GPT-6.1 Terra: OpenAI’s computer-use model at half the price
Agent builders get a cheaper computer-use model: gpt-6.1-terra is in the OpenAI API at $1 per million input tokens, $0.05 cached and $5 output. OpenAI announced it on Oct 26, 2026, and says that’s 50% below GPT-5.6 Terra and GPT-6.1 Sol.
It’s also in ChatGPT Work and Codex for Plus, Pro, Enterprise and Edu users.
What changed
GPT-6.1 Terra is OpenAI’s new fast model for computer use and visual reasoning. It was announced on Oct 26, 2026, at a lower per-token price than GPT-5.6 Terra and GPT-6.1 Sol.
What changed
- Model id:
gpt-6.1-terrain the OpenAI API. - Price: standard API pricing is $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens. OpenAI says that’s 50% lower than GPT-5.6 Terra and GPT-6.1 Sol.
- Where: Plus, Pro, Enterprise and Edu users get it in ChatGPT Work and Codex. OpenAI says the same usage allowance covers more tasks than with GPT-5.6 Terra.
- Built for: drafting, reading technical drawings, filling out forms and editing videos, the computer-based tasks OpenAI says fill the workday.
OpenAI’s own numbers
- On Terminal-Bench, at max reasoning effort, OpenAI reports Terra solves 50.3% of tasks, against GPT-5.6 Terra’s published 21.5%.
- For the most complex coding tasks, OpenAI still points to GPT-6.1 Sol and GPT-6 Astra.
- OpenAI says Terra meets the Critical threshold in cybersecurity under its Preparedness Framework and keeps the protections built for GPT-6 Astra.
What to do
- Paying for high-volume computer-use or form-filling runs on GPT-5.6 Terra or GPT-6.1 Sol? It may be worth running a sample of your own tasks on
gpt-6.1-terrabefore you switch, since the benchmark figures come from OpenAI.
