Terra moves to GPT-6.1
When OpenAI introduced the Sol and Luna versions of its GPT-6 family last month, the mid-tier Terra model was left out of the update. The company has now moved Terra from GPT-5.6 to GPT-6.1 and made it available in both ChatGPT and Codex.
Highlights
- Speed: OpenAI says the new Terra responds faster than the previous model.
- Computer use: The model's ability to operate screens and interfaces has been improved.
- Price: The update is offered at a lower cost.
Why it matters
Terra sits between Sol and Luna in OpenAI's model lineup. Updating this segment means more capable AI at a more affordable price for everyday use. The Codex integration shows the new version is also reaching coding workflows.
