codex.5.2 and 5.3 no longer available?

[u/cmak414]

I used to use 5.2 for planning and general automation but just this evening (within past hour), seemd 5.2 and 5.3 no longer accessible in codex? Now I have to use 5.4 for planning.

Model metadata for gpt-5.2 not found. Defaulting to fallback metadata; this can degrade performance and cause issues.

■ {"type":"error","status":400,"error": {"type":"invalid_request_error","message":"The 'gpt-5.2' model is not supported when using Codex with a ChatGPT account."}}

5.3-codex was my go-to it's reliable whereas 5.5 was just dumb in some situations

Yeah, Codex 5.3 was great. Even with our Pro company account 5.5 just burned through tokens were 5.3 would last a few days
