I echo this issue. I am also experiencing it. And it is different from: #13469
It is as if OpenAI Codex configuration has stopped working entirely

Same for me

No way it is working on other providers. I even tried reverting to older versions of opencode. The issue is from OpenAI side, where they have hardened their API against their usage with other apps like Opencode and Openclaw. So sad to see enshittification everywhere.

not sure its from openAi side
ishan-parihar commentedon Mar 10, 2026
it's definitely not from the opencode side

Same here. I am unable to connect to 5.3 codex as well as any 5.4 models. Seems potentially related to #16927
Edit: Older models like 5.2-Codex and 5.2 seem to work
trogers1 commentedon Mar 11, 2026
It seems the 5.4 models should have been added to the codex allow list: #16274
But, after upgrading to
1.2.24, I can SEE the 5.4 models as select-able options, but not use them.av commentedon Mar 22, 2026
For me GPT-5.4 simply disappeared from OpenAI models list, disconnecting provider and connecting again doesn't restore it. I'm running
opencode serve, restarating the service doesn't bring it back either.trogers1 commentedon Mar 23, 2026
I don't know what changed (not my version, still
1.2.24), but I re-signed-in to my ChatGPT Pro account with SSO and gpt 5.4 seems to be working again... I was using an API key for a while, which worked, but now the normal SSO/OAuth flow seems to work for 5.4 and 5.3 Codex...rekram1-node commentedon Apr 7, 2026
