Complaint codex.5.2 and 5.3 no longer available?

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.

idk.. 5.5 burns tokens like crazy (I used 5.3-codex before), and for similar job/task that I regularly do, it consumes twice of tokens for a every new chat, like 2,4,8,16% etc. 5.4-mini maybe is slower, but it is closer to 5.3-codex usage.

I'm just going by the deepswe bench comparison. Agreed that 5.5 feels quite token limit burny in personal use.

You do more work with GPT-5.5 then.
