OpenAI Revolutionizes ChatGPT with Third-Party App Integration

OpenAI launches apps inside of ChatGPT | TechCrunch

OpenAI is launching a new way for developers to build applications inside of ChatGPT. Starting Monday, users in ChatGPT will be able to access interactive applications from companies like Spotify, Figma, Coursera, Zillow, and Canva. OpenAI is also launching a preview of the Apps SDK on Monday, the developer-facing toolkit to build these apps. OpenAI made the announcement at its annual developer conference, DevDay 2025. "We want ChatGPT to be a great way for people to make progress, to be more productive, more inventive, to learn faster, to do whatever they're trying to do in their lives better," said CEO Sam Altman. "[Apps inside of ChatGPT] will enable a new generation of apps that are interactive, adaptive, and personalized, that you can chat with." The new system is OpenAI's latest attempt to build an ecosystem of apps around its flagship AI product, ChatGPT. The launch follows OpenAI's previous attempts to let developers build interactive applications, such as through its GPT Store. Unlike that product, which asked ChatGPT users to access a separate app store, Monday's launch puts apps directly in ChatGPT's responses, and lets users call up different applications in their everyday conversations. This gives developers better distribution for the apps they build, and aims to make a richer experience for users in ChatGPT. By calling out the names of different apps, users can draw in content from a variety of services. For example, ChatGPT users can say "Figma, turn this sketch into a workable diagram" to call up the Figma app. Users can also call up the Coursera app by asking, "Coursera, can you teach me something about machine learning." In a demo of Zillow's application, users could access for apartments in their area within a specific price range. ChatGPT then pulled up an interactive map showing options, and users could talk with ChatGPT to learn more about each one. ChatGPT will also surface relevant apps when they could be helpful to a user. If someone asks for a playlist for a party this weekend, ChatGPT may call up the Spotify app in the conversation. OpenAI says the new system is built using the Model Context Protocol (MCP), which allows developers to connect their data sources to an AI systems. ChatGPT apps can also trigger actions, and render a fully interactive UI in the chatbot's responses. Certain apps are able to display videos in ChatGPT, which will be pinned to the top of the web-page and can be altered based on user requests. If users are already subscribed to a product, they'll be able to login to their account directly in ChatGPT to access certain features. Altman also says OpenAI will support ways to monetize apps inside of ChatGPT in the future, including through the company's recently launched Instant Checkout feature in ChatGPT.

You Can Now Add Spotify, Zillow to ChatGPT, But Don't Call It an App Store

When he's not battling bugs and robots in Helldivers 2, Michael is reporting on AI, satellites, cybersecurity, PCs, and tech policy. Don't miss out on our latest stories. Add PCMag as a preferred source on Google. ChatGPT can now run third-party apps, including Spotify, for an experience that OpenAI says is closer to an operating system than an app store. At its DevDay conference today, OpenAI said the app support goes beyond offering plugins for the chatbot. A key difference is that a user can access the apps within the ChatGPT prompt. This includes displaying "interactive interfaces you can use right in the chat," the company says. "The magic of this new generation of apps in ChatGPT is how they blend familiar interactive elements-like maps, playlists, and presentations-with new ways of interacting through conversation," OpenAI wrote in a blog post. For example, a user can query ChatGPT to access Spotify to list and play popular tracks from the streaming app. In a demo at the developer conference, the company also showed that a user could access Zillow directly within ChatGPT to search and display property listings. In addition, ChatGPT can also suggest a user try out an app. The company is rolling out the feature starting today for all logged-in ChatGPT users outside of the European Union, including on free accounts.The first supported apps include Booking.com, Canva, Coursera, Figma, Expedia, Spotify, and Zillow. "What you're going to see over the next six months is an evolution of ChatGPT from an app that is really, really useful to something that'll be a bit more like an operating system, where you can access different services, you can access software," OpenAI's head of ChatGPT, Nick Turley, said during a Q&A with the press. This will include both existing software and new software "built natively on top of ChatGPT," which promises to offer a different experience. Also today, OpenAI revealed that ChatGPT has now grown to over 800 million weekly active users. "I imagine you're starting your day with ChatGPT," Turley said. He suggested the chatbot has become an entry point for the web for some users. The news also raises a question about how ChatGPT will recommend the apps users should run. For now, OpenAI CEO Sam Altman told the press the company doesn't want to break user trust by recommending unworthy apps. "We're hyper aware of the need to be careful," he said. In the meantime, the company is trying to get companies on board by offering a new apps software development kit, which is arriving in preview mode. Users can expect other apps to launch in the coming weeks, including Target, DoorDash, Instacart, Uber, and Uber Eats. "For Uber Eats, ChatGPT will detect when a user wants to place an Uber Eats order, confirm details like delivery address, and then display nearby restaurant and menu options directly in ChatGPT," Uber said. "To complete their order, users will then be prompted to launch the Uber Eats app directly from ChatGPT." Disclosure: Ziff Davis, PCMag's parent company, filed a lawsuit against OpenAI in April 2025, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.

OpenAI opens ChatGPT to referring queries to developer apps

Integrate your apps via their Apps SDK and maybe they'll send you some business OpenAI on Monday pitched its coding tools to software developers in the hope of generating the usage and revenue necessary to recoup the vast sums it spends to create and run its AI services. CEO Sam Altman presided over OpenAI DevDay 2025 at San Francisco's Fort Mason Center, the third such event since the company began chewing through massive amounts of costly cloud computing to resell scraped data as service. "Today, 4 million developers have built with OpenAI," said Altman in a streamed presentation. "More than 800 million people use ChatGPT every week, and we process over six billion tokens per minute on the API, thanks to all of you. AI has gone from something people play with to something people build with every day." That hasn't been enough to turn a profit. According to The Information, OpenAI generated $4.3 billion in revenue in the first half of 2025, 16 percent more than all of 2024, and reported a net loss of $13.5 billion, up from $3.1 billion during the same period a year ago. OpenAI did not respond to a request to confirm those figures. But Altman insists that there's never been a better time to build software applications with OpenAI, and he provided some details on how the AI giant aims to help developers do that. Altman and underlings went on to describe: Here's a rundown of the most important and interesting bits. Apps SDK provides a way to discover and invoke apps through the ChatGPT interface. "When someone's using ChatGPT, you'll be able to find an app by asking for it by name," Altman explained. "For example, you could sketch out a product flow for ChatGPT and then say 'Figma, turn the sketch into a workable diagram.' The Figma app will take over, respond, and complete the action." (In a sign of how desperate investors are to get in on the AI boom, Figma's stock went up 16 percent after Altman talked about them in his presentation.) Functionally, the idea is similar to an Android Intent - a way to pass data from one mobile app to another. But OpenAI aims to generalize this sort of cross-app communication so it works on a broader level, through natural language. And it is doing so in a way that will have economic implications for app developers. To participate, developers have to set up metadata that informs ChatGPT about their app's functions, create an MCP server to handle communication with ChatGPT, and connect the MCP server to ChatGPT. They have a substantial incentive to do so given the size of the ChatGPT audience - integration is a prerequisite for having ChatGPT surface apps. However, app makers who agree to entrust distribution to a third party may find themselves at the mercy of that entity, as Apple's App Store and Google Play have demonstrated. Developers comfortable with that tradeoff will be able to register their apps so that ChatGPT can route queries to those apps when the topic and metadata suggest a match. Alexi Christakis, a member of OpenAI's technical staff, explained how ChatGPT app discovery works when the user hasn't tried the app before; it requires user consent to connect the app to your ChatGPT conversation. AgentKit provides a way to configure workflows to be carried out by agents (models running tools in a loop). The Agent Builder offers visual flowcharting to connect models with data and tools. The Connector Registry provides an administrative panel governing how ChatGPT and the API get linked to other services, such as pre-built connectors for Dropbox, Google Drive, Sharepoint, and Microsoft Teams, and third-party MCP servers. "AgentKit is a complete set of building blocks available in the OpenAI platform designed to help you take agents from prototype to production," said Altman. "It is everything you need to build, deploy, and optimize Agentic workflows with way less friction." Altman described how grocery chain Albertson's built an agent using AgentKit. Faced with a scenario in which ice cream sales had dropped unexpectedly by 32 percent, the grocery chain would typically have undertaken a long process of reporting and spreadsheet data analysis, he said. "Now, an associate can just ask the agent what's going on," Altman said. "The agent will look at the full context of everything it can discover - seasonality, historical trends, external factors - and it will give a recommendation." He didn't address whether the resulting recommendation would reverse the sales slump or how it might compare to slower human data analysis. The utility of AI intervention was also left unaddressed in a demonstration of Agent Builder by OpenAI technical staff member Christina Huang. She created an agent to recommend sessions at OpenAI's DevDay in less than eight minutes. Whether this low-code experience produced something of value depends on whether this is the sort of task one prefers to delegate to a hastily-assembled web page widget or whether it's the sort of challenge one might manage without aid. Altman concluded, "We want OpenAI to be a great platform for this new era of building. We think things are going to get pretty incredible pretty soon."

OpenAI: You can use third-party apps like Spotify and Canva in ChatGPT

OpenAI and CEO Sam Altman want ChatGPT to evolve beyond a conversational tool into a full-fledged digital assistant -- one that can use other apps for you. The company announced a new initiative to create a "new generation of apps in ChatGPT," allowing users to connect and interact directly with third-party services inside the chatbot. The new feature was unveiled during OpenAI's Dev Day, during which the company showcased several live demos highlighting how this could work in practice. In one example, ChatGPT connected to Spotify to generate a playlist based on the user's favorite songs, created and saved automatically within the Spotify app. Another demo showed an OpenAI engineer tagging Canva in the chat to design a poster for a dog-walking business. After specifying that it should look whimsical and bright with a sans-serif font, ChatGPT returned multiple poster options generated through Canva. The system prompts users for permission the first time an app is connected, but once approved, it can use that app freely in future chats. OpenAI also demonstrated educational and real estate integrations, like creating a machine learning lesson plan via Coursera and finding homes for sale in Pittsburgh through Zillow. Starting today, ChatGPT users can connect to apps including Spotify, Canva, Booking.com, Expedia, Coursera, Zillow, and Figma. Altman added that more integrations, such as DoorDash and Uber, are coming later this year. Additionally, developers will soon be able to submit their own apps for review and publication within ChatGPT. OpenAI also plans to launch a dedicated app directory, giving users an easier way to discover and install integrations. As for monetization, Altman says the company will share more details in the near future. This push marks a key step in OpenAI's broader vision of agentic AI, especially after the company recently introduced Instant Checkout, a feature that lets users make purchases directly in chat.

OpenAI announces Apps SDK allowing ChatGPT to launch and run third party apps like Zillow, Canva, Spotify

OpenAI's annual conference for third-party developers, DevDay, kicked off with a bang today as co-founder and CEO Sam Altman announced a new "Apps SDK" that makes it "possible to build apps inside of ChatGPT," including paid apps, which companies can charge users for using OpenAI's recently unveiled Agentic Commerce Protocol (ACP). In other words, instead of launching apps one-by-one on your phone, computer, or on the web -- now you can do all that without ever leaving ChatGPT. This feature allows the user to log-into their accounts on those external apps and bring all their information back into ChatGPT, and use the apps very similarly to how they already do outside of the chatbot, but now with the ability to ask ChatGPT to perform certain actions, analyze content, or go beyond what each app could offer on its own. "This will enable a new generation of apps that are interactive, adaptive and personalized, that you can chat with," Altman said. While the Apps SDK is available today in preview, OpenAI said it would not begin accepting new apps within ChatGPT or allow them to charge users until "later this year." Built atop common MCP standard Built on the open source standard Model Context Protocol (MCP) introduced by rival Anthropic nearly a year ago, the Apps SDK gives third-party developers working independently or on behalf of enterprises large and small to connect selected data, "trigger actions, and render a fully interactive UI [user interface]" Altman explained during his introductory keynote speech. The Apps SDK includes a "talking to apps" feature that allows ChatGPT and the underlying GPT-5 or other "o-series" models piloting it underneath to obtain updated context from the third-party app or service, so the model "always knows about exactly what you're user is interacting with," according to another presenter and OpenAI engineer, Alexi Christakis. Developers can build apps that: * appear inline in chat as lightweight cards or carousels * expand to fullscreen for immersive tasks like maps, menus, or slides * use picture-in-picture for live sessions such as video, games, or quizzes Each mode is designed to preserve ChatGPT's minimal, conversational flow while adding interactivity and brand presence. Early integrations with Coursera, Canva, Zillow and more... Christakis showed off early integrations of external apps built atop the Apps SDK, including ones from e-learning company Coursera, cloud design software company Canva, and real estate listings and agent connections search engine, Zillow. Altman also announced Apps SDK integrations with additional partners not demoed officially during the keynote including: Booking.com, Expedia, Figma and Spotify and in documentation, said more upcoming partners are on deck: AllTrails, Peloton, OpenTable, Target, theFork, and Uber, representing lifestyle, commerce, and productivity categories. The Coursera demo included an example of how the user onboards to the external app, including a new login screen for the app (Coursera) that appears within the ChatGPT chat interface, activated simply by a text prompt from the user asking: "Coursera can you teach me something about machine learning"? Once logged in, the app launched within the chat interface, "in line" and can render anything from the web, including interactive elements like video. Christakis explained and showed the Apps SDK also supports "picture-in-picture" and "fullscreen" views, allowing the user to choose how to interact with it. When playing a Coursera video that appeared, he showed that it automatically pinned the video to the top of the screen so the user could keep watching it even as they continued to have a back-and-forth dialog in text with ChatGPT in the typical input/output prompts and responses below. Users can then ask ChatGPT about content appearing in the video without specifying exactly what was said, as the Agents SDK pipes the information on the backend, server-side, from the connected app to the underlying ChatGPT AI model. So "can you explain more about what they're saying right now" will automatically surface the relevant portion of the video and provide that to the underlying AI model for it to analyze and respond to through text. In another example, Christakis opened an older, existing ChatGPT conversation he'd had about his siblings' dog walking business and resumed the conversation by asking another third-party app, Canva, to generate a poster using one of ChatGPT's recommended business names, "Walk This Wag," along with specific guidance about font choice ("sans serif") and overall coloration and style ("bright and colorful.") Instead of the user manually having to go and add all those specific elements to a Canva template, ChatGPT went and issued the commands and performed the actions on behalf of the user in the background. After a few minutes, ChatGPT responded with several poster designs generated directly within the Canva app, but displayed them all in the user's ChatGPT chat session where they could see, review, enlarge and provide feedback or ask for adjustments on all of them. Christakis then asked for ChatGPT to turn one of the slides into an entire slide deck so the founders of the dog walking business could present it to investors, which did it in the background over several minutes while he presented a final integrated app, Zillow. He started a new chat session and asked a simple question: "based on our conversations, what would be a good city to expand the dog walking business." Using ChatGPT's optional memory feature, it referenced the dog walk conversation and suggested Pittsburgh, which Christakis used as a chance to type in "Zillow" and "show me some homes for sale there," which called up an interactive map from Zillow with homes for sale and prices listed and hover-over animations, all in-line within ChatGPT. Clicking a specific home also opened a fullscreen view with "most of the Zillow experience," entirely without leaving ChatGPT, including the ability to request home tours and contact agents and filtering by bedrooms and other qualities like outdoor space. ChatGPT pulls up the requested filtered Zillow search as well as provides a text-based response in-line explaining what it did and why. The user can then ask follow-up questions about the specific property -- such as "how close is it to a dog park?" -- or compare it to other properties, all within ChatGPT. It can also use apps in conjunction with its Search function, searching the web to compare the app information (in this case, Zillow) with other sources. Safety, privacy, and developer standards OpenAI emphasized that apps must comply with strict privacy, safety, and content standards to be listed in the ChatGPT directory. Apps must: * serve a clear and valuable purpose * be predictable and reliable in behavior * be safe for general audiences, including teens aged 13-17 * respect user privacy and limit data collection to only what's necessary Every app must also include a clear, published privacy policy, obtain user consent before connecting, and identify any actions that modify external data (e.g., posting, sending, uploading). Apps violating OpenAI's usage policies, crashing frequently, or misrepresenting their capabilities may be removed at any time. Developers must submit from verified accounts, provide customer support contacts, and maintain their apps for stability and compliance. OpenAI also published developer design guidelines, outlining how apps should look, sound, and behave. They must follow ChatGPT's visual system -- including consistent color palettes, typography, spacing, and iconography -- and maintain accessibility standards such as alt text and readable contrast ratios. Partners can show brand logos and accent colors but not alter ChatGPT's core interface or use promotional language. Apps should remain "conversational, intelligent, simple, responsive, and accessible," according to the documentation. A new conversational app ecosystem By opening ChatGPT to third-party apps and payments, OpenAI is taking a major step toward transforming ChatGPT from a chatbot into a full-fledged AI operating system -- one that combines conversational intelligence, rich interfaces, and embedded commerce. For developers, that means direct access to over 800 million ChatGPT users, who can discover apps "at the right time" through natural conversation -- whether planning trips, learning, or shopping. For users, it means a new generation of apps you can chat with -- where a single interface helps you book a flight, design a slide deck, or learn a new skill without ever leaving ChatGPT. As OpenAI put it: "This is just the start of apps in ChatGPT, bringing new utility to users and new opportunities for developers." There remain a few big questions, namely: 1. what happens to all the data from those third-party apps as they interface with ChatGPT and its users...does OpenAI get access to it and can it train upon it? 2. What happens to OpenAI's once much-hyped GPT Store, which had been in the past promoted as a way for third-party creators and developers to create custom, task-specific versions of ChatGPT and make money on them through a usage-based revenue share model? We've asked the company about both issues and will update when we hear back.

ChatGPT gets apps: now you can book a trip, build slides, and make playlists without leaving the chat

Users can access apps like Spotify, Canva, and Zillow directly within conversations with the AI chatbot OpenAI is reshaping ChatGPT to be a whole platform full of apps, going well beyond the usual chatbot setup. The newest feature makes ChatGPT a conversational app store with potentially huge ramifications for how people engage with it. ChatGPT has been moving toward a more proactive approach to answering requests for a while, but the inclusion of third-party apps provided by the likes of Booking.com, Canva, Coursera, Expedia, Figma, Spotify, and Zillow, makes it so you can simply mention a task in a chat and ChatGPT can now call on the relevant services without you needing to click on a link. For instance, you could ask for a new Spotify playlist or help make a real estate listing for Zillow and have it set up on those respective platforms without leaving ChatGPT. And you don't even have to specify which app you want. Mention planning a trip, and ChatGPT might suggest the Expedia or Booking.com app. Or if you're asking about designing a logo, you might see Figma appear as part of ChatGPT's answer. ChatGPT becomes a central command center where conversations turn into actions with a single prompt. The obvious comparison here is to smartphones and the early days of the Apple App Store. But even on your phone, you have to go find and open an app to use it. With ChatGPT apps, the software comes to you based on context as much as by name. You don't open the app. The app joins the conversation. Of course, it's also a power play by OpenAI. After all, becoming a platform, OpenAI now owns the interface and possibly the app economy within it. Much like how Google controls search traffic or how Apple controls mobile distribution, OpenAI could soon determine which apps appear in ChatGPT, how they're ranked, and what it takes to be discoverable. The change is rolling out today for all ChatGPT users, except those within the EU for now. OpenAI says it plans to expand the roster of third-party partners throughout the year, aided by how developers can start building their own apps right now using the SDK. OpenAI hasn't yet laid out exactly how app developers will earn money from this new ecosystem, but a revenue model is inevitable. From the user's perspective, using one of these new ChatGPT apps looks less like installing software and more like inviting a useful guest into your chat. The first time you use a new app, ChatGPT will ask for permission and show you what data it plans to share, with a prompt to connect your accounts if needed. Once connected, these apps are interactive and will offer all sorts of help based on what you've discussed with ChatGPT. Still, if OpenAI's vision pans out, we may look back on today as the day AI stopped being a service and started becoming a storefront.

ChatGPT can now run apps and it forever changes how you get work done

Imagine a future where you don't even have to open the dedicated website or the mobile app of a service, and everything can be done within ChatGPT. Well, that future is finally here. OpenAI has today announced what it calls "apps you can chat with, right inside ChatGPT." The big shift So far, ChatGPT has relied on a system of connectors, where you could link ChatGPT with a third-party service such as Gmail, Drive, Dropbox, and Notion, among others. However, the list of supported services has been extremely limited. Now, OpenAI will let any developer build apps that can be directly accessed within the ChatGPT dialog box. More importantly, you just need to describe the task at hand and name the app to get it done. "You can discover them when ChatGPT suggests one at the right time, or by calling them by name. Apps respond to natural language and include interactive interfaces you can use right in the chat," says the company. Recommended Videos OpenAI is kicking off app support in ChatGPT with partners such as Booking.com, Canva, Coursera, Figma, Expedia, Spotify, and Zillow. These apps will be available to all users, whether they are on the free tier, or pay for a Go, Plus, or Pro subscription. The key takeaway Support for apps that can be summoned right within the ChatGPT command box and getting work done by simply describing it is quite convenient. For example, you can just type something like "Booking, show me homestays for three people over the weekend starting on September 19," and the AI chatbot will do the bidding. OpenAI has already released the SDK so that developers can start building their apps for ChatGPT atop the open Model Context Protocol⁠ (MCP) standard. In the coming months, OpenAI will start taking submissions of these apps, which will also offer monetization opportunities, just like the App Store or Google Play Store. This is a huge move as these apps essentially turn ChatGPT into its own ecosystem, just like Android and iOS. And now that ChatGPT already commands 800 million active users, it has a vast ecosystem ready to experience apps in an entirely new and conversational way.

OpenAI Just Turned ChatGPT Into an App Platform - Decrypt

Together the features shift ChatGPT from chatbot to software platform, aiming to anchor developers -- and users -- inside OpenAI's walled garden. OpenAI is turning ChatGPT into more than a chatbot. It's recasting it as a platform -- one where apps and autonomous agents run inside your conversations. At its developer conference today, the company unveiled two marquee upgrades designed to make ChatGPT the hub for both work and code. A new App SDK lets third parties build fully interactive apps that live inside chats -- so users can book flights through Expedia, design graphics in Canva, or pull listings from Zillow without ever leaving the window. And AgentKit, a drag-and-drop builder for autonomous AI agents, allows developers to design workflows that reason, retrieve data, and act on their own -- all locked within OpenAI's ecosystem. Together, the updates mark OpenAI's most aggressive push yet to transform ChatGPT from a conversational assistant into a full-blown platform -- part super-app, part operating system for reasoning. "Since our first Dev Day we've been working to open up ChatGPT to developers, and we've tried things like GPTs, and adopted standards like MCP (Model Context Protocol)," Altman said in the Opening Keynote in San Francisco earlier today. "Some of that stuff has worked, some hasn't. And today we are going to open up ChatGPT for developers to build real apps inside of ChatGPT." OpenAI's gambit is simple: If the world already runs on apps, then get people to use them inside GPT. Each "app" can respond to natural language cues, call APIs, and return structured results -- effectively giving ChatGPT plug-in-like powers without the clunkiness of a plug-in store. It's a vision borrowed from both WeChat and Salesforce AppExchange: centralize user attention, make third-party services interoperable, and turn ChatGPT into an operating system for reasoning. But unlike WeChat's mini-programs -- written by engineers for fixed tasks -- OpenAI's apps live in a fuzzier zone, where intent replaces buttons and prompts replace clicks. For OpenAI, a robust app layer means more reasons for subscribers to stay inside the ChatGPT environment and fewer to defect to rival models from Anthropic, Google, or Meta. Developers, meanwhile, are offered distribution to a user base north of 200 million, plus monetization hooks via upcoming "usage tiers" and revenue-sharing programs. Under the hood, each app plugs into ChatGPT via OpenAI's new App SDK, a toolkit that handles authentication, permissions, and semantic routing. For example, if a user says, "Find me a two-bedroom in Portland with a yard," then ChatGPT can delegate the query to Zillow, pull listings, then synthesize follow-ups -- "Would you like me to check school ratings?" Opening ChatGPT to external developers introduces the oldest problem in computing: curation. Apple and Google learned that an app store without strict review becomes a spam trap; OpenAI's review process is still opaque. Then there's the UX paradox: The more capable ChatGPT becomes, the more it risks collapsing under its own ambiguity. If half a dozen apps can answer a question, then who decides which one speaks? ChatGPT Agents. The company also unveiled "AgentKit," a platform that lets developers build and deploy autonomous AI agents using a visual drag-and-drop interface. The toolkit includes Agent Builder for workflow design, ChatKit for embeddable interfaces, Evals for performance testing, and Connectors for data integration -- all locked within OpenAI's ecosystem. The move comes as developers have spent the past years jerry-rigging autonomous systems using different tools to make their AI models execute tasks. OpenAI's solution attempts to replace that fragmented approach with a single canvas where users drag blocks, connect logic, and publish production-ready agents. The interface mimics what open-source automation tool n8n has offered for years, except with one critical difference: developers can't swap in competing models. Where n8n allows model-agnostic setups that work with Claude, Gemini, or any other AI via an API key, Agent Kit chains users exclusively to OpenAI's models. Community reactions on X ranged from "OpenAI just killed n8n" to debates about whether the restrictions outweigh the convenience. OpenAI also made Codex -- its GPT-5 model customized for coding tasks -- generally available. The coding agent has seen explosive growth, with usage jumping 10x since early August 2025, serving over 40 trillion tokens in three weeks according to Sam Altman. During the stream, Altman assured that inside OpenAI, nearly all engineers use Codex, resulting in 70% more pull requests merged weekly and automatic reviews of almost every PR. The Codex integration extends to third-party apps such as Slack, where developers can tag @Codex in channels for task delegation. It gathers context, selects environments, and provides completion links. Agent Kit components are rolling out in phases. ChatKit, a chat interface for apps built on ChatGPT, and the Agent Evaluation tool are generally available. Agent Builder remains in beta, while Connectors -- which include pre-built options for Dropbox, Google Drive, SharePoint, and Microsoft Teams -- are in beta for select API, ChatGPT Enterprise, and Edu users. The platform includes open-source Guardrails libraries in Python and JavaScript for safety controls, plus Reinforcement Fine-Tuning for models like o4-mini (generally available) and GPT-5 (private beta), with custom tool calls and graders.
