Meta is hard and OpenAI, and the domestic ＂small model＂ official announces open source. Where is the ＂Hundred Models War＂ going？

　　Since the beginning of this year, the global Internet giants have set off a "hundred-model war", and Microsoft, Google, Baidu and Ali have come to the end one after another. After more than half a year of competition, technology giants are welcoming a new round of road disputes around the big model ecology: facing the parameter "ceiling", will the future of the big model be closed or open?

　　The open source model can run on a home computer.

　　On August 3rd, two open source models, Qwen-7B and Qwen-7B-Chat, were put on the domestic AI developer community "ModelScope", which were Alibaba Cloud Tongyi Qianwen’s 7 billion parameter general model and dialogue model respectively. Both models were open source, free and commercially available.

　　According to reports, Tongyi Qianwen Qwen-7B is a pedestal model that supports many languages such as Chinese and English, and it is trained on more than 2 trillion token (text unit) data sets, while Qwen-7B-Chat is a Chinese-English dialogue model based on the pedestal model, which has reached the cognitive level of human beings.In short, the former is like a "foundation" and the latter is a "house" on the foundation.

　　The actual test shows that the comprehensive performance of Qwen-7B model is good. Among them, on the English proficiency evaluation benchmark MMLU, the score is generally higher than that of the mainstream models with the same parameter scale, even surpassing some models with 12 billion and 13 billion parameter scales. On the Chinese evaluation C-Eval verification set, the model also achieved the highest score of the same scale. Qwen-7B model is also among the best in evaluating GSM8K in mathematical problem solving ability and HumanEval in code ability.

　　That is to say,In the tests of Chinese and English writing, solving mathematical problems and writing codes, Qwen-7B model is properly a "master of learning", and its score even exceeds the international mainstream model with the same parameter level.

　　Besides, the industry is more concerned about the usability of Qwen-7B model. As we all know, the training and operation of mainstream large models need special AI training chips (such as NVIDIA A100), which are not only expensive, but also as high as 10,000 — per NVIDIA A100; 15,000 dollars, and it is monopolized by countries such as Europe and the United States, and it is almost impossible to buy it in China.The domestic Qwen-7B model supports the deployment of consumer graphics cards, which is equivalent to a high-performance home computer to run the model.

　　Thanks to free commercialization and low threshold, the Qwen-7B model has been put on the shelves, which has attracted the attention of AI developers.In just one day, on the code hosting platform GitHub, the Qwen-7B model has been collected by more than a thousand developers, and most of the questioners are Chinese developers.As Alibaba Cloud said in the statement: "Compared with the lively AI open source ecology in the English-speaking world, the Chinese community lacks an excellent pedestal model. The addition of Tongyi Qianwen is expected to provide more choices for the open source community and promote the open source ecological construction of AI in China. "

　　Open source or closed?

　　In fact, Qwen-7B model is not the first big open source model. In fact, GPT-2, the predecessor of ChatGPT, is also completely open source. Its code and framework can be used for free on the Internet, and related papers can be consulted. However, after ChatGPT spread all over the world, OpenAI chose closed-source development, and the model codes such as GPT-3 and GPT-4 have become the trade secrets of OpenAI.

　　The so-called open source is open source code.For example, once the big model is declared open source, anyone can publicly obtain the model source code, modify it or even redevelop it within the scope of copyright restrictions. To make a simple analogy,The source code is like the manuscript of a painting, and everyone can fill in the colors according to the manuscript to create their own artistic paintings.

　　Closed source is just the opposite of open source.Only the source code owner (usually the software developer) has the power to modify the code, others can’t get the "manuscript" and can only buy the finished product from the software developer.

　　The advantages and disadvantages of open source and closed source are very obvious. After open source, the big model will undoubtedly attract more developers, and the application of the big model will be more abundant, but the corresponding supervision and commercialization will become a difficult problem, which is prone to the embarrassing situation of "making wedding clothes for others".After all, open source considers ecological co-prosperity, and it is difficult to figure out the economic account of how much money can be earned at this stage, and these problems happen to be opportunities to close the source.

　　Open source or closed source, this is a big model of life and death, the international giants have given the answer.

　　Meta, the parent company of Facebook, released the big model Llama2 last month, which is open source and free for developers and business partners, while OpenAI firmly chose GPT-4 closed source development, which not only can maintain OpenAI’s leading position in the generative AI industry, but also can earn more revenue. According to the authoritative magazine Fast Company,OpenAI’s revenue in 2023 will reach 200 million US dollars, including providing API data interface services and subscription service fees for chat bots.

　　Domestic big models have gradually begun to "go their separate ways".Alibaba Cloud’s General Meaning ModelAs early as April this year, it was announced to be open to enterprises, and the open source of Qwen-7B model will go further.ERNIE Bot of BaiduIt has also recently announced that it will gradually open the plug-in ecosystem to third-party developers to help developers build their own applications based on the Wenxin model.

　　In contrast, Huawei does not take the usual path. When the Pangu Big Model 3.0 was released, Huawei Cloud publicly stated that,Pangu modelThe full stack technology is independently innovated by Huawei, and no open source technology is adopted. At the same time, Pangu Big Model will gather numerous industry big data (involving industry secrets, etc.), so Pangu Big Model will not be open source in the future.

　　The big parameters are still small and beautiful.

　　In addition, the open source of Qwen-7B model brings another thought:How many parameters do we need a big model?

　　There is no denying that,The parameter scale of the large model is constantly expanding.Take the GPT model under OpenAI as an example. GPT-1 only contains 117 million parameters, and the parameters of GPT-3 have reached 175 billion, which has increased by more than 1000 times in a few years, while the parameters of GPT-4 have exceeded the trillion level.

　　The same is true of large domestic models. Baidu Wenxin model has 260 billion parameters, Tencent mixed-element model has reached 100 billion parameters, Huawei Pangu model has been estimated to be close to GPT-3.5, and ali tong Yida model has officially announced 10 trillion parameters … …According to incomplete statistics, there are at least 79 large-scale models with over 1 billion parameters in China.

　　Unfortunately, the larger the parameter, the stronger the capability of the large model. At the World Artificial Intelligence Conference, Wu Yunsheng, vice president of Tencent Cloud, has a very appropriate metaphor: "Just like athletes practicing physical strength, weightlifters need to lift 200 kilograms of barbells, and swimmers need to lift 100 kilograms. Different types of athletes don’t need everyone to practice 200 kilograms of barbells."

　　As we all know,The higher the parameters of the large model, the more resources and costs are consumed.However, it is not necessary to blindly pursue "large scale" or "high parameters" to deepen the vertical large-scale model of the industry, but to formulate relevant model parameters according to customer needs. For example, the BioGPT-Large model has only 1.5 billion parameters, but its accuracy in biomedical professional tests is better than that of the general model with 100 billion parameters.

　　Sam Altman, co-founder of OpenAI, also publicly stated that OpenAI is approaching the limit of LLM (Large Language Model) scale. The larger the scale, the better the model is, and the parameter scale is no longer an important indicator to measure the quality of the model.

　　Wu Di, the head of intelligent algorithm in Volcano Engine, has a similar view. In the long run, reducing costs will become an important factor in the application of large models. "A well-tuned small and medium-sized model may perform as well as a general large model in a specific job, and the cost may be only one tenth of the original."

　　At present, almost all domestic science and technology manufacturers have got tickets for big models, but the real road choice has just begun.

The spy war is never over, the spy is around, and the Chinese version of ＂Mr. and Mrs. Smith＂ is so good at acting.

After "Undercover" and "Mask", Zhang Haidong’s third spy war drama "Opponent" came!

There are spoilers in this article.

one

The market in the old city of Xiazhou, the most mixed place, has many pickpockets committing crimes.

No, a pickpocket accidentally put his hand into the policeman’s trouser pocket, and it was too late for him to see the photo of the policeman. Li Tang (Guo Jingfei) chases quickly and ties the thief to a telephone pole.

Then Li Tang wore a police uniform and walked into a dirty rental house. Under Li Tang’s torture, Brother Hei admitted that Yaoji owed three million usurers, but he didn’t know the whereabouts of Yaoji. At the same time, Black Brother also noticed that Li Tang was not a policeman.

In fact, Li Tang is an overseas spy. He usually travels as a taxi driver, and when he finishes his task, he will disguise himself as a variety of roles.

Li Tang’s wife Ding Meixi (Tan Zhuo) is also an overseas spy and a teacher. Ding Meixi repeatedly used her body to lure people into the water in order to obtain information. The two men will do whatever it takes to achieve their goals, and as for the little secret between them, they will only see through it.

On the other hand, Duan Yingjiu (Yan Bingyan), a national security officer, is also looking for the spy Yaoji. By looking up the phone records and comparing the take-away orders, she has locked the most likely hiding place of Yaoji. However, the national security personnel were still late. After seeing Li Tang, Yao Ji committed suicide after saying his last words …

However, the investigation of Yaoji still didn’t stop. Duan Yingjiu began to arrange Ding Xiaohe, a newcomer to Guoan, and his party to collect the information that Yaoji might have left in the bank and analyze who Yaoji left the money to.

Ding Xiaohe is Ding Meixi’s younger brother. Ding Xiaohe announced that he had officially joined Guoan, and the couple were terrified. Ying Jiu had long been suspicious of the couple, which undoubtedly put them in deep danger.

It wasn’t long before Mr. and Mrs. Li Tang received the task of killing Bao Ping, a spy. They switched Bao Ping’s asthma medicine to spray to induce asthma, which led to Bao Ping’s death. The couple will try to explain to Ding Xiaohe why they bought a heart spray that the whole family can’t use. So Li Tang sacrificed his health and directed and performed a heart attack recurrence.

He and Ding Meixi also staged a divorce storm in which the husband found out that his wife had broken a whore, so as to divert the attention of the national security personnel, and a catch me if you can began.

A good script is the foundation, and the actor is the soul of the play. From the realistic "I am Yu Huanshui", the audience will feel Guo Jingfei’s control over the inner complex drama of the little people.

In this play, Guo Jingfei plays a spy who walks on the tip of a knife every day, and I don’t know when he dies. But at the same time, he is also an ordinary person, who will bend his back for five buckets of rice and worry about his daughter’s puppy love. When his wife didn’t come home late at night, Guo Jingfei was lying in bed counting condoms and found that one was missing. She was silent and lost in thought.

The wife found that her daughter always stole her cosmetics and counted condoms for fear that her daughter would have an accident. Clearly missing one, Guo Jingfei paused for a few seconds, eyes flashing, covering up the past. In this performance, Guo Jingfei vividly interprets the forbearance of a spy husband.

The reason why Guo Jingfei can show the fragility and powerlessness of the little people so vividly is that he devoted himself to the script study and really realized the sense of bringing in. The producer of "Opponent" said in an interview: "Guo Jingfei was deeply moved when he got the script. After watching 10 episodes, he couldn’t put it down and decided to participate. " It is not so much that Guo Jingfei is chosen in this play as that they have achieved each other.

Tan Zhuo is also highly compatible with the role of Ding Meixi. Ding Meixi is a glamorous female teacher, an unscrupulous female spy, and a wife and mother. For multiple identities, Tan Zhuo’s performance is very layered.

When she was blocked at home by Duan Ying-jiu, the other party kept asking her for soul torture, and Tan Zhuo ignited the female spy’s inner anxiety, habitually clasping her hands and fidgeting. I’m afraid that a spy with a good psychological quality will panic when encountering this kind of attack.

When her husband broke into the house with a belt to help clear the gap, Tan Zhuoming was relieved. He glanced at Duan Yingjiu timidly, but his heart was exulting. The detailed handling was too skillful.

It was the first time for several actors in the play to cooperate, but they entered the role faster than expected. The producer revealed: "This is due to the trust and tacit understanding they have established when they read the script around."

The content of Opponent is unrepeatable, mainly because the form of spy war is connected with life, involving many bridges that need to be kept secret.

This drama starts from the daily life of spies and national security personnel and reveals their unknown side. For ordinary people, watching a group of mysterious workers fight against each other is a different experience.

"Opponent" doesn’t have the high-tech and enviable work of others. What I feel is that the anti-espionage work is not easy, and the spies are not glamorous on the surface, but extremely dangerous.

The spy couple in the play are faced with the tempering of life. Ding Meixi was found by the school to make up lessons outside, and the bonus was deducted. The original economy was stretched, and she also strayed into the illegal fund-raising trap and lost all her money. Li Tang accidentally broke his tooth in the pursuit mission, and went to the hospital for treatment, but he was scared out by the high medical expenses. The handling of this comedy shows the fact that spies are "smarter than they are" and "being spies is not glamorous".

There is also a positive image of Duan Yingjiu, who sacrificed his life for his mission and responsibility. Not only did family conflicts continue and he could not lead a normal life, but even his body turned red. However, the drama does not use a lot of pen and ink to describe the emotional side, but presents the greatness and selflessness of the national security personnel through life scenes.

Wang Xiaoqiang, the screenwriter of "Opponent", said when he turned on the phone: "I put my views on the world, my emotional experience and my understanding of faith in this story over the years." Because of this, the play is more warm. And a work with temperature can make the audience resonate.

In today’s era of development and peace, anti-espionage work has always existed in various forms that we don’t know. An unconscious word, a casually discarded courier, may reveal secrets. Perhaps "the spy may be around you"-as the drama is broadcast, the context becomes clearer, and the dispute between the national security personnel and the spy becomes more intense. They will continue to compete for victory in the sun. We will wait and see!

＂The Wind Rises in Longxi＂： There is a spy war, and you can see the character’s character.

Taking the little people’s ideal persistence as the eye of the play, and using the type of ancient costume and spy war as the loom, the wind of "Wind Up in Longxi" blew up.

Author: and song

Chen Gong, a spy on three sides, gave his life for the overall situation; Li Yan, who lost power, re-examined the development of Shu; Xun Xu, who knows all the truth, will go to Soochow to set up a new spy network. ……

　

On May 7th, the spy war of the Three Kingdoms in "The Wind Rises in Longxi" came to an end, and the finale explained the fate of all the characters. Also, through the dialogue between Xun Xu and Chen Gong, the "trap" that runs through the whole play was resumed, and Chen Gong was lonely and brave, which made the emotional concentration of the play reach a climax.

Since its launch, the plot and emotional impact of "The Wind Rises in Longxi" have been the key to attract audiences. The drama uses ancient costume and spy war as a kind of nesting machine, taking the fall of the street pavilion as a guide, and dissects the intelligence war between Shu Han and Cao Wei from two little people, Chen Gong and Xun Xu. After life and death, love and hate, they still abide by loyalty, just as director Lu Yang explained to them, "In the face of difficulties, little people can make heroic choices."

　

High-density narration, showing the tension of spy war in ancient costume

Compared with most types of dramas, spy war dramas require more details, drama concentration and story depth. The characters often stir up the times in the dark and reveal the brilliance of human nature in the narrow gap of existence. In order to meet the characteristics of this type of drama, such as spectacle, strong plot and profound conception, many classic spy war dramas on the screen, such as Vow Silent, Hidden, Kite and Pretender, choose to expand the spy sea in troubled times.

　

Accustomed to the silent battlefield in modern history, "The Wind Rises in Longxi" sets the story in the Three Kingdoms, focusing on the secret confrontation of small people under the torrent of the times, which can be said to meet the audience’s innovative expectations for spy war dramas to some extent.

　

In a spy war between Shu Han and Cao Wei, the main characters’ multiple identities kept switching, and there was a struggle between the enemy and me. The ups and downs of characters experience made the story ups and downs and the narrative was extremely compact.

　

The design of long lines and short lines in the play has played a new role in "storytelling". Finding out that Candle dragon, a Cao Wei spy lurking in Shu Han, is a long term, while breaking the bureau after the exposure of Bai Di, obstructing the Qing Ping plan of Cao Wei’s intelligence department and cleaning the secret network of Cao Wei’s intelligence department are short term.

　

The wiring and winding of short stories are not procrastinating, and each line is relatively independent and clear. As a whole, it is complex and wonderful without losing logic. On social media, some netizens described the drama-chasing experience as "the pleasure of rising and falling, and sweeping with the stand".

　

The high-density narrative of "The Wind Rises in Longxi" challenges the double-speed playing habits of current netizens, and makes the audience slow down actively with wonderful foreshadowing. In this reversal spy war, the title of each episode, the dialogue between characters and even some small shots are "hidden mystery". Some viewers have found that some bridges that are difficult to clarify at first can find the answer after two or even three brushes. For example, Chen Gong replaced Cao Wei’s identity as an intelligence agent, but he was able to quickly match the secret code with the roadside driver, laying the groundwork for his reversal as a second-generation "Candle dragon"; After the news of the death of a generation of "Candle dragon" arrived, the camera turned to Feng Ying, the head of the intelligence service. It is self-evident who moved the hand …

Color, light and shadow, props, etc. also assist the story. The turquoise tone of Nanzheng in Shu Han and the grayish yellow tone of Tianshui in Cao Wei help the audience distinguish the regional differences; Men’s beard was an aesthetic and fashion in the Three Kingdoms period, and the beard styles and lengths of different male characters in the play coincided with their personality and status. There are not many props in the indoor scene. Production designer Han Zhong explained, "In the era of frequent wars, people are displaced and the scenery is simple, so the traditional aesthetics of’ sparse and impenetrable’ is chosen to run through the whole drama."

A forbearing and enthusiastic person with insight.

Lu Yang mentioned that he was attracted by the story "The Wind Rises in Longxi" not only because of the combination of spy war and the Three Kingdoms, but also because the little people in this era had no choice but to choose in such a fierce struggle environment.

　

In the play, the protagonists have no legendary appearance, no omniscient perspective and can’t open their "golden fingers". They should maintain a highly rational mental state in extremely complicated situations, "shield" real emotional fluctuations, and even the audience should hold their breath. A scene of where will you go, a husband and wife, is moving. While Chen Gong and his wife Zhai Yue were lurking at the same time, Zhai Yue was tortured to extract a confession after being exposed, and his life was soon over. Their last farewell was all about handing over information, and the sobs belonging to the husband and wife could only be hidden in the darkness.

　

The small emotion of "suddenly venting" in the details, even if it is subtle, also shows the strength of character. In a cold environment, it reveals warm colors. The protagonists are intelligence workers who must be heartless, but also ordinary people who are flesh and blood and have weaknesses that will be fragile.

　

In the thrilling contest and the plot of life and death, the emotional relationship between characters has also been adjusted to a certain extent. The brotherly relationship between Chen Gong and Xun Xu, the in-laws relationship between Feng Ying and Sun Ling, the uncle relationship between Guo Huai and Guo Gang, and the teacher-student friendship between Chen Gong and Li Yan are the emotional ties that connect long and short stories, and they also decode spy war and "intelligence workplace" from the perspective of social relations.

　

People can’t help themselves in troubled times, but it doesn’t mean that little people will be weakened in their ideals and beliefs. Chen Gong, the "chess eye" of the two countries, was never willing to be only a tool man. At the end of the story, he became a "chess player", seeking the optimal solution for everyone while completing his tasks, even if it was at the expense of his own life.

　

Sticking to the morality in one’s heart in one’s own way is an adventure, and it is also an amplification of ordinary people’s "fearless" and "promising". This is also the subtle empathy between the audience and the role.

　

Not only Chen Gong, but Xun Xu, who made a thorough investigation of the "Candle dragon" case, also reflected the stubborn but passionate side of most people.

　

Time goes back to Xun Xu’s involvement in the whole spy war. In the dark interrogation room, he was hanged upside down and drowned. He remembered the ordinary meal he had with his brother Chen Gong and his cousin Zhai Yue. At the dinner table, he (she) who had carried out intelligence work raised their glasses and agreed, "In order to stop fighting" and "For people like you and me to live a good life".

　

Taking this as an appointment, they rushed into the world where candlelight was swaying, but they could learn from sincerity.

　

If the narrative innovation of ancient costume and spy war type nesting makes The Wind Rises in Longxi attract the audience’s attention, then showing the emotional expression of little people who persist in their ideals and maintain their morality in troubled times will retain the audience’s heart to the greatest extent.

Like it, it’s great! China has made a major breakthrough in the field of electric vehicles.

　　Cctv newsThe 2022 Winter Olympic Games will be held in China, and the China government has once again made a promise of "Green Olympics". Around this goal, it is an important link to realize green transportation during the Olympic Games. On August 31st, Beijing Institute of Technology and other research teams released an achievement: the all-weather battery product was successfully developed, that is, the battery of electric vehicles can still work normally under all climatic conditions, including extreme low temperature.

　　In the cold environment, electric vehicles will face challenges.

　　After investigation, during the Beijing Winter Olympics, vehicles will face a low temperature of -20℃ to -30℃, and the use of new energy vehicles will face the following challenges ↓ ↓

　　The charging and discharging characteristics of the power battery become worse!

　　Battery capacity and life will also decay!

　　These will lead to a significant decline in vehicle driving range and vehicle dynamic performance!

　　Sun Fengchun, Director of the National Engineering Laboratory of Electric Vehicles of Beijing Institute of Technology and Chief Expert of the Expert Group of Beijing New Energy Vehicle Association:

　　Now the electric vehicle (cruising range) has reached more than 300 kilometers, but it may only run for dozens of kilometers at MINUS 10℃.The farthest distance between the two venues of Beijing Winter Olympics, that is, the Chongli distance from Wukesong in Beijing to Zhangjiakou is 260 kilometers. How to last the electric vehicle at low temperature is a problem that must be solved.

　　New technology, let electric vehicles break through the low temperature forbidden zone

　　The team led by Professor Sun Fengchun developed the world’s first all-climate battery product by using the rapid thermal conductivity generated by metal heating inside the battery. The key technologies are as follows ↓ ↓

　　A layer of nickel-platinum sheet was added to the existing lithium battery.

　　Connect the power supply, and the battery can be heated quickly!

　　Sun Fengchun:

　　At MINUS 30℃, the temperature of our battery rises to above zero in twenty seconds, so it can work very well and has no influence on the life of the battery. This is the core technology. In other words, there is no forbidden area for electric vehicles, which is a milestone principle and technology in this respect.

　　Low temperature environment, all the key technologies of new energy vehicles are overcome.

　　In addition, key technologies such as vehicle system integration and control in low temperature environment have also made breakthroughs. The cooperative control technology of automatic driving and automatic charging has laid a solid foundation for the application of new energy vehicles during the Winter Olympics.

　　Sun Fengchun:

　　From the battery cell, battery system to the system integration of the whole vehicle, it should be said that the technology has been completely overcome.Our core key components are required according to the standard of low temperature of MINUS 45℃ to ensure that there will be no problems during the Winter Olympics.

　　At the end of this year, all-weather electric vehicles will be launched.

　　According to reports, the first batch of all-weather electric vehicles in the world will be released at the end of December this year, and then they will go to Mohe and other alpine regions for experiments at around MINUS 45 C. It is estimated that in 2020, the development of 11 product prototypes of four types of vehicles will be completed, and the demonstration operation will begin.

　　Zhang Jihong, Deputy Director of Beijing Municipal Science and Technology Commission:

　　We should further integrate some technologies from Beijing, China and even foreign countries to tackle key problems in Industry-University-Research. Whether it is low-temperature battery technology or driverless technology, a complete and comprehensive presentation can be obtained during the 2022 Winter Olympics.

The Table Tennis World Cup will be held in Macau, China in April 2024.

On December 11th, according to Mi Gu Sports, the ITTF announced that the men’s singles World Cup and the women’s singles World Cup will return at the same time, and the competition will be held in April, 2024 at the Galaxy Variety Hall in Macau, China.

Liu Guoliang, Chairman of the Board of Directors of WTT World Table Tennis Federation, First Vice Chairman of ITTF and Chairman of China Table Tennis Association, said: "In April next year, the men’s and women’s singles World Cup will return to Macau, and table tennis fans from all over the world are welcome to gather in Macau again."
