GPT-6.1 Terra now generally available in GitHub Copilot
GitHub announced that GPT-6.1 Terra, an OpenAI model, is now generally available in GitHub Copilot. According to the announcement, it is designed for everyday agentic coding and terminal work at a lower cost than GPT-6.1 Sol.
Why it matters
Builders using Copilot gain access to a model positioned for routine agentic coding and terminal tasks at a lower cost tier than GPT-6.1 Sol, which may affect model selection and cost planning for coding workflows.
Who should care
Software developers, engineering teams and agencies using GitHub Copilot, and teams building AI coding agents.
What you can do
Check the GitHub Copilot model selector to try GPT-6.1 Terra on a routine coding or terminal task and compare its output and cost against your current model.
