so I am using the chatgpt app with codex and I am on the 20x pro plan and when I am trying to prompt it it gives me this “The ‘gpt-5.6-sol’ model is not supported when using Codex with a ChatGPT account.” I have been able to used it before so why is this happening?
Hi @cyruszei,
I wasn’t able to reproduce this issue during testing with my personal ChatGPT 20x Pro plan. Could you please share the steps needed to reproduce the error, along with any relevant screenshots or configuration details? It’ll help the team investigate better.
Thank you.
Thanks for flagging this, @cyruszei, and thanks @sps for checking and asking for the reproduction details.
Once we have the exact steps, screenshots, and any relevant Codex configuration, we can proceed with the investigation.

that because it happens when the subscription expired:) Just happened to me.
Welcome to the Community @Pafuin and @minya_zhua. Thanks for reporting this, @minya_zhu. That error suggests the selected model isn’t currently supported with Codex on a ChatGPT account.
Please create a support ticket by emailing support@openai.com and include the exact error message, your app version, and device details so the team can investigate further.
