OpenAI expands ‘Sign in with ChatGPT’ to bring Plus and Pro plan usage to third-party tools
The New Stack reports that eligible usage in participating apps counts against subscribers’ existing ChatGPT limits. OpenAI named 16 launch partners, including Devin, Amp, OpenClaw and Vercel; Lovable was listed as coming soon.
TLDR
The New Stack reports that OpenAI expanded ‘Sign in with ChatGPT’ beyond account login, letting Plus and Pro subscribers use their existing plan allowance in participating third-party tools. OpenAI says users can set weekly caps for individual apps. When a limit is reached, included usage stops rather than automatically switching to the third party’s billing.
