At an OpenAI Dev Days keynote today, CEO Sam Altman announced that the company is launching an SDK preview that will allow developers the ability “to build real apps inside of ChatGPT.” Altman said that, starting today, the new SDK will give developers “full stack” control over app data, action triggers, and even interactive user interfaces for apps that can appear inline as part of an existing ChatGPT conversation window.
The SDK is built on the open source Model Context Protocol (MCP), Altman said. That means developers that already use MCP only need to add an HTML resource to enable ChatGPT integration, he added.
The new integration means a ChatGPT user can directly ask Figma to turn a sketch into a diagram, for instance, and get results integrated into their ChatGPT conversation. It also means that ChatGPT can suggest apps that might be suited to a more general query, like recommending and creating a Spotify playlist when someone asks for song suggestions.
