Upgraded to ChatGPT Plus but still using version 3.5

Has any experienced this problem? I asked ChatGPT which version it’s using and the response was: “I am ChatGPT, based on the GPT-3.5 architecture.”. But I am a Plus member.

Also, trying to use the API and I don’t have gpt-4. I confirmed using /v1/models of the API.


GPT is not reliable at responding accurately about what model it is using. It isn’t trained on itself. Trust the UI model selector.

ChatGPT and API are completely separate products. Paying for ChatGPT Plus won’t get you API access or GPT-4 access. You’ll need to signup for API and enter your billing info at platform.openai.com to use the API, then wait for GPT-4 access (rolling out to all developers at end of month).
