@Ixel111@chrisgpt Thursday next week, perhaps... the spree of vagueposts were pointing mostly at the Codex "superapp" update, and to a lesser extent at the image model (which has also been getting A/B tests)... not so much at the main model :/
@Snixtp β {"type":"error","status":400,"error":{"type":"invalid_request_error","message":"The 'gpt-5.4' model is not supported when using Codex with a ChatGPT account."}}
@ah20im The code it writes (with gpt-5.3-codex-xhigh) usually ends up getting flagged with multiple issues by the Codex PR review agent in GitHub, which presumably uses the same model, so it seems like it should have been able to identify these same issues when it first wrote the code.
