OpenAI has announced that it’s making it easier for ChatGPT subscribers to use their allowance inside third-party AI and coding platforms such as Amp, Devin, Lovable, and OpenClaw, alongside broader developer and productivity platforms including Notion and Vercel. The announcement came on Tuesday at OpenAI DevDay, the fourth incarnation of its annual developer conference, where the AI juggernaut unveiled a number of notable tidbits, including Dots, a new class of always-on agents, and GPT-6.1 Sol, its latest model for coding, computer use and professional work. Sign in with ChatGPT: Identity and plan usage Back in July OpenAI had quietly released Sign in with ChatGPT as a beta feature in partnership with companies including Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel. At that point, the feature was chiefly about identity. Users could create or access an account on participating sites using their ChatGPT login, while supported plugins could use the same sign-in process to create or link an account with the underlying service. OpenAI said partners received a user’s name, email address and profile picture, while any additional plugin permissions had to be approved separately. “Continue with ChatGPT” in Supabase Now, OpenAI is extending that idea beyond identity, allowing ChatGPT Plus and Pro subscribers to use their existing plan allowance inside participating third-party tools. “Eligible” OpenAI usage in those services counts against the user’s existing ChatGPT plan limits, with controls for how much each partner can consume. OpenAI has named 16 launch partners for ChatGPT plan usage, spanning both open-source and commercial tools. The currently available services include OpenCode, OpenClaw, Pi, T3, Hyperagent, Hermes Agent, Vorflux, Amp, Dactyl, Kilo Code, Warp, Conductor, Devin, Notion and Vercel, with Lovable “coming soon.” Sign in with ChatGPT (OpenAI) An OpenAI spokesperson tells The New Stack that more will be added to the mix in the future. “We’re starting with these 16 launch partners today, and we’ll expand quickly,” the company says in a statement. Extending ChatGPT subscriptions It’s worth noting that at least one of the launch partners has been showcasing this integration for the best part of a month already. Ryan Dahl, a software engineer known for Node.js, took to X in late August to debut Dactyl, a vibe-coding platform for building native mobile apps. As part of the launch, Dahl highlighted the option to bring an existing ChatGPT subscription into Dactyl. Introducing Dactyl Dactyl is a vibe coding platform for native iOS and native Android apps. What's interesting about it is the device simulator: we've built a SwiftUI renderer in WASM. This means as you're developing, you get low latency in browser canvas simulation of the app… — Ryan Dahl (@rough__sea) August 24, 2026 Dactyl offers a free plan with 100 credits a month for trying the service, while its $20-a-month Builder plan puts the ChatGPT connection front and center, promising that the “Agent runs on your ChatGPT subscription — no token bills from us.” Dactyl’s documentation provides a little more detail, too. Connecting ChatGPT covers the agent that interprets a user’s request and writes the Swift code. Compiling the app, generating icons and images, creating 3D assets and publishing continue to consume Dactyl credits. Users don’t need to supply an OpenAI API key: authentication happens through their normal ChatGPT account. At the time, Dactyl said plan sharing was limited to personal ChatGPT Pro subscribers on its Builder plan or higher. Plus and Business users could still sign in with ChatGPT, but that only provided the account connection; their Dactyl builds continued to consume Dactyl credits rather than drawing on their ChatGPT allowance. The official announcement from OpenAI today broadens plan usage to both Plus and Pro subscribers. OpenAI says third-party requests draw from the ChatGPT Work and Codex usage already included in a subscriber’s plan. Users can set weekly caps for individual apps, and once the relevant limit is reached, included usage stops rather than automatically switching to the third party’s own billing. Dactyl, for what it’s worth, wasn’t the first third-party tool to let users draw on an existing ChatGPT subscription for OpenAI-powered usage. In practice, that meant a service could use a user’s existing ChatGPT/Codex entitlement for model usage, rather than requiring them to pay separately through the OpenAI API or the service’s own credits. OpenClaw was one example of this in operation. In May, it announced that users could power OpenAI agent turns with their existing ChatGPT subscription through OpenAI’s Codex authentication route. Users signed into their ChatGPT/Codex account from the OpenClaw command line, creating what OpenClaw called a “subscription-backed Codex auth profile.” And so today’s launch brings those various implementations into a wider program that users can manage directly through ChatGPT. “Today’s rollout builds on that earlier work, bringing plan usage to more participating tools with clearer visibility and controls in ChatGPT settings,” the OpenAI spokesperson says. Portable ChatGPT subscriptions The distinction between that earlier approach and today’s announcement is also now included in OpenClaw’s own documentation. It lists Codex account login and the new Sign in with ChatGPT option as separate authentication methods, alongside a traditional OpenAI API key. Sign in with ChatGPT is specifically described as using a user’s Codex allowance with its own usage tracking and token limits. And this also helps illustrate what OpenAI is adding today. A ChatGPT subscription and OpenAI’s developer API have traditionally been separate products: developers using OpenAI through its API generally supply an API key and pay according to usage, while third-party services may instead pass those model costs on through their own subscriptions or credit systems. Sign in with ChatGPT gives participating services an official route for letting users bring their existing ChatGPT allowance with them. For someone already paying for ChatGPT, that can mean avoiding a separate OpenAI API bill or spending additional partner credits on the OpenAI-powered portion of a service. Third-party companies can still charge for the other parts of their product, as Dactyl does for things like compiling, image generation and publishing.
