GitHub has deprecated multiple models from Anthropic and OpenAI across its Copilot suite, effective February 17, 2026.
The deprecation impacts all GitHub Copilot experiences, including Copilot Chat, inline edits, ask mode, agent mode, and code completions. However, GitHub's announcement does not specify which specific models were deprecated or provide a transition timeline for users currently relying on affected versions.
What we know
The deprecation was announced on February 19, 2026, two days after the effective date. The move affects both Anthropic and OpenAI model integrations with GitHub's code completion and AI assistance platform.
GitHub did not provide additional details regarding:
- Names of deprecated models
- Replacement models users should migrate to
- Grace period or sunset dates for deprecated models
- Migration guidance for existing integrations
What this means
GitHub users relying on specific Anthropic or OpenAI models through Copilot need to check GitHub's full changelog for model-specific details. The deprecation suggests either model performance improvements elsewhere in the lineup, licensing changes, or technical reasons for phasing out older versions. Developers should review their Copilot configurations to identify which models they currently use and prepare for potential switching costs or API adjustments.
