## OpenAI Codex

`openai-codex` is separate from standard `openai`: distinct provider ID, runtime kind, credential store,
routes and request adapter. Current recommended catalog includes `gpt-5.5`, `gpt-5.6-sol`,
`gpt-5.6-terra`, `gpt-5.6-luna`, `gpt-5.4`, `gpt-5.4-mini`, `gpt-5.3-codex-spark` and `gpt-image-2`

`gpt-image-2.5-sunburst`, `gpt-image-2.5-flare` and `gpt-image-2`. Chat models require provider-db
metadata. Curated image models remain listed when metadata is missing and use the OpenAI image-route
compatibility fallback; explicit user model settings retain precedence. Connection check uses
`gpt-5.6-luna`. GPT-5.4, GPT-5.4 mini and Codex Spark are omitted following their
[Codex retirement](https://learn.chatgpt.com/docs/models#deprecated-codex-models).

Codex requests include required instructions and backend routing headers, preserve streaming/tool/reasoning
behavior, and surface entitlement failure without logging token or account identifiers. Image generation
behavior, and surface entitlement failure without logging token or account identifiers. Rejected refresh
tokens retain their HTTP failure metadata and require sign-in again; media CLI calls return
`authentication_failed` with `retriable: false`. Other media provider failures expose only normalized
HTTP status and retryability. Unreadable credential files remain storage failures. OAuth error bodies
are parsed before diagnostic messages are limited to 1,000 characters. Image generation
uses the same OAuth credential path with `/images/generations`; Responses-only body normalization does not
apply to image requests. The image-generation projection preserves shared OpenAI image settings but disables
vision input because the standalone route accepts only text prompts. Background provider-db refresh skips
