A dev.to post says Sign in with ChatGPT charges an app's AI requests to the user's own token budget, but only for users who link an account. Users who skip the link or run out of quota fall back to a cheaper model that the developer still pays for.
Reality
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.
Reality
OpenAI now lets ChatGPT Plus and Pro subscribers spend their plan allowance inside tools from 16 launch partners, including Amp and Devin, via Sign in with ChatGPT. The model cost moves to the subscriber's plan, while tools like Dactyl keep billing credits for builds and assets.

OpenAI's new Sign in with ChatGPT lets people carry their identity and existing AI allowance into third-party apps, starting with 16 launch partners. For product teams, new users arrive signed in with AI budget to spend, and OpenAI holds both.

OpenAI says ChatGPT will suggest third-party apps mid-conversation to its 1.2 billion weekly users, who can connect and use them without leaving the chat. Teams that rely on app stores for discovery now face a second storefront where the assistant makes the pick.
