OpenAI Opens Submissions for Apps Using ChatGPT’s SDK, Unveiled at DevDay
Why does it matter that OpenAI is now accepting app submissions for ChatGPT? Because developers finally have a formal pathway to embed their tools directly inside the chat experience, rather than relying on external links or plug‑ins. While the SDK was first shown at the October DevDay event, it has lingered in preview, accessible only to a limited set of partners.
Here’s the thing: opening the door to broader contributions could turn ChatGPT into a hub for a variety of services—from scheduling assistants to data‑analysis widgets—without users ever leaving the conversation. The move signals OpenAI’s intent to shift from a single‑purpose chatbot toward a platform where third‑party functionality is native to the dialogue. But there’s a technical backbone that makes this possible, and it’s not just another proprietary API.
The upcoming quote explains how the underlying Model Context Protocol (MCP) underpins the new capability, and why that matters for security and interoperability.
The move builds on OpenAI's Apps SDK, which was unveiled at DevDay in October. The SDK allows users to interact directly with apps inside ChatGPT and is currently available in preview. The Apps SDK is built on the Model Context Protocol (MCP), an open standard that enables models to connect securely to external tools and services.
OpenAI's pilot partners, including Booking.com, Canva, Coursera, Figma, Expedia, Spotify and Zillow, were among the first to launch app integrations. The ecosystem has since expanded to include apps such as OpenTable, Airtable, Apple Music, Replit, Target, Agentforce Sales and others. OpenAI said all ChatGPT apps are subject to a structured review process focused on safety, privacy and transparency before publication.
Will developers adopt the new SDK quickly? OpenAI has opened a submission portal, letting creators send apps for review and monitor status through its Developer Platform. The first batch of approved apps will roll out gradually over the next year, giving users a taste of integrated functionality inside ChatChatGPT.
The Apps SDK, unveiled at DevDay in October, is still in preview, meaning it is not yet final. Built on the Model Context Protocol, an open standard designed for secure model‑app connections, the toolkit promises direct interaction with apps inside ChatGPT. Yet it remains unclear how many third‑party tools will meet the review criteria or how users will respond to the limited rollout.
The platform tracks approval, but no timeline for full availability is provided. OpenAI’s move extends its earlier SDK launch, but whether this will translate into a noticeable expansion of ChatGPT’s capabilities is still uncertain. For now, developers can experiment, submit, and await the gradual deployment schedule outlined by the company.
