ChatGPT: Explained to Kids(How ChatGPT works)

Chat means chat, and GPT is the acronym for Gene Rate Pre trained Transformer.

Genrative means generation, and its function is to create or produce something new; Pre trained refers to a model of artificial intelligence that is learned from a large amount of textual materials, while Transformer refers to a model of artificial intelligence.

Don't worry about T, just focus on the words G and P.

We mainly use its Generative function to generate various types of content; But we need to know why it can produce various types of content, and the reason lies in P.

Only by learning a large amount of content can we proceed with reproduction.

And this kind of learning actually has limitations, which is very natural. For example, if you have learned a lot of knowledge since childhood, can you guarantee that your answer to a question is completely correct?

Almost impossible, firstly due to the limitations of knowledge, ChatGPT is no exception, as it is impossible to master all knowledge; The second is the accuracy of knowledge, how to ensure that all knowledge is accurate and error free; The third aspect is the complexity of knowledge, where the same concept is manifested differently in different contexts, making it difficult for even humans to grasp it perfectly, let alone AI.

So when we use ChatGPT, we also need to monitor the accuracy of the output content of ChatGPT. It is likely not a problem, but if you want to use it on critical issues, you will need to manually review it again.

And now ChatGPT has actually been upgraded twice, one is GPT4 with more accurate answering ability, and the other is the recent GPT Turbo.

The current ChatGPT is a large model called multimodality, which differs from the first generation in that it can not only receive and output text, but also other types of input, such as images, documents, videos, etc. The output is also more diverse. In addition to text, it can also output images or files, and so on.

Zuckerberg surfed and drank beer on vacation, Musk: I prefer to work
After Meta CEO Mark Zuckerberg posted a video on his Facebook and Instagram accounts of his free time during the Independence Day holiday on the X platform, Musk said, "I prefer to work." Zuckerberg posted a video of himself surfing on a hydrofoil in a tuxedo, waving an American flag and drinking a beer, and wrote: "Happy birthday America." The video quickly went viral, and after greg shared it on the X platform, Musk replied: "I hope he continues to have fun on the yacht." I prefer to work." Musk, a workaholic, attended the 29th annual Barron Investment Conference in November 2022, where he said: "My workload went from 78 hours a week to 120 hours a week..." In 2018, he slept on the floor of the Gigafactory in Fremont in an effort to ramp up production of the Tesla Model 3.
China proposes to establish BCI committee to strive for domestic innovation
China is mulling over establishing a Brain-Computer Interface (BCI) standardization technical committee under its Ministry of Industry and Information Technology (MIIT), aiming to guide enterprises to enhance industrial standards and boost domestic innovation. The proposed committee, revealed by the MIIT on Monday, will work on composing a BCI standards roadmap for the entire industry development as well as the standards for the research and development of the key technologies involved, according to the MIIT. China has taken strides in developing the BCI industry over the years, not only providing abundant policy support but also generous financial investment, Li Wenyu, secretary of the Brain-Computer Interface Industrial Alliance, told the Global Times. From last year to 2024, both the central and local governments have successively issued relevant policies to support industrial development. The MIIT in 2023 rolled out a plan selecting and promoting a group of units with strong innovation capabilities to break through landmark technological products and accelerate the application of new technologies and products. The Beijing local government also released an action plan to accelerate the industry in the capital (2024-2030) this year. In 2023, there were no fewer than 20 publicly disclosed financing events for BCI companies in China, with a total disclosed amount exceeding 150 million yuan ($20.6 million), Li said. “The strong support from the government has injected momentum into industrial innovation.” The fact that China's BCI industry started later than Western countries such as the US is a reality, leading to the gap in China regarding technological breakthroughs, industrial synergy, and talent development, according to Li. To further close gaps and solve bottlenecks in BCI industrial development, Li suggested that the industry explore various technological approaches to suit different application scenarios and encourage more medical facilities powered by BCI to initiate clinical trials by optimizing the development of BCI-related ethics. Additionally, he highlighted that standard development is one of the aspects to enhance the overall level and competitiveness of the industry chain, which could, in turn, empower domestic BCI innovation. While China's BCI technology generally lags behind leading countries like the US in terms of system integration and clinical application, this has not hindered the release of Neucyber, which stands as China's first "high-performance invasive BCI." Neucyber, an invasive implanted BCI technology, was independently developed by Chinese scientists from the Chinese Institute for Brain Research in Beijing. Li Yuan, Business Development Director of Beijing Xinzhida Neurotechnology, the company that co-developed this BCI system, told the Global Times that the breakthrough of Neucyber could not have been achieved without the efforts of the institute gathering superior resources from various teams in Beijing. A group of mature talents were gathered within the institute, from specific fields involving electrodes, chips, algorithms, software, and materials, Li Yuan said. Shrugging off the outside world's focus on China’s competition with the US in this regard, Li Yuan said her team doesn’t want to be imaginative and talk too much, but strives to produce a set of products step by step that can be useful in actual applications. In addition, Li Wenyu also attributed the emergence of Neucyber to the independent research atmosphere and the well-established talent nurturing mechanism in the Chinese Institute for Brain Research. He said that to advance China’s BCI industry, it is necessary not only to cultivate domestic talents but also to introduce foreign talents to enhance China's research and innovation capabilities. The proposed plan for establishing the BCI standardization technical committee under the MIIT will solicit public opinions until July 30, 2024.
Record numbers of people are flying. So why are airlines’ profits plunging?
New York CNN — A record number of passengers are expected to pass through US airports this holiday travel week. You’d think this would be a great time to run an airline. You’d be wrong. Airlines face numerous problems, including higher costs, such as fuel, wages and interest rates. And problems at Boeing mean airlines have too few planes to expand routes to support a record numbers of flyers. Strong bookings can’t entirely offset that financial squeeze. The good news for passengers is they will be spared most of the problems hurting airlines’ bottom lines — at least in the near term. Airfares are driven far more by supply and demand, not their costs. But in the long run, the airlines’ difficulties could mean fewer airline routes, less passenger choice and ultimately a less pleasant flying experience. Profit squeeze Industry analysts expect airlines to report a drop of about $2 billion in profit, or 33%, when they report financial results for the April to June period this year. That would follow losses of nearly $800 million across the industry in the first quarter. Labor costs and jet fuel prices, the airlines’ two largest costs, are both sharply higher this year. Airline pilot unions just landed double-digit pay hikes to make up for years of stagnant wages; flight attendant unions now want comparable raises. Jet fuel prices are climbing because of higher demand in the summer. According to the International Air Transport Association’s jet fuel monitor, prices are up 1.4% in just the last week, and about 4% in the last month. Adding to the airlines’ problems is the crisis at Boeing, as well as the less-well-publicized problems with some of the jet engines on planes from rival Airbus. Since an Alaska Airlines Boeing 737 Max jet lost a door plug on a January 5 flight, leaving a gaping hole in the side of the plane 10 minutes after takeoff, the Federal Aviation Administration has limited how many jets Boeing can make over concerns about quality and safety. As a result, airlines have dramatically reduced plans to expand their fleets and replace older planes with more fuel efficient models. In some cases, airlines have asked pilots to take time off without pay, and carriers such as Southwest and United have announced pilot hiring freezes. In addition to the problems at Boeing, hundreds of the Airbus A220 and A320 family of jets globally have also been grounded for at least a month or more to deal with engine problems. Just about all the planes with those engines have been out of sevice for at least a few days to undergo examinations. And Airbus has also cut back the number of planes it expects to deliver to airlines this year because of supply chain problems. Problems for flyers For now, competition in the industry remains fierce: There are 6% more seats available this month compared to July of 2023, according to aviation analytics firm Cirium. And that’s helped to drive fares down — good news for passengers, but more bad news for airlines’ profits. Southwest announced in April that it would stop serving four airports to trim costs — Bellingham International Airport in Washington state, Cozumel International Airport in Mexico, Syracuse Hancock International Airport in New York and Houston’s George Bush Intercontinental Airport. Many more cities lost air service during the financial hard times of the pandemic. While upstart airlines are driving prices lower for travelers, those discount carriers might not survive long term. As the major carriers are making less money, many of the upstarts are flat-out losing money.
Hedge fund Elliott challenges court verdict it lost against LME on nickel
LONDON, July 9 (Reuters) - U.S.-based hedge fund Elliott Associates on Tuesday urged a London court to overturn a verdict supporting the London Metal Exchange's (LME) cancellation of nickel trades partly because the exchange failed to disclose documents. The LME annulled $12 billion in nickel trades in March 2022 when prices shot to records above $100,000 a metric ton in a few hours of chaotic trade. Elliott and market maker Jane Street Global Trading brought a case demanding a combined $472 million in compensation, alleging at a trial in June last year that the 146-year-old exchange had acted unlawfully. London's High Court ruled last November that the LME had the right to cancel the trades because of exceptional circumstances, and was not obligated to consult market players prior to its decision. Lawyers for Elliott told London's Court of Appeal that the LME belatedly released documents in May detailing its "Kill Switch" and "Trade Halt" internal procedures. It also newly disclosed an internal report that Elliott said detailed potential conflicts of interest at the exchange. "It was troubling that one gets disclosure out of the blue in the Court of Appeal for the first time," Elliott lawyer Monica Carss-Frisk told the court. Jane Street Global did not appeal the ruling. "If we had had them (documents) in the proceedings before the divisional court, we may well have sought permission to cross examine." LME lawyers said the new documents were not relevant. "The disclosed documents do not affect the reasoning of the divisional court or the merits of the arguments on appeal," the exchange said in documents prepared for the appeal hearing. "Elliott's appeal is largely a repetition of the arguments which were advanced, and rightly rejected." The LME said it had both the power and a duty to unwind the trades because a record $20 billion in margin calls could have led to at least seven clearing members defaulting, systemic risk and a potential "death spiral". Elliott said the ruling diluted protection provided by the Human Rights Act and also wrongly concluded the LME had the power to cancel the trades.
Sparkling box office for Spring Festival films indicates tremendous potential for movie consumption in Chinese society
According to Chinese movie ticketing platform Taopiaopiao, the box office for the 2024 Spring Festival holidays surpassed last year's 6.766 billion yuan and entered the top two in the history of Chinese Spring Festival holidays box office. I recently watched three movies, and I think they are all good. However, their overall level is not higher than the movies from last Spring Festival holidays. The higher box office compared to last year reflects the strong potential for movie consumption in Chinese society. Our filmmakers need to make further efforts. The current development of Chinese movies has many advantages. People often complain that our film creation faces various "restricted areas," but in terms of societal topics, the space for Chinese film creation is relatively large and relaxed. For example, Zhang Yimou's film Article 20 shows protest scenes and boldly explores the issue of judicial injustice in depth. A few years ago, the film I Am Not Madame Bovary specifically discussed the sensitive issue of petitioning. Another film, Johnny Keep Walking! which was aired last year, also touches on serious social issues. The breadth and depth of these films' topics lay the foundation for their attractiveness. The improvement of China's basic film production level has played a role in boosting their success, resulting in Hollywood films being collectively pushed off the Chinese box office charts. Now, almost any domestic film can be considered "watchable." The next step is to produce world-class masterpieces and promote the collective advancement of Chinese films on the global stage. The three movies that I watched are YOLO, directed, written and starring Jia Ling, a representative of the new generation of female Chinese directors, Pegasus 2, directed by Han Han and Article 20. They are all realistic-themed films, and the actors who play the main characters have some overlap. Although each of them is good, as mentioned earlier, I personally feel that their overall quality is not as good as films screened during last year's Spring Festival holidays. So I have a feeling that Chinese movies have been spinning in place for a year in such a good market environment. Of course, I am not an expert, so what I say may not be correct, or it may be biased. The production level of Chinese films, in terms of technology, has caught up. Domestic films have surpassed Hollywood in the domestic market through competition, which is a great achievement. However, I hope that this does not mark the beginning of a "decoupling" between Chinese movies and the rest of the world, but rather a turning point for Chinese films to reach a higher level domestically and to go global. This requires Chinese realistic films to not only be loved by domestic audiences but also become increasingly "understandable" to foreigners, allowing them to empathize with us through these films. If Chinese films can gradually go global through market-oriented approaches, it will be a new process for the international community to re-recognize and understand China, and to establish common values between us. The earliest understanding of the US by the Chinese people came entirely from the shaping of news propaganda. Later, American films and TV works entered China, showcasing the rich American society. Now, Western media's portrayal of China is completely stereotyped. If Chinese films and other popular culture do not go global, and if a large number of secular elements from China do not appear on the global internet, the outside world's perception of China is likely to be dictated by Western media for a long time. So I hope that China's excellent film market can incubate outstanding works that are loved and enjoyed globally. Not only should our cultural policies provide greater space, but our internet public opinion should also be more tolerant of the interweaving and mutually influencing between Chinese and Western cultural elements. We should not restrict those elements in Chinese films that can resonate with both Chinese and foreign audiences. For example, comedies should not only make Chinese people laugh, but also be understandable to foreigners. Chinese films need to establish their own big stars, including top-tier female stars. In the past, Bruce Lee and Jackie Chan became famous in the West, but they were primarily seen as "Hollywood stars." It is a more challenging journey for Chinese stars to gain international recognition through their own films. The success of Chinese films and Chinese stars worldwide is definitely a complementary process. The backgrounds of our film stories should also be carefully selected and more diverse, enhancing the visual quality and international appeal of the films. Feng Xiaogang's film Be There or Be Square was entirely set in the US, and later, there was another film called Lost in Thailand, both of which achieved good results. Choosing such backgrounds should be encouraged as one of the approaches. In conclusion, I am delighted by the comprehensive recovery of the Chinese film market, and I also hope that the films nurtured by this market will continue to progress. To achieve this, we need to keep introducing the world's best films and collaboratively cultivate the aesthetic taste of the Chinese people alongside Chinese films. Chinese films have already stood up, but they should not monopolize this vast market. Instead, the Chinese market should serve as the stage for them to expand globally.
