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.

Insurers fret over militant attacks, AI hacks at Paris Olympics

LONDON, July 5 (Reuters) - Insurers are nervous that militant attacks or AI-generated fake images could derail the Paris Olympics, risking event cancellations and millions of dollars in claims. Insurers faced losses after the 2020 Tokyo Olympics were postponed for a year due to the COVID-19 pandemic. Since then, wars in Ukraine and Gaza and a spate of elections this year, including in France, have driven up fears of politically-motivated violence at high-profile global events. The Olympics take place in Paris from July 26-Aug 11 and the Paralympics from Aug 28-Sept 8. German insurer Allianz (ALVG.DE), opens new tab is insurance partner for the Games. Other insurers, such as the Lloyd's of London (SOLYD.UL) market, are also providing cover. "We are all aware of the geopolitical situation the world is in," said Eike Buergel, head of Allianz's Olympic and Paralympic programme. "We are convinced that the IOC (International Olympic Committee), Paris 2024 and the national organising committees, together with the French authorities, are taking the right measures when it comes to challenges on the ground."

Nvidia H20 will sell 1 million units this year, contributing $12 billion in revenue!

Recently, according to the FT, citing the latest forecast data of the market research institute SemiAnalysis, AI chip giant NVIDIA will ship more than 1 million new NVIDIA H20 acceleration chips to the Chinese market this year, and it is expected that the cost of each chip is between $12,000 and $13,000. This is expected to generate more than $12 billion in revenue for Nvidia. Affected by the United States export control policy, Nvidia's advanced AI chip exports to China have been restricted, H20 is Nvidia based on H100 specifically for the Chinese market to launch the three "castration version" GPU among the strongest performance, but its AI performance is only less than 15% of H100, some performance is even less than the domestic Ascend 910B. When Nvidia launched the new H20 in the spring of this year, there were reports that due to the large castration of H20 performance, coupled with the high price, Chinese customers' interest in buying is insufficient, and they will turn more to choose China's domestic AI chips. Then there are rumors that Nvidia has lowered the price of the H20 in order to improve its competitiveness. However, the latest news shows that due to supply issues caused by the low yield of the Ascend 910B chip, Chinese manufacturers in the absence of supply and other better options, Nvidia H20 has started to attract new purchases from Chinese tech giants such as Baidu, Alibaba, Tencent and Bytedance. Analysts at both Morgan Stanley and SemiAnalysis said the H20 chip is now being shipped in bulk and is popular with Chinese customers, despite its performance degradation compared to chips Nvidia sells in the United States.

Workers warn of additional walkouts unless demands are met

Members of the National Samsung Electronics Union stage a rally near the company's Hwaseong Campus in Gyeonggi Province, Monday, beginning a three-day strike. Korea Times photo by Shim Hyun-chul By Nam Hyun-woo The biggest labor union at Samsung Electronics initiated a three-day strike on Monday, threatening to disrupt the company's chip manufacturing lines unless management agrees to a wage hike and higher incentives. This marks the first strike by unionized workers in the tech giant's 55-year history. The National Samsung Electronics Union (NSEU) claimed that about 4,000 unionized workers from Samsung's plants nationwide participated in a rally at the company's Hwaseong Campus in Gyeonggi Province. Police estimated that approximately 3,000 union members were present at the rally. According to its own survey, the union reported that a total of 6,540 members expressed their intention to participate in the strike. They emphasized that disruptions in manufacturing are anticipated, with over 5,000 members from facility, manufacturing, and development divisions joining the strike. The comments seem to address market expectations that the walkout is unlikely to cause significant disruptions in the chipmaker's operations, largely because most manufacturing lines are automated. The union said that it may launch another strike for an undetermined period, unless management responds to the union’s demand. Since January, the union has been pressing management for a higher wage increase rate for all members, fulfillment of promises regarding paid leave, and improvements to incentive criteria. With negotiations at an impasse, the union announced on May 29 that it would launch a strike. The NSEU has some 30,000 members, accounting for 24 percent of all Samsung employees. Among the union members, about 80 percent work at the device solutions division, which manufactures semiconductors.
