GPT-6.1 Sol

OpenAI's latest GPT-6 workhorse — near-Astra coding at Sol cost.

GPT-6.1 Sol is the upgrade to GPT-6 Sol, released at OpenAI DevDay 2026: OpenAI's model for complex coding, computer use and professional work, close to GPT-6 Astra on agentic-coding benchmarks at a fifth of Astra's vendor price. Long autonomous sessions, reliable tool calling and reasoning effort up to max. The new default for most Codex work; reach for Astra when the task is unusually hard.
