What is GPT-6.1 Terra?
GPT-6.1 Terra is an OpenAI model that accepts text and images and returns text. Its documented tasks include interpreting technical drawings, matching product photos with catalog entries, understanding application screens and revising written material.
OpenAI recommends considering Terra for concise writing from supplied material, computer tasks with defined outcomes and scoped code fixes. Developers can integrate it through the API; eligible subscribers can also select it in ChatGPT Work and Codex.

GPT-6.1 Terra pricing
