Adds GPT-5.4 to the OpenAI Codex (ChatGPT Plus/Pro) provider model catalog so users with a ChatGPT Plus/Pro subscription can select it from the model dropdown.
What changed
Added a
gpt-5.4entry toopenAiCodexModelsinpackages/types/src/providers/openai-codex.ts, matching the capabilities from the OpenAI API catalog but with subscription-based pricing (zero cost).Why
Customer reported that GPT-5.4 is available when using the OpenAI API provider but missing from the ChatGPT Plus/Pro (OAuth) provider. Since Plus/Pro subscribers have access to GPT-5.4 via chatgpt.com, our Codex model catalog should include it.
Risk
If the Codex backend (
chatgpt.com/backend-api/codex) does not support thegpt-5.4model ID, users will get an error. Should be verified with a quick manual test before merging.Interactively review PR in Roo Code Cloud
