danielmac8 compiles leaks pointing to an imminent GPT-6 "Astra" launch: the codename returns a 404 in the OpenAI API while other non-existent model names return 400, suggesting it's staged.
Key rumored details:
- Sam Altman claims human parity at computer use at superhuman speeds
- Per @alexeheath, trained for ultra long-horizon tasks with a new 'persistent' reasoning effort
- The Information reports a new 'recurrent depth' reasoning algo that processes data recurrently in Transformer layers, acting like a much larger model
- 4x stronger than GPT-5.6 Sol on an internal ExploitGym benchmark
- Speculation: end-to-end multi-agent orchestration, natively delegating to Luna, Terra and Sol
The author expects the AI model release of the year, a leap comparable to GPT-3 to GPT-4.
