When I tried to access gpt-5.5, I received the following error:
{ “error”: { “message”: “The model `gpt-5.5` does not exist or you do not have access to it.”, “type”: “invalid_request_error”, “param”: null, “code”: “model_not_found” } }
Is it that Codex no longer offers GPT-5.5 for free accounts, or has GPT-5.5 been discontinued?
