China’s AI industry has almost caught up with America’s

THE WORLD’s first “reasoning model”, an advanced form of artificial intelligence, was released in September by OpenAI, an American firm. o1, as it is called, uses a “chain of thought” to answer difficult questions in science and mathematics, breaking down problems to their constituent steps and testing various approaches to the task behind the scenes before presenting a conclusion to the user. Its unveiling set off a race to copy this method. Google came up with a reasoning model called “Gemini Flash Thinking” in December. OpenAI responded with o3, an update of o1, a few days later.
