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."
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.
China will reach climate goal while West falls short
There has been constant low-level sniping in the West against China's record on climate change, in particular its expansion of coal mining, and its target of 2060 rather than 2050 for carbon zero. I have viewed this with mild if irritated amusement, because when it comes to results, then China, we can be sure, will deliver and most Western countries will fall short, probably well short. It is now becoming clear, however, that we will not have to wait much longer to judge their relative performances. The answer is already near at hand. We now know that in 2023 China's share of renewable energy capacity reached about 50 percent of its total energy capacity. China is on track to shatter its target of installing 1200GW of solar and wind energy capacity by 2030, five years ahead of schedule. And international experts are forecasting that China's target of reaching peak CO2 emissions by 2030 will probably be achieved ahead of schedule, perhaps even by a matter of years. Hitherto, China has advisedly spoken with a quiet voice about its climate targets, sensitive to the fact that it has become by far the world's largest CO2 emitter and aware that its own targets constituted a huge challenge. Now, however, it looks as if China's voice on global warming will carry an authority that no other nation will be able to compete with. There is another angle to this. China is by far the biggest producer of green tech, notably EVs, and renewable energy, namely solar photovoltaics and wind energy. Increasingly China will be able to export these at steadily reducing prices to the rest of the world. The process has already begun. It leaves the West with what it already sees as a tricky problem. How can it become dependent on China for the supply of these crucial elements of a carbon-free economy when it is seeking to de-risk (EU) or decouple (US) its supply chains from China? Climate change poses the greatest risk to humanity of all the issues we face today. There are growing fears that the 1.5-degree Celsius target for global warming will not be met. 2023 was the hottest year ever recorded. Few people are now unaware of the grave threat global warming poses to humanity. This requires the whole world to make common cause and accept this as our overarching priority. Alas, the EU is already talking about introducing tariffs to make Chinese EVs more expensive. And it is making the same kind of noises about Chinese solar panels. The problem is this. Whether Europe likes it or not, it needs a plentiful supply of Chinese EVs and solar panels if it is to reduce its carbon emissions at the speed that the climate crisis requires. According to the International Energy Authority, China "deployed as much solar capacity last year as the entire world did in 2022 and is expected to add nearly four times more than the EU and five times more than the US from 2023-28." The IEA adds, "two-thirds of global wind manufacturing expansion planned for 2025 will occur in China, primarily for its domestic market." In other words, willy-nilly, the West desperately needs China's green tech products. Knee-jerk protectionism demeans Europe; it is a petty and narrow-minded response to the greatest crisis humanity has ever faced. Instead of seeking to resist or obstruct Chinese green imports, it should cooperate with China and eagerly embrace its products. As a recent Financial Times editorial stated: "Beijing's green advances should be seen as positive for China, and for the world." The climate crisis is now in the process of transforming the global political debate. Hitherto it seemed relatively disconnected. That period is coming to an end. China's dramatic breakthrough in new green technologies is offering hope not just to China, but to the whole world, because China will increasingly be able to supply both the developed and developing world with the green technology needed to meet their global targets. Or, to put it another way, it looks very much as if China's economic and technological prowess will play a crucial role in the global fight against climate change. We should not be under any illusion about the kind of challenge humanity faces. We are now required to change the source of energy that powers our societies and economies. This is not new. It has happened before. But previously it was always a consequence of scientific and technological discoveries. Never before has humanity been required to make a conscious decision that, to ensure its own survival, it must adopt new sources of energy. Such an unprecedented challenge will fundamentally transform our economies, societies, cultures, technologies, and the way we live our lives. It will also change the nature of geopolitics. The latter will operate according to a different paradigm, different choices, and different priorities. The process may have barely started, but it is beginning with a vengeance. Can the world rise to the challenge, or will it prioritize petty bickering over the vision needed to save humanity? On the front line, mundane as it might sound, are EVs, wind power, and solar photovoltaics.

Iran's president-elect reaffirms policy toward Israel
Iran's President-elect Masoud Pezeshkian reiterated Iran's anti-Israel stance on Monday, saying resistance movements across the region will not allow Israel's "criminal policies" against Palestinians to continue. Pezeshkian told Hassan Nasrallah, the leader of Iran-backed Lebanese Hezbollah, that "the Islamic Republic will always support the people of the region in their resistance against the illegal Zionist regime." This suggests that the incoming government will not change its regional policy under the relatively moderate Pezeshkian, who defeated his hard-line opponent in a runoff election last week. Pezeshkian was quoted as saying by Iranian media, "I am sure that the regional resistance movement will not allow this regime to continue its militant and criminal policies against the oppressed people of Palestine and other countries in the region." The Shiite Muslim Hezbollah and the Palestinian Sunni Muslim Hamas are both part of the local "resistance axis" faction organization supported by Iran. Israel did not immediately comment on Pezeshkian's speech. Hamas led an attack on southern Israel on October 7. According to Israeli statistics, Hamas killed 1,200 people and kidnapped about 250 hostages, triggering the Israeli-Palestinian war. The Gaza Health Ministry said that the Israeli military attack killed more than 38,000 Palestinians and injured nearly 88,000 people.
"Pictures on the wall were falling," New Yorkers rattled by earthquake
An earthquake jolted New York City on Friday morning, followed by more than 10 aftershocks which shook New Jersey, sending tremors as far as Philadelphia to Boston and jolting buildings in Manhattan and throughout its five boroughs. The preliminary quake, measuring 4.8 magnitude, centered around Lebanon, New Jersey, approximately 60 kilometers from New York City, with a depth of about 5 kilometers. Following the earthquake, New York City mayor Eric Adams stated at a press conference that no injuries had been reported, but they would continue to monitor and inspect critical infrastructure. The densely populated New York City was caught off guard by the unusual event. Broadcaster CBS reported that New York had not experienced an earthquake of this magnitude since 1884. Residents in Brooklyn expressed their shock when experiencing tremors which shook the city. "At first, I thought it was just construction next door, but then I noticed the pictures on the wall had fallen," Jennifer Wu, a resident in New York, told the Global Times on Saturday. Video footage circulating online showed the Statue of Liberty and the New York City skyline trembling as the earthquake struck. An angle from directly above Lady Liberty caught Ellis Island shaking during the incident. "It is fine," New York's famous Empire State Building posted on social platform X after the earthquake. The United Nations headquarters located in New York was hosting a Security Council meeting on the Israeli-Palestinian issue, and diplomats present in the meeting felt the tremors, local media reported. According to the Weather Channel, residents in Baltimore, Philadelphia, New Jersey, Connecticut, Boston and other areas of the Northeast seaboard also reported shaking. Tremors lasting for several seconds were felt over 200 miles away near the Massachusetts-New Hampshire border. The New York mayor told the press that New Yorkers should go about their normal day, while the governor Kathy Hochul emphasized the seriousness of the situation. She initiated assessments for damage across the state and had discussions with New Jersey Governor Phil Murphy. The quake caused flight delays throughout the New York area, with temporary control measures put in place across New York's John F. Kennedy International Airport, Newark Liberty International Airport in Newark, New Jersey, and Baltimore-Washington's Thurgood Marshall International Airport, checking for damage to runways. Operations resumed around Friday noon, ABC reported.
