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.

South African rand stable as markets await US interest rate hints
JOHANNESBURG, July 9 (Reuters) - The South African rand was little changed in early trade on Tuesday, as markets awaited the Federal Reserve chair's testimony in Washington and U.S. June inflation data for clues on the country's future interest rate path. At 0644 GMT, the rand traded at 18.1300 against the dollar , near its previous close of 18.1175. "The rand has opened marginally softer at 18.13 this morning, and we expect trading to remain range-bound in the short term," said Andre Cilliers, currency strategist at TreasuryONE. Markets will listen to the tone of Fed Chair Jerome Powell's testimony in Washington on Tuesday and Wednesday and look to June inflation data out of the U.S. later this week for hints on the future interest rate path in the world's biggest economy. "Analysts will be gauging the Fed's response to the recent softer U.S. economic and labour data, with markets already starting to price in two rate cuts this year," Cilliers added. The risk-sensitive rand often takes cues from global drivers like U.S. economic policy in the absence of major local factors. South Africa's benchmark 2030 government bond was slightly stronger in early deals, with the yield down 1 basis point at 9.74%.
Coexisting and cooperating with China is the only choice for the US
US Secretary of State Antony Blinken declared at the Munich Security Conference: "If you're not at the table in the international system, you're going to be on the menu." The arrogant thinking of American political elites is evident: Whoever does not comply with the US will be excluded from the table of the American-led system and put on the menu. How arrogant. The US is actively pushing for "decoupling" from China and trying to persuade the entire West to "decouple" from China, using the term "de-risking." Washington hopes to ultimately contain China's development in order to maintain American hegemony. However, this time, Washington is facing a historically experienced and strategically rich Eastern civilization. Previous opponents targeted by the US have chosen to confront the US strategically. The US not only has the strongest technological and military capabilities but also controls global financial and information networks with a large number of allies. Those countries that had engaged in direct confrontations had suffered losses. Some of them had disintegrated, some had been weakened, and some had fallen into difficulties. However, what Washington sees from China is strategic composure and resilience. China is now staging an unprecedented and grand "Tai Chi." However, some Chinese people feel that this is not enough: Why can't we confront the US head-on? But I want to say that this is precisely the brilliance of China. This grand "Tai Chi" is about dismantling the pressure the US is putting on China. Europe is different from the US. A European diplomat once said in private that the topic of China has become toxic in the US, but in Europe, it is still possible to openly display friendliness toward China. There is genuine competition between the Europe and China despite Europe leans more toward the US between China and the US. Only in terms of ideology does the term "West" truly exist. In terms of fundamental economic interests, Europe has considerable independence. In terms of security, their attitude toward China also differs greatly from that of the US. In the Asia-Pacific region or China's periphery, the US wants to create an "Asian NATO." The specific situations of countries in dispute with China are very different. China has enormous influence in the region, is the largest trading partner of the vast majority of countries in the region and has friendly relations with most countries in the region. The disputes with countries are not fundamental strategic conflicts, and China has the ability to manage disputes with each specific country and push them to move toward neutrality to varying degrees without being tied to the US' policy toward China. China has a lot of trading partners and stakeholders in the US. The trade volume between China and the US, despite the decline, reached $664.4 billion in 2023, which shows China's huge presence in the US, and is the bond of the two countries in the current situation. The US is not a country where the political elites can have absolute say, and the huge interests have forced the US president and senior officials to repeatedly proclaim that they "don't want to decouple from China" and instead they want to "manage the US-China competition" and see "preventing a war with China" as clearly in everyone's best interest. China should engage in a "strategic battle" with the US at the closest possible distance. We need to maintain friendly relations with certain forces within the US, speed up the resumption of flights between the two countries, increase personnel exchanges and completely reverse the downturn of China-US contacts during the pandemic. In addition to the above dismantling, we also have the huge increment in the "Belt and Road." This initiative will increase China's power to compete with the US, greatly extending the front line that the US needs to maintain in containing China, making the US more powerless. In order to dismantle the US strategy toward China, China must become more diversified while maintaining strategic consistency. Our national diplomacy toward the US is very principled, rational and determined, which is clearly different from other countries targeted by the US. Our public diplomacy toward the US needs to be unique, with both "anti-American voices" and efforts to maintain friendly relations between the two societies and further expand economic and practical cooperation with the US. Just as eagles have their own way of flying and doves have their own formation, just as we see the US as complex, China must also be seen as complex in the eyes of the US. China is both a geopolitical concern and a profitable investment destination for them, and is one of the largest trading partners that is difficult to replace. Some American political elites proclaim China as an "enemy," but it is important to make the majority of Americans feel that China is not. No matter how intense the struggles between China and the US may be, we cannot shape the entire US toward an enemy direction. China has to make the US political elites recognize that it is futile to deal with China in the same way as it historically dealt with the Soviet Union and other major powers. Furthermore, willingly or unwillingly, coexistence and cooperation with China will be their only choice.
It may be getting harder to leave your smart wearable for the sake of your health
The world's first portable electrocardiograph was an 85-pound backpack, and now a 10-gram patch attached to your chest can transmit electrocardiograms uninterrupted for two weeks. The Apple Watch, which is worn by an estimated 100 million people, can send a text message to alert people when their heartbeat is irregular. Wearable sensors on the arms, wrists and fingers can now report arrhythmias, blood sugar levels, blood oxygen and other health indicators. Medical journals have also proposed a more ambitious vision - wearable devices can monitor patients with chronic diseases, eliminating the need for frequent hospital visits. They can spot potential health problems before a stroke or diabetes develops. The forces of health technology and wearables are converging. Tech giants like Apple (AAPL) and Alphabet's (GOOGL) Google are adding health features to their products. Medical technologists like electrocardiogram patch maker iRhythm Technologies or blood sugar monitor makers DexCom (DXCM) and Abbott Laboratories (ABT) are taking their devices beyond the clinic. "In the sensor world, people started on the consumer side and wanted to get into health care," said Kevin Sayer, chief executive of Decon Medical. "In health care, we're trying to be more consumer oriented, and I think all of those things are sort of colliding." Early bets favored the tech giants, with every health-related announcement from Apple, Google or Samsung Electronics hitting medical tech stocks. But changing doctors' practices will also require sustained investment in clinical trials. Big tech companies have cut back on investments in health care. Now it seems that medical technologists will be at the vanguard of the digital health revolution - with smartwatches and smart rings bringing them more customers who need to be diagnosed. Blake Goodner, co-founder of Bridger Management, a hedge fund focused on health care, said: "A group of medtech companies focused on digital health are maturing and reaching a scale where they can not only be profitable but also make investments to compete with larger tech companies." Tech giants aren't getting out of the health business. Apple's smartwatch has an electronic heart rate sensor that generates a single-point electrocardiogram, a wrist temperature sensor, and an accelerometer that can detect violent falls. Hundreds of millions of people are wearing smartwatches with health features from Apple or its rivals Samsung and Garmin.
Boeing will be fined 3.5 billion yuan for "conspiracy to defraud" in two air crashes. Will the company slide into the abyss?
Taking the initiative to plead guilty to Boeing is not small, but it can avoid being exposed to more problems when it is publicly tried, which is a "minor penalty" for Boeing. So now the families of the crash victims are very opposed to the move, demanding that the trial continue to be open. But after all, Boeing is America's oldest industrial son, whether it is Trump or Biden, and finally have to gently put down, give a chance. The Justice Department had been seeking a guilty plea from Boeing as early as May, when it launched the investigation. After all, if you plead guilty, you only need to pay a fine, and if you really go to court, you don't know how many quality problems Boeing will be exposed by your witnesses. Boeing also knew it had too many flaws, and paying a $243.6 million fine and bringing in a third party to monitor its compliance for three years, totaling more than $400 million in additional expenses, is small change for Boeing. Given Boeing's style in the past few years, this fine may not even force Boeing to tighten production line management. Just this kind of "reconciliation" that completely excludes the victims of the crash can not get the families to agree. Paul Cassell, an attorney for the victims' families, said he plans to ask the federal judge overseeing the case to reject the agreement and "hold this case to an open trial so that all the facts of this case can be presented in a fair and public manner before a jury." The demand is reasonable, but the US judge will most likely side with Boeing.
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.
