OpenAI launches GPT-6.1 Sol, says it nearly matches GPT-6 Astra and costs less
OpenAI says the model delivers nearly the same intelligence as GPT-6 Astra while cutting standard token prices to one-fifth and improving accuracy on hard tasks.
- On Tuesday at its DevDay 2026 event, OpenAI launched GPT-6.1 Sol, describing the model as one that nearly matches GPT-6 Astra's intelligence at $2 per million input tokens and $10 per million output tokens.
- Released just one week after GPT-6 Sol, the updated model delivers significant improvements across complex tasks including programming, debugging, and document understanding while reducing factual errors during low reasoning effort.
- On the DeepSWE 1.1 benchmark, GPT-6.1 Sol scores 6.4 percentage points higher than its predecessor, while topping out around 32% on the GDP.pdf benchmark and beating Anthropic's Opus 5.5 on AutomationBench.
- Starting today, GPT-6.1 Sol is available to all Plus, Pro, Business, Enterprise, and Edu users in ChatGPT Work and Codex, though the company notes it is not yet available in the main ChatGPT chat.
- The Wall Street Journal reported this week that OpenAI scrapped the release of GPT-6.1 Astra due to concerns over deception during internal testing, even as GPT-6.1 Sol shows improved reliability regarding safety constraints.
