# OpenAI releases GPT-6.1 Terra, a cheaper fast model for computer use, in ChatGPT Work, Codex and the API

## Retrieval answer

OpenAI has introduced GPT-6.1 Terra, a model positioned for visual reasoning, computer use, and writing tasks.

OpenAI has introduced GPT-6.1 Terra, a model positioned for visual reasoning, computer use, and writing tasks. It is available now to Plus, Pro, Enterprise, and Edu users in ChatGPT Work and Codex, and through the OpenAI 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. OpenAI says these prices are 50% below GPT-5.6 Terra and GPT-6.1 Sol. The company says the same ChatGPT Work and Codex usage allowance covers more tasks with Terra than with GPT-5.6 Terra.

OpenAI reports a 15-percentage-point gain over GPT-5.6 Terra on Agents' Last Exam at medium reasoning effort, at about one-third the cost. It also reports a 50.3% score on Terminal-Bench 4.0 at maximum reasoning effort, compared with GPT-5.6 Terra's published 21.5% score. These are OpenAI-reported evaluations; the announcement does not establish independent benchmark replication, real-world task completion rates, or the exact usage allowance for each plan.
