GitHub Copilot Retires 3 Models Nov 16: Your Migration Checklist

说明与用途

GitHub Copilot 将在2026年11月16日停用三种模型。团队需要审计所有引用，启用新模型并在截止日期前评估行为。

问题

GitHub Copilot will remove three model names (Claude Opus 4.8, Claude Opus 5, GPT-5.6 Terra) from all Copilot experiences on November 16, 2026, requiring teams to update workflows and integrations.

结果

Teams that complete the checklist will avoid failures after November 16 and maintain consistent model behavior across all Copilot experiences.

工作流

• Audit all repos, scripts, CI, and docs for the three retired model names using git grep patterns
• Verify organization model policies enable the suggested replacements
• Enable replacements if the org disabled the default model
• Run side‑by‑side evaluations of key prompts on old and new models
• Choose between GPT‑6.1 Sol and GPT‑6 Luna based on quality and cost
• Update runbooks, onboarding docs, and team communications to reference new models

证据

GitHub published a changelog entry on October 15 with a date and three model names: on November 16, 2026, Claude Opus 4.8, Claude Opus 5, and GPT-5.6 Terra disappear from every GitHub Copilot experience.

Audit anything that names these models by ID this week - prompts, scripts, agents, CI jobs, IDE settings - and confirm the replacements are enabled in your org's model policies.

The second pattern matches opus-5 and Opus 5 while skipping opus-5-5 and Opus 5.5. Adjust for how your tooling spells model IDs - display names and machine identifiers often differ.
