On October 26, 2026, OpenAI launched the GPT-6.1 Terra model, presented as a fast and efficient option within the GPT-6 family. According to the company itself, it is designed for tasks such as visual reasoning, precise computer use, and clear, natural writing, rather than being the most powerful model in the range on every front.
Terra is available in ChatGPT Work and Codex, as well as via the API under the identifier gpt-6.1-terra, but it is not available in the Chat experience. The rollout covers the Plus, Pro, Business, Enterprise, and Edu plans, within the general usage limits of each plan, and it is selected from the model list.
In the API, its standard price is $1 per million input tokens, $0.05 per million cached input tokens, and $5 per million output tokens. That combination positions it as a daily work tool for a high volume of professional tasks, leaving the higher-capacity models for more complex research or development.
