GitHub Copilot Retires 3 Models Nov 16: Your Migration Checklist

Описание и применение

GitHub Copilot удалит три модели 16 ноября 2026 года. Команда должна проверить все места, где указаны эти модели, включить новые модели в политику организации и провести оценку поведения.

Задача

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.

Результат

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

Рабочий процесс

• 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

Доказательства

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.

Источник

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.

Источник

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.
