buildOne report1 publisher Sign in with ChatGPT lets Plus and Pro users cover an app's AI requests from their own plan
OpenAI's Sign in with ChatGPT lets Plus and Pro users run an app's AI requests on their own plan, up to a weekly cap they set per app. That cap reserves none of the user's quota, so builders still need their own API key for any request the plan cannot cover.
