OpenAI makes ‘Sign in with ChatGPT’ a way to use your subscription in third-party developer tools

OpenAI is letting ChatGPT Plus and Pro users spend their plan inside third-party apps. That could make tools easier to try, but it also ties more products to OpenAI’s billing.

OpenAI is turning Sign in with ChatGPT into more than a login button. On Tuesday at DevDay, the company said Plus and Pro subscribers will be able to use their existing ChatGPT plan allowance inside participating third-party tools, including AI and coding products like Amp, Devin, Lovable, and OpenClaw, plus services such as Notion and Vercel.
The pitch is simple: if users already pay OpenAI, they may be more willing to try a partner app when the model usage comes from the same subscription. Sam Altman said the idea is to lower the barrier to adoption for those tools because people do not have to cover their token costs up front. OpenAI also said partner usage will count against the user’s ChatGPT limits, with controls over how much each service can consume.
This is a step beyond the beta OpenAI released in July, when Sign in with ChatGPT was mostly about identity. At that stage, users could log into participating sites with their ChatGPT account, and supported plugins could use that sign-in flow to create or link an account with the underlying service. Partners received basic profile details, while extra permissions still needed separate approval.
Now the company is folding plan usage into the same system. OpenAI named 16 launch partners: OpenCode, OpenClaw, Pi, T3, Hyperagent, Hermes Agent, Vorflux, Amp, Dactyl, Kilo Code, Warp, Conductor, Devin, Notion and Vercel, with Lovable listed as coming soon. OpenAI says more partners are on the way and that it will expand the program quickly.
Some of this has already been visible in the wild. Dactyl, a vibe-coding platform for native iOS and Android apps, had shown a ChatGPT subscription connection in August, with its Builder plan promising that the agent runs on the user’s ChatGPT subscription. OpenClaw has also documented a subscription-backed Codex auth profile. What OpenAI is doing now is taking those separate implementations and giving them a more official path, with usage tracking and caps managed from ChatGPT settings.
My take — AI-written commentary, not fact-checked reporting
This is OpenAI doing what every platform wants to do: turn a subscription into a passport. Handy for users, sure, but it also makes third-party tools feel a lot less independent. The industry keeps calling that convenience; finance people usually call it distribution power.
