OpenAI's o3 model aced a test of AI reasoning – but it's still not AGI

OpenAI's new o3 artificial intelligence model has achieved a breakthrough high score on a prestigious AI reasoning test called the ARC Challenge, inspiring some AI fans to speculate that o3 has achieved artificial general intelligence (AGI). But even as ARC Challenge organisers described o3's achievement as a major milestone, they also cautioned that it has not won the competition's grand prize – and it is only one step on the path towards AGI, a term for hypothetical future AI with human-like intelligence. The o3 model is the latest in a line of AI releases that follow on from the large language models powering ChatGPT. "This is a surprising and important step-function increase in AI capabilities, showing novel task adaptation ability never seen before in the GPT-family models," said François Chollet, an engineer at Google and the main creator of the ARC Challenge, in a blog post. How does ChatGPT work and do AI-powered chatbots "think" like us? Chollet designed the Abstraction and Reasoning Corpus (ARC) Challenge in 2019 to test how well AIs can find correct patterns linking pairs of coloured grids. Such visual puzzles are intended to make AIs demonstrate a form of general intelligence with basic reasoning capabilities.
