Altman at Dreamforce: an internal model past Astra "can do things that the best mathematicians in the world cannot"
In a Dreamforce 2026 session with Marc Benioff, uploaded to Salesforce's YouTube channel on 2026-09-16, Sam Altman laid out a math ladder: GPT-5.5 "maybe as good as an average math professor," GPT-5.6 "a top one or two percentile math professor," Astra "a little bit better than that," and an unreleased internal model beyond Astra that "can do things that the best mathematicians in the world cannot." The claim is unbenchmarked and self-reported, which is the whole counter-argument, but it is the specific ladder OpenAI is now willing to state on stage. It lands the same week r/singularity is passing around an older forecast that gave a 50% chance of AI solving a Millennium Prize Problem by 2054.
