OpenAI releases GPT-6.1 Terra, a faster, cheaper model for computer use and everyday work
OpenAI introduced GPT-6.1 Terra, a fast, lower-cost model focused on visual reasoning, computer use and natural writing, available in ChatGPT Work, Codex and the API at $1 per million input tokens and $5 per million output tokens.
What happened
- On October 26, 2026, OpenAI introduced GPT-6.1 Terra as the successor to GPT-5.6 Terra, aimed at workday tasks such as drafting proposals, reading technical drawings, filling out forms and editing videos.
- It is available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and to developers through the API as gpt-6.1-terra.
- Standard API pricing is $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens, which OpenAI says is 50% lower than GPT-5.6 Terra and GPT-6.1 Sol.
- OpenAI reports it scores 15 points higher than GPT-5.6 Terra on its Agents' Last Exam computer-use benchmark at medium effort, and more than doubles GPT-5.6 Terra on Terminal-Bench 4.0 (50.3% vs 21.5%), while recommending GPT-6.1 Sol or GPT-6 Astra for the hardest coding work.
- AWS made GPT-6.1 Terra generally available on Amazon Bedrock the same day, with up to 1 million input tokens of context and text and image inputs.
Why it matters: Cheaper, faster computer-use models make it more practical for small businesses to automate routine screen work, such as entering invoice details into accounting software, though the benchmark gains are OpenAI's own figures.
