enters the water." Although when watching the diving competition, I sometimes hear the commentary mention that "the splash effect is ok, and it can be somewhat remedied", but judging an action, flaws and mistakes still cannot escape the eyes of the referee.

　　"Every movement has to go through thousands of exercises before it can be polished to the best. Before pressing the spray, the forming time of the action is also very important, which is what we call ‘ Open the opportunity ’ If it is opened too early, the athletes will stay in the air for a long time and cannot concentrate their strength completely; If it is too late, there is no time to adjust your body to the best position angle. "

　　give a mark

　　The referee won’t just stare at the splash.

　　Similarly, the referee’s score should also be based on the whole process of the diver’s completion of the action. "Not to say that in the end, the referee will give him points. (The splash is not pressed well) it does have an impact, but if the air attitude and the angle of entry are well done from the beginning of the take-off, this action can still be considered successful and the score can still be higher. "

　　There is an important message in the scoring of diving rules: the judge will evaluate the score according to the athlete’s run-up (i.e., running board and platform), take-off, air and water entry, and also explain the integrity of the scoring process. Therefore, athletes should run smoothly during the competition, take off decisively and forcefully, take off at an appropriate angle and with a certain height; Beautiful posture in the air, tumbling and turning quickly; When a person dives, his body is perpendicular to the water surface, and the smaller the splash, the better. Yu Fen said: "In fact, from the moment an athlete appears, the referee begins to score his temperament, including every detail of the completion of the action. From the training, we require athletes to do every detail in order to conquer the referee in the official competition. "

　　■ knowledge post

　　Introduction action "jumping popsicle"

　　It’s hard to dance well.

　　It is said that some people accidentally discovered in the "popsicle" diving that it is better to use the soles of their feet instead of stretching their toes, so they brought water impact’s splash pressing technology. And "popsicle" is just the enlightenment action of zero-based diving. You don’t need to stand upside down, just straighten up and jump into the water. This action is easy to say, and it takes time and energy to train it well. As Yu Fen, head coach of Tsinghua University Diving Team, said: Diving is a sport in which people exert their control over their bodies to the extreme.

　　The correct posture of "popsicle" diving is: standing in front of the platform, arms open and body in a T-shape; At the moment of jumping out of the platform, your feet should be off the ground at the same time, your arms should be lifted up and your body should be y-shaped; When entering the water, the arm should draw an O-shape in the air, and finally put the arm close to the thigh and enter the water. The whole action is completed in a few seconds, and you also need to control your body. In the star diving programs in the previous two years, the zero-based stars were in a lot of situations when they completed this basic movement, and even appeared "slamming the door", that is, the body slammed into the water. If you don’t control your limbs properly, you are most likely to break the door panel, causing bruises and redness. Some experts have analyzed that if you fall into the water from a 10-meter platform, it is equivalent to falling vertically from a height of 1 meter on the plastic playground.

　　At the same time, the stars participating in the program are all adults, and even tall models. The selection of materials for diving enlightenment training requires moderate height, small pelvis and light body. It was only after the full development that I began to contact diving, and the star diving program was really beyond my power.

In the camp of "not the same fruit", supporters list the differences between pineapple and pineapple in every detail, for example, pineapple has fewer thorns, does not need to dig trenches, does not need to be soaked in salt water, and is more noble than pineapple (no, the pineapple party refuses).

The other camp believes that pineapple is actually a pineapple, and the two are like tomatoes and tomatoes, potatoes and potatoes.

So, what is the relationship between pineapples and pineapples on the market?

The dispute between pineapple and pineapple is actually an "infighting"

To understand this puzzle that has puzzled the fruit circle for a long time, we must first talk about the pineapple family.

According to the "Flora of China", the common name of pineapple is pineapple.

Botanically speaking, they are the same plant of the genus Bromeliaceae.

There are more than 2,000 employees in 45 genera in this "department" of Bromeliaceae, among which only one species of pineapple has economic cultivation value, and the rest have become ornamental flowers.

Potatoes, perennial evergreen herbaceous pulpy plants of bromeliaceae.

In 1935, there were 135 recorded pineapple varieties. According to the characteristics of fruits, they can be divided into four categories: Cayenne Group, Queen Group, Spanish Group and hybrid group.

If you go to a supermarket or a fruit shop to buy pineapple, you will probably buy a queen variety called Bali.

In 2015, about 80% of the main pineapple producing areas in Chinese mainland were cultivated in Bali.

Its leaves are a little prickly, and it will prick your hand. If you cut it open, you will find many black round fruit eyes, which are actually the stigma and stamens left in the pulp of pineapple.

After removing them, you can eat only about 57% of the pulp.

If you are persuaded by Bali pineapple and want to switch to "pineapple", then the clerk may recommend some special varieties to you, such as golden diamond pineapple, perfume pineapple, peeled pineapple and so on, but they are actually different members of the pineapple family.

Take Golden Diamond Pineapple as an example, it is a hybrid variety bred in Taiwan Province area, numbered Tainong 17. In 2018, 85% of the pineapples cultivated in Taiwan Province were golden diamonds.

Its size is one or two times larger than that of Bali, but its fruit eye is only half as deep as that of Bali. After cutting the peel, it can be eaten directly, with a crisp taste and overflowing juice.

Because the bromelain content in golden diamond pineapple is relatively low, it won’t sting too much when eaten.

However, its excellent taste and quality also mean that you need to pay more money to take it home. For example, in Baiguoyuan, a chain fruit shop, the price of an A-grade Bali pineapple is about 13.5 ~ 15.8 yuan/kg, while the price of a golden diamond pineapple of the same level is 42 ~ 45 yuan/kg.
