Model scores 15 points above GPT-5.6 Terra at one-third the cost
New model
OpenAI has launched GPT-6.1 Terra, a fast model that combines detailed visual reasoning, precise computer use and clearer writing, and says it is a major step up from GPT-5.6 Terra.
- On Agents' Last Exam, OpenAI reports that Terra at medium reasoning scores 15 percentage points above GPT-5.6 Terra at about one-third the cost, while matching GPT-6 Astra at one-tenth the price per token.
- At maximum effort, OpenAI says Terra is over three times as token efficient as Claude Opus 5.5 and one-fourth its price per token, producing about nine times lower cost per task.
- On OpenAI's internal error-inducing prompt benchmark, Terra's low-effort error rate fell to 16.7% from 53.6% for GPT-5.6 Terra, and at maximum effort it reached 4.3%.
- OpenAI says Terra reaches the Critical cybersecurity threshold under its Preparedness Framework and retains GPT-6 Astra protections, and a system card accompanies the release.
- GPT-6.1 Terra is now available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, with the API model ID gpt-6.1-terra.
- Standard pricing is $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens, 50% below GPT-5.6 Terra and GPT-6.1 Sol.
