OpenAI has introduced GPT-6.1 Terra, a model for visual reasoning, computer-use tasks, writing, and coding. It is available immediately to ChatGPT Work and Codex users on Plus, Pro, Enterprise, and Edu plans, and through the OpenAI API as gpt-6.1-terra. OpenAI lists standard API prices of $1 per million input tokens, $0.05 per million cached input tokens, and $5 per million output tokens; it says these prices are 50% below GPT-5.6 Terra and GPT-6.1 Sol. OpenAI says GPT-6.1 Terra can handle tasks including interpreting technical drawings, entering invoice data into accounting software, completing forms, and editing video. On the Agents’ Last Exam computer-use benchmark at medium reasoning effort, OpenAI reports that Terra scored 15 percentage points above GPT-5.6 Terra at about one-third the cost, while matching GPT-6 Astra’s performance at one-tenth its token price. It says Terra completed tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol. OpenAI reports a lower error rate on its internal error-inducing-prompt benchmark: 16.7% at low reasoning effort, versus 53.6% for GPT-5.6 Terra, and 4.3% at maximum effort. On Terminal-Bench 4.0, Terra solved 50.3% of tasks at maximum reasoning effort, compared with GPT-5.6 Terra’s published 21.5%. OpenAI says the model meets its Critical cybersecurity threshold and retains GPT-6 Astra’s safeguards.
