OpenAI launches GPT-6.1 Terra for precise computer use

OpenAI has launched GPT-6.1 Terra, a fast, efficient model combining detailed visual reasoning, precise computer use, and clearer, more natural writing. OpenAI calls it a major step up from GPT-5.6 Terra and says it excels at proposals, technical drawings, forms, and video editing. 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. OpenAI also says Terra completes tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol.
