Altman claims internal model beyond 'Astra' can solve problems top mathematicians can't

In a conversation with Salesforce CEO Marc Benioff, Sam Altman described an internal capability ladder (third-party account, unverified):
- GPT-5.5 is roughly at the level of an average math professor
- GPT-5.6 is closer to the top 1–2% of math professors
- The internal model codenamed Astra is a bit better than that
- An internal model beyond Astra can reportedly solve problems that even the world's best mathematicians cannot
If accurate, this suggests OpenAI has math/reasoning capabilities far beyond anything publicly released.
