OpenAI Releases GPT-6.1 Sol: Near-Astra Coding and Computer Use at One-Fifth of Astra’s Token Price
GPT-6.1 Sol hits near-Astra performance at one-fifth the token cost. Available now through API and ChatGPT Work.
Why it matters
OpenAI's incremental upgrade to GPT-6 Sol closes the gap to its flagship Astra model on agentic coding and computer use while undercutting it sharply on price ($2 input, $10 output per M tokens vs. Astra's $10/$50). Practitioners deploying agents and computer-use workflows can now choose between capability parity at lower cost or reserve Astra for edge cases.
