GPT-6.1 Terra Pro · OpenRouter
OpenRouter serves the Terra model with extra reasoning in pro mode. It can use substantially more tokens; this is a hosting option, not a separately verified base model.
Catalog added 2026-10-26 UTC · Checked 2026-11-03. Catalog addition and provider launch are separate dates.
We still need comparable independent tests. You can compare the confirmed features and limits below, but we cannot yet give this version an Agent Fit or Practical Value rating. Test it on your own tasks before switching; results for another version or thinking setting may not apply.
What you can use today
Token prices measure the small pieces of text the model reads or produces. Capacity is the amount the service accepts in a request; check the limits below for any fallback to another model. A dash means the rate is unverified.
Exact catalog ID: openai/gpt-6.1-terra-pro. The catalog describes pro reasoning mode on the same Terra model. Do not treat its higher token use as a verified quality improvement.
No separate native OpenAI Terra Pro model page was found. This page describes the exact OpenRouter offer; scores from Terra or other GPT models are not assigned to it.
Rates describe the catalog offer observed on 2026-11-03. Allow for retries and any tool fees. Models that think before answering may also charge for that work.

Test it before switching
Give each model the same examples, tools and definition of success. Record correct outcomes, response time, retries and total cost. A cheaper token price does not guarantee a cheaper completed task.
