OpenAI's GPT-6.1 Terra Lands in ChatGPT Work, Codex and the API: What Changes
OpenAI's GPT-6.1 Terra is rolling out in ChatGPT Work and Codex and is also available in the API as gpt-6.1-terra, a fast, efficient model built for visual reasoning, precise computer use, and clear, natural writing. The rollout covers Plus, Pro, Business, Enterprise, and Edu plans, but Terra is only available in Work and Codex, not in ChatGPT's regular Chat experience, and it does not support UAE inference residency.

What Is GPT-6.1 Terra, and Where Does It Show Up?
GPT-6.1 Terra is rolling out in ChatGPT Work and Codex, and OpenAI has also released it in the API as gpt-6.1-terra, which the company describes as a fast, efficient model for visual reasoning, precise computer use, and clear, natural writing. [1]
Terra is available in Work and Codex, not in ChatGPT's regular Chat experience. [1]
Which ChatGPT Plans Get GPT-6.1 Terra?
The rollout includes Plus, Pro, Business, Enterprise, and Edu plans. As it reaches an account, users can select GPT-6.1 Terra from the model list in Work or Codex, and the plan's overall usage limits stay unchanged. [1]
Some Plus and Pro users may see GPT-6.1 Terra set at Medium instead of GPT-6.1 Sol at Light in the default Power presets in Work. Standard and Fast modes are supported where available. [1]
| Option or question | What to know |
|---|---|
| Plus / Pro | Included in the Terra rollout; GPT-6.1 Terra appears in the model list once it reaches the account. Some Plus and Pro users may see Terra set at Medium instead of GPT-6.1 Sol at Light in the default Power presets in Work. [1] |
| Business | As the rollout reaches a Business workspace, members can use Terra in Work and Codex with the same default Power presets and overall plan limits as before. [1] |
| Enterprise / Edu | Members can use Terra once they have permission to use both the model and Work or Codex; workspace owners and admins can review model-access settings and assigned roles. [1] |
Where GPT-6.1 Terra Isn't Available Yet
GPT-6.1 Terra does not support UAE inference residency. OpenAI specifies that this restriction is based on where inference runs, not on the user's own location. [1]
Because the rollout is staged by plan and workspace, GPT-6.1 Terra may not appear in a given account's model list immediately even on an eligible plan. [1]
How to Start Using GPT-6.1 Terra
Access depends on plan, workspace rollout stage, and (for Enterprise/Edu) permissions, so the steps differ slightly by account type. [1]
- Open ChatGPT Work or Codex and check the model list for GPT-6.1 Terra; it appears once the rollout reaches your account or workspace. [1]
- On Enterprise or Edu, ask a workspace owner or admin to confirm you have permission to use both the Terra model and Work or Codex. [1]
- Developers can call the model directly through the API using the model id gpt-6.1-terra. [1]
