The maker of ChatGPT had made progress on Q* (pronounced Q-Star), which some internally believe could be a breakthrough in the startup’s search for superintelligence, also known as artificial general intelligence (AGI), one of the people told Reuters. OpenAI defines AGI as AI systems that are smarter than humans.

Definitely seems AGI related. Has to do with acing mathematical problems - I can see why a generative AI model that can learn, solve, and then extrapolate mathematical formulae could be a big breakthrough.
