What changed
OpenAI positions Terra as a faster, lower-cost step up from GPT-5.6 Terra. It describes improvements in understanding images, operating software, and producing clear text. These are vendor claims; we have not independently tested the model.
Who it's for
Developers building workflows around screenshots, documents or computer interfaces may find the visual and tool-use focus useful. Test its output and permissions in your own environment before allowing an agent to act.
How to try it
In the OpenAI API select gpt-6.1-terra. OpenAI also lists it in ChatGPT Work and Codex for eligible plans. Access depends on the product and plan; it is not the same as selecting a model in Chat.
What it costs
OpenAI API: $1 input / $5 output per 1M text tokens. Standard text rate for prompts up to 272K input tokens; higher long-context and regional rates may apply.
Cached input, long-context tiers and other services can be billed differently; an API bill is separate from a ChatGPT subscription.
