GPT-6.1 Sol
OpenAI's September 29, 2026 DevDay model and an upgrade to GPT-6 Sol, priced at $2 input and $10 output per million tokens with cached input at $0.10 (95% off standard input, and half of GPT-6 Sol's cache price). It accepts text and image input, provides a 1.05M-token context window and up to 128K output, and supports reasoning effort from low to maximum. OpenAI positions it as "near-Astra intelligence for a fifth of the price": it matches GPT-6 Astra on DeepSWE v1.1 at roughly a fifth of the cost, comes within 2.1 points of Astra on OSWorld 2.0 computer use, and scores 2.2 points above Claude Opus 5.5 on AutomationBench. Available in ChatGPT Work, Codex and the API (as gpt-6.1-sol), but not yet in the main ChatGPT chat. Artificial Analysis has not yet published an Intelligence Index for it, so these are vendor figures.
