OpenAI GPT-6.1 Terra: Availability, Computer Use, and API Pricing
OpenAI began rolling out GPT-6.1 Terra on October 26 in ChatGPT Work and Codex, with the API model identifier `gpt-6.1-terra`. ChatGPT rollout includes Plus, Pro, Business, Enterprise, and Edu, with access depending on plan, region, workspace settings, and rollout timing. For requests up to 272K input tokens, standard API rates are $1 per million input tokens, $0.05 per million cached input tokens, and $5 per million output tokens; long-context, Fast-mode, and cache-write rates differ.
OpenAI began rolling out GPT-6.1 Terra on October 26, 2026, in ChatGPT Work and Codex, with the API model identifier gpt-6.1-terra. For ChatGPT, access depends on plan, region, workspace settings, and when the rollout reaches an account. OpenAI describes Terra as a fast model for visual reasoning, computer use, and natural writing, and says its pricing makes automating high-volume work practical for developers.

What GPT-6.1 Terra is built for
OpenAI describes Terra as a fast, efficient model combining detailed visual reasoning and precise computer use with clearer, more natural writing. The announcement frames its examples as communication and computer-based work tasks, including drafting proposals, interpreting technical drawings, filling forms, editing videos, and reading incoming invoices to enter their details into accounting software.

OpenAI reports that, at medium reasoning effort, GPT-6.1 Terra performs on par with GPT-6 Astra on Agents’ Last Exam at one-tenth GPT-6 Astra’s price per token. The vendor also says Terra completes tasks over three times faster than GPT-6 Astra and GPT-6.1 Sol. These are vendor-reported benchmark results. OpenAI says GPT-6.1 Sol and GPT-6 Astra remain the better choices for its most complex coding tasks. (OpenAI benchmark and model comparisons)

| Mode | Context | Input | Cached input | 30m cache write | 12h cache write | Output |
|---|---|---|---|---|---|---|
| Standard | Short (≤272K input tokens) | $1.00 | $0.05 | $1.25 | $2.50 | $5.00 |
| Standard | Long (>272K input tokens) | $2.00 | $0.10 | $2.50 | $5.00 | $7.50 |
| Fast | Short (≤272K input tokens) | $2.00 | $0.10 | $2.50 | $5.00 | $10.00 |
| Fast | Long (>272K input tokens) | $4.00 | $0.20 | $5.00 | $10.00 | $15.00 |
OpenAI also lists separate fees for certain tool calls and a regional-processing uplift for eligible models. Check the OpenAI API pricing page for the current rates and conditions. (OpenAI API pricing)
The release notes add an inference-residency caveat: GPT-6.1 Terra does not support UAE inference residency. OpenAI says this restriction is based on where inference runs, not the user's location. (OpenAI model release notes)
