Pull request overview
This PR adds a client-side fallback mechanism for the gpt-5.3-codex model in the GitHub Copilot plugin, ensuring the model is available even before the upstream models.dev catalog includes it. The implementation creates a fallback model by copying properties from existing Codex models (prioritizing gpt-5.2-codex, then 5.1-codex-max, 5.1-codex, and 5.1-codex-mini) and overriding key fields.
Changes:
- Added
ensureGpt53Codexfunction to inject gpt-5.3-codex model when missing from provider catalog - Integrated the fallback into the Copilot auth loader to ensure model availability
- Aligned release date with official model announcement (2026-02-05)
