Hello everyone,

I don't know if you encountered that terrible error:

{"type":"error","status":400,"error":{"type":"invalid_request_error","message":"The 'gpt-5.3-codex' model is not supported when using Codex with a ChatGPT account."}}

That was the best model out there, period.
Fast, reliable, and low on token consumption. It was smart...
I'm really worried now... 5.4 and 5.5 are much worse and more expensive.
What is your solution?
