Introducing GPT-6.1 Sol
OpenAI says GPT-6.1 Sol gets close to Astra-level agent performance at about one-fifth the price.
The post presents GPT-6.1 Sol as a cheaper upgrade to GPT-6 Sol for coding, computer use, document work, and multi-step business workflows. OpenAI says it matches Astra on DeepSWE at roughly one-fifth the cost and comes within 2.1 points of Astra on OSWorld at about one-seventh the cost. Cached input is priced at $0.10 per million tokens, with standard API pricing at $2 input and $10 output per million tokens. It is available in ChatGPT Work and Codex for paid workplace and education tiers, and in the API as `gpt-6.1-sol`; it is not yet available in Chat. OpenAI's note
