Official source conflict
Official sources disagree
Unknown — conflicting GPT-5.4 availability in Codex for ChatGPT-signed-in users
Source A:Codex pricing — The Codex pricing table still displays legacy GPT-5.4 and GPT-5.4 mini rows.
Source B:Using Codex with your ChatGPT plan — The Help Center states those models are no longer available in Codex for users signed in with ChatGPT from August 31, 2026.
Applies to: ChatGPT-signed-in Codex users after 2026-08-31
Decision impact: Do not treat GPT-5.4 as a current Codex ChatGPT-login model. API-provider rows remain a separate access path.
TraceCheck status: Unresolved — Derived outputs must not treat one side as settled Fact.
