GitHub Copilot to Deprecate Claude Opus-5, GPT-5.6 Terra Models Nov 16

By PulseAugur Editorial · [1 sources] ·

GitHub Copilot will remove three AI models—Claude Opus-5, Claude Opus 4.8, and GPT-5.6 Terra—from its model picker on November 16, 2026. While these models will still be accessible through their respective vendors' APIs, their removal from Copilot may affect workflows and integrations that rely on them. GitHub is suggesting alternative models, which generally offer a lower per-token cost, though users are advised to monitor their AI credit consumption. Developers are encouraged to update any hardcoded model names in their scripts and configurations before the deprecation date. AI

IMPACT Developers using GitHub Copilot will need to update their workflows to accommodate model changes and potentially monitor AI credit usage with new pricing.
