So I’m using Codex on X-Code and all of a sudden it’s giving me an error. The error states: “Codex encountered an error: The ‘gpt-5.3-codex’ model is not supported when using Codex with a ChatGPT account” So then I switch it to 5.5 and 5.2 and it’ll still give me that same error despite me switching. I just don’t understand why. Any help/advice would be appreciated. submitted by /u/Ahutchi3 [link] [comments]
