Sixteen launch partners are named, including OpenCode, Devin, Amp, Warp, Notion and Vercel, with Lovable coming soon. This expands on the Sign in with ChatGPT feature launched in beta in July, which previously covered only identity/account linking. Users can set weekly caps per app in ChatGPT settings, and usage stops once the cap is hit rather than switching to the partner's own billing. The move follows earlier informal implementations by tools like Dactyl and OpenClaw that already let users authenticate via their Codex/ChatGPT accounts to avoid separate token costs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Can I use my ChatGPT Plus or Pro subscription instead of paying separately for OpenAI API usage in third-party coding tools? Yes, OpenAI's Sign in with ChatGPT now lets ChatGPT Plus and Pro subscribers draw on their existing plan allowance inside participating third-party tools instead of paying through the API or the tool's own credits. Sixteen launch partners support this, including OpenCode, Devin, Amp, Warp, Conductor, Notion, and Vercel, with Lovable coming soon. Users set weekly usage caps per app in ChatGPT settings, and included usage simply stops once a cap is reached. _Developers weighing which AI coding tools to adopt can follow rollouts like this one on daily.dev._ ### What is the difference between Sign in with ChatGPT and Codex account login in tools like OpenClaw? Codex account login and Sign in with ChatGPT are listed as separate authentication methods alongside a traditional OpenAI API key. Codex account login was the earlier route some tools used to let users draw on their existing Codex entitlement for model usage. Sign in with ChatGPT is the newer, officially supported method that uses a user's Codex allowance with its own dedicated usage tracking and token limits, managed through ChatGPT settings. _Anyone configuring auth for an AI coding agent can track these distinctions as they evolve on daily.dev._ ## Similar posts on daily.dev - [OpenAI opens ChatGPT subscriptions to OpenClaw's 3.2M users as Anthropic blocks Claude access to the AI agent platform](https://daily.dev/posts/openai-opens-chatgpt-subscriptions-to-openclaw-s-3-2m-users-as-anthropic-blocks-claude-access-to-the-upnsxm5ie) · The Next Web · 66 upvotes · 2 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#openai](https://daily.dev/tags/openai), [#authentication](https://daily.dev/tags/authentication), [#chatgpt](https://daily.dev/tags/chatgpt), [#devin](https://daily.dev/tags/devin) [View this post on daily.dev](https://daily.dev/posts/openai-makes-sign-in-with-chatgpt-a-way-to-use-your-subscription-in-third-party-developer-tools-7ewaoo6ze) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenAI makes ‘Sign in with ChatGPT’ a way to use your subscription in third-party developer tools","url":"https://daily.dev/posts/openai-makes-sign-in-with-chatgpt-a-way-to-use-your-subscription-in-third-party-developer-tools-7ewaoo6ze","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openai-makes-sign-in-with-chatgpt-a-way-to-use-your-subscription-in-third-party-developer-tools-7ewaoo6ze"},"datePublished":"2026-09-29T17:33:43.108Z","dateModified":"2026-09-29T22:27:10.670Z","description":"OpenAI announced at DevDay that ChatGPT Plus and Pro subscribers can now use their existing plan allowance inside third-party developer tools rather than...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b5a905e97da23076b4999a2c7aeb5f23?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b5a905e97da23076b4999a2c7aeb5f23?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The New Stack","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The New Stack","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/newstack","url":"https://daily.dev/sources/newstack"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/openai-makes-sign-in-with-chatgpt-a-way-to-use-your-subscription-in-third-party-developer-tools-7ewaoo6ze","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,openai,authentication,chatgpt,devin","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The New Stack","item":"https://daily.dev/sources/newstack"},{"@type":"ListItem","position":3,"name":"OpenAI makes ‘Sign in with ChatGPT’ a way to use your subscription in third-party developer tools"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/openai-makes-sign-in-with-chatgpt-a-way-to-use-your-subscription-in-third-party-developer-tools-7ewaoo6ze#faq","mainEntity":[{"@type":"Question","name":"Can I use my ChatGPT Plus or Pro subscription instead of paying separately for OpenAI API usage in third-party coding tools?","acceptedAnswer":{"@type":"Answer","text":"Yes, OpenAI's Sign in with ChatGPT now lets ChatGPT Plus and Pro subscribers draw on their existing plan allowance inside participating third-party tools instead of paying through the API or the tool's own credits.
