OpenAI released GPT-6.1 Terra on October 26, 2026, a medium-sized model built to do computer work: it sees what’s on screen and acts across apps, drafting proposals, reading technical drawings, filling out forms, and editing video. On OpenAI’s Agents Last Exam it scored 15 points higher than its predecessor, matched the flagship Astra model at one-tenth the token cost, and finished tasks over 3x faster. Its guessing rate on OpenAI’s private knowledge test fell from 88% to 38% while accuracy rose. API pricing is $1 input / $5 output per million tokens, half the price of GPT-5.6 Terra. Available now in ChatGPT Work and Codex for Plus, Pro, Enterprise, and Edu users, and via the API as gpt-6.1-terra.
