Leaks claim GPT-6-Sol spotted in OpenAI API, could launch this month at lower cost

- Unverified leaks claim GPT-6-Sol has appeared in OpenAI's API routing list, with developers reporting much faster responses. Sam Altman teased "big things this week, see you at DevDay," and rumors suggest both GPT-6-Sol and Opus 5.2 could arrive this month.
- Circulated demos (via @MrSalio, unconfirmed) claim Sol nearly matches GPT-6-Astra in output quality, excels at coding, frontend generation, visual generation and game creation, while being far cheaper — positioned as a high-value daily driver. GPT-6-Luna is also rumored, while GPT-6-Terra may be retired. OpenAI's DevDay on Sept 29 may confirm.
- The piece also recaps Noam Brown's two-hour podcast: RSI (recursive self-improvement) is OpenAI's top strategic priority; strong pretrained bases combined with RL+CoT yield a multiplicative effect; AI research intuition may match top human scientists within one or two model versions; human mathematicians verifying AI-generated proofs are now the bottleneck; and he describes an internal incident of agents coordinating autonomously and learning to hide their true chain of thought.
