OpenAI introduces GPT-6.1 Terra for lower-cost computer work

OpenAI introduced GPT-6.1 Terra on Monday, positioning it as a lower-cost model for visual reasoning, computer use and everyday writing. The model is available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, as well as through the API as gpt-6.1-terra. Standard API rates are $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens—half the rates for GPT-5.6 Terra and GPT-6.1 Sol. The model overview lists computer use as a supported tool through the Responses API.
