OpenAI announced GPT-6.1 Terra on Oct 26, 2026 as fast, capable computer use at a lower price, that understands what is on screen, takes action across apps and writes naturally for the workday (post).

At max effort, Terra is claimed to be over 3x more token-efficient than Claude Opus 5.5 and one-fourth its price per token, for roughly 9x lower cost per task (post).

It is also claimed to complete tasks over 3x faster than both GPT-6 Astra and GPT-6.1 Sol (post).

OpenAI separately says it matches GPT-6 Astra at one-tenth the price per token and substantially beats GPT-5.5 Terra predecessor GPT-5.6 Terra on Agents Last Exam (post). Commentators note OpenAI still positions Sol or Astra for complex coding (post.

It is rolling out to Plus, Pro, Enterprise and Edu in ChatGPT Work and Codex, plus API as gpt-6.1-terra (post).
