GPT-6.1 Terra

GPT-6.1 Terra is OpenAI's fast, efficient model for visual reasoning, precise computer use and natural writing. It reads what's on screen, takes action across apps, and handles workday tasks like filling out forms, interpreting technical drawings and drafting proposals. OpenAI says it matches GPT-6 Astra on Agents' Last Exam at one tenth the price per token and finishes tasks over 3x faster. Available now in ChatGPT Work and Codex, and in the API as gpt-6.1-terra.
