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.

Explainer: How Boeing's Starliner can bring its astronauts back to Earth
WASHINGTON, June 24 (Reuters) - Problems with Boeing's Starliner capsule, still docked at the International Space Station (ISS), have upended the original plans for its return of its two astronauts to Earth, as last-minute fixes and tests draw out a mission crucial to the future of Boeing's (BA.N), opens new tab space division. NASA has rescheduled the planned return three times, and now has no date set for it. Since its June 5 liftoff, the capsule has had five helium leaks, five maneuvering thrusters go dead and a propellant valve fail to close completely, prompting the crew in space and mission managers in Houston to spend more time than expected pursuing fixes mid-mission. Here is an explanation of potential paths forward for Starliner and its veteran NASA astronauts, Barry "Butch" Wilmore and Sunita "Suni" Williams. THE CURRENT SITUATION Starliner can stay docked at the ISS for up to 45 days, according to comments by NASA's commercial crew manager Steve Stich to reporters. But if absolutely necessary, such as if more problems arise that mission officials cannot fix in time, it could stay docked for up to 72 days, relying on various backup systems, according to a person familiar with flight planning. Internally at NASA, Starliner's latest targeted return date is July 6, according to this source, who spoke on condition of anonymity. Such a return date would mean that the mission, originally planned for eight days, instead would last a month. Starliner's expendable propulsion system is part of the craft's "service module." The current problems center on this system, which is needed to back the capsule away from the ISS and position it to dive through Earth's atmosphere. Many of Starliner's thrusters have overheated when fired, and the leaks of helium - used to pressurize the thrusters - appear to be connected to how frequently they are used, according to Stich.
Israeli strike kills 16 at Gaza school, military says it targeted gunmen
CAIRO/GAZA, July 6 (Reuters) - At least 16 people were killed in an Israeli strike on a school sheltering displaced Palestinian families in central Gaza on Saturday, the Palestinian health ministry said, in an attack Israel said had targeted militants. The health ministry said the attack on the school in Al-Nuseirat killed at least 16 people and wounded more than 50. The Israeli military said it took precautions to minimize risk to civilians before it targeted the gunmen who were using the area as a hideout to plan and carry out attacks against soldiers. Hamas denied its fighters were there. At the scene, Ayman al-Atouneh said he saw children among the dead. "We came here running to see the targeted area, we saw bodies of children, in pieces, this is a playground, there was a trampoline here, there were swing-sets, and vendors," he said. Mahmoud Basal, spokesman of the Gaza Civil Emergency Service, said in a statement that the number of dead could rise because many of the wounded were in critical condition. The attack meant no place in the enclave was safe for families who leave their houses to seek shelters, he said. Al-Nuseirat, one of Gaza Strip's eight historic refugee camps, was the site of stepped-up Israeli bombardment on Saturday. An air strike earlier on a house in the camp killed at least 10 people and wounded many others, according to medics. In its daily update of people killed in the nearly nine-month-old war, the Gaza health ministry said Israeli military strikes across the enclave killed at least 29 Palestinians in the past 24 hours and wounded 100 others.
US politicians' lurch to levying high tariffs to damage global economic sustainability
US politicians are advocating for steep tariffs, echoing the protectionist Fordney-McCumber Tariff of 1922. Despite potential international retaliation, risks to global economic rules and a shift from post-World War II principles, US politicians have promised to increase trade barriers against China, causing concerns for the sustainability of global economic harmony. A century ago, the Republican Congress passed the Fordney-McCumber Tariff of 1922. This post-World War-I effort to protect the US from German competition and rescue America's own businesses from falling prices sparked a global wave of tariff hikes. While long forgotten, echoes of Fordney-McCumber now reverberate across the US political landscape. Once again, politicians are grasping the tariff as a magic talisman against its own economic ills and to contain the rise of China. The Democratic Party of the 1920s opposed tariffs, because duties are harmful to consumers and farmers, but today both President Joe Biden and former President Donald Trump favor national delivery through protectionism. Trump promised that his second term, if elected, would impose 60-percent tariffs on everything arriving from China and 10-percent tariffs on imports from the rest of the world, apparently including the imports covered by 14 free trade agreements with America's 20 partners. He initially promised 100-percent tariffs on electric vehicles (EVs), but when Biden declared that he was hiking tariffs on EVs from China to 100-percent, Trump raised the ante to 200-percent. On May 14, 2024, the White House imposed tariffs ranging from 25 percent (on items such as steel, aluminum and lithium batteries) to 50 percent (semiconductors, solar cells, syringes and needles) and 100 percent (electric vehicles) on Chinese imports. US government officials offer "national security" and "supply chain vulnerability" as the justification for levying high tariffs. To deflect worries about inflation, US Trade Representative Katherine Tai declared, "first of all, I think that that link, in terms of tariffs to prices, has been largely debunked." Contrary findings by the United States International Trade Commission and a number of distinguished economists, as well as Biden's own 2019 statement criticizing Trump's tariffs - "Trump doesn't get the basics. He thinks tariffs are being paid by China… [but] the American people are paying his tariffs" - forced Tai's office to wind back her declaration. The fact that prohibitive barriers to imports of solar cells, batteries and EVs will delay the green economy carries zero political weight with Trump and little with Biden. Nor does either of them worry about the prospects of Chinese retaliation and damage to the fabric of global economic rules. Historical lessons - unanticipated consequences of the foolish Fordney-McCumber Tariff of 1922 and the Smoot-Hawley Tariff of 1930 - are seen as irrelevant by the candidates and their advisers. The US' lurch from its post-World War II free trade principles offers China a golden opportunity. On the world stage, China will espouse open free trade and investment. China will encourage EV and battery firms to establish plants in Europe, Brazil, Mexico and elsewhere, essentially daring the US to damage its own alliances by restricting third country imports containing Chinese components. Whether the fabric of global economic rules that has delivered astounding prosperity to the world will survive through the 21st century remains to be seen. Much will depend on the decisions of other large economic powers, not only China but also the European Union and Japan, as well as middle powers, such as Australia, Brazil, Chile, ASEAN and South Korea. Their actions and reactions will reshape the rules of the 21st century. If others follow America down this costly path, the world will become less prosperous and vastly more unpredictable. If they resist, the US risks being diminished and more isolated. The author is a non-resident Senior Fellow at the Peterson Institute of International Economics. bizopinion@globaltimes.com.cn
Gold reaction to employment data and geopolitical events
The June US Nonfarm Payrolls (NFP) data showed an increase of 206,000 jobs, exceeding expectations. Political uncertainty and the People's Bank of China's pause in gold purchases influence gold market dynamics. Recent technical developments in the gold market, including breaking the triangle formation and subsequent rally, indicate the potential for higher prices. Despite a bullish outlook, further consolidation is possible before a significant surge. The recent US Nonfarm Payrolls (NFP) data revealed a rise of 206,000 jobs in June, surpassing the market expectation of 190,000, despite a downward revision from 272,000 to 218,000 for May. The unemployment rate increased to 4.1% and the wage inflation declined to 3.9% year-over-year. These mixed employment signals have increased the likelihood of a rate cut by the Federal Reserve in September. Additionally, political developments in France, where the left-wing New Popular Front led by Jean-Luc Mélenchon is poised to win a significant number of seats, add to the global economic uncertainty. Meanwhile, the People's Bank of China (PBoC) has paused its gold purchasing program, potentially waiting for a further price pullback. These factors collectively influence gold prices, providing a complex backdrop where the prospect of lower interest rates, political uncertainty, and central bank purchasing strategies are likely to drive market dynamics and investor behaviour in the coming months. Bullish Trends in Gold Prices The announcement of the NFP data has dropped the US Dollar Index and boosted gold prices. Since the gold market broke the triangle formation on Wednesday and formed an inside candle on Thursday, the break above Thursday's high on Friday initiated a strong rally, closing the price at higher levels. The red line was the first resistance of this breakout where the gold closed the last week. A clear break above this level may initiate another surge higher. The breakout of the triangle suggests higher prices, but the risk environment remains, as June was a correction month. It looks like the price is preparing for higher levels, but the possibility of consolidation before the surge cannot be ignored. Bottom line In conclusion, the increase in US employment, despite mixed signals in wage inflation and unemployment, has increased the likelihood of a Federal Reserve rate cut, boosting gold prices while weakening the US Dollar Index. Political uncertainties in France and the pause in gold purchases by the People's Bank of China further contribute to the complex economic landscape, indicating potential volatility ahead. The gold market's recent technical developments, including breaking the triangle formation and the subsequent rally, suggest readiness for higher prices. However, the possibility of consolidation before another significant surge remains, necessitating careful observation by investors as the market navigates these multifaceted influences.
"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.
