gpt-5.3-codex is only accessible via the ChatGPT Codex endpoint (chatgpt.com/backend-api/codex/responses) which requires OAuth authentication. It is not available on the OpenAI API platform.

When a user authenticates with a standard OpenAI API key via 'opencode auth login', this model appears available but fails with a 404 error at runtime. Remove OAuth-only models from the provider model list for API key users.

Note: gpt-5.2-codex and other codex models that ARE available on the OpenAI API platform are intentionally kept.
