OpenAI releases GPT-6.1 Terra

Availability and evidence

OpenAI’s API changelog dates the release to October 26. The launch announcement makes Terra available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and to developers as gpt-6.1-terra. Standard prices were $1 input, $0.05 cached input and $5 output per million tokens. [1][2]

OpenAI positioned Terra for visual reasoning, computer use and writing, and reported improved coding and factuality over GPT-5.6 Terra. These are vendor evaluations rather than evidence that the model reliably completes every advertised workflow. [1]
