[Bug]: gpt-daybreak-blue-latest missing from OpenCodex and Codex App model lists #1480

Description

@liewcf

Client or integration

Codex App

Provider or upstream service

openai

OpenCodex version

2.10.0

Endpoint or capability

model discovery / model catalog

Current behaviour

When Codex App is routed through OpenCodex 2.10.0 on macOS, gpt-daybreak-blue-latest is absent from both the OpenCodex model list and the Codex App model picker. There is no response body or error because the model is omitted from discovery.

Expected behaviour

OpenCodex should discover and expose gpt-daybreak-blue-latest for an eligible OpenAI account, so it appears in OpenCodex's catalog and in the connected Codex App model picker. The same account shows the model when Codex connects directly without OpenCodex.

Minimal redacted request or reproduction

1. On macOS, configure Codex App to route through OpenCodex 2.10.0 using the OpenAI provider.
2. Open the OpenCodex model list and search for `gpt-daybreak-blue-latest`.
3. Open the Codex App model picker and search for the same model.
4. Disconnect or bypass OpenCodex and connect Codex directly with the same OpenAI account.
5. Open the Codex App model picker again.

Result: the model is missing in steps 2 and 3, but appears in step 5.

Actual response or error

No HTTP error was displayed. `gpt-daybreak-blue-latest` was simply absent from both model lists while routed through OpenCodex.

Upstream documentation

No public model-specific specification is available. Expected behavior is based on the concrete Codex App client behavior: the same eligible OpenAI account exposes gpt-daybreak-blue-latest when connected directly, but not when routed through OpenCodex.

Suggested mapping or implementation notes

Ensure OpenAI model discovery/catalog synchronization preserves newly available model slugs such as gpt-daybreak-blue-latest and propagates them to the Codex App catalog instead of filtering them out.

Additional context and attachments

  • Reproduced on macOS on August 11, 2026.
  • OpenCodex version: 2.10.0.
  • Client: Codex App.
  • Provider: OpenAI.
  • Direct routing of the slug through OpenCodex was not tested.
  • OpenCodex was uninstalled after reproducing, so additional proxy logs are not available.

Checks

  • I searched existing provider and compatibility issues.
  • The request and response were redacted.
  • The expected behaviour is based on an upstream specification or a concrete client requirement.
