Summary
OpenAI’s Corey from developer experience unveils the next phase of the ChatGPT plugin platform at DevDay 2026, organized around discovery, experience and shipping. The directory now lists 4,000 plugins, and installations and plugin-powered conversations have grown over the past six months. OpenAI has also worked with the ecosystem on a shared plugin format called agent plugins.
On discovery, ChatGPT will suggest relevant plugins directly in conversation, for example recommending Supabase or Vercel to someone turning a website into a full-stack app. Suggestions draw on conversion, active usage and retention signals. On experience, plugin extensions let developers place their own interface in a sidebar or side panel beside the chat, sharing context with the model in both directions.
The demos include Rosalind Workbench, a life sciences plugin with an interactive 3D molecular structure viewer, and Magic Path, an AI design platform that builds a vinyl-store landing page from a voice request inside ChatGPT. The session closes with the build-and-ship path: develop a plugin with Codex, deploy it on Sites, and submit it to the directory. It is a useful overview for developers looking to reach ChatGPT users with their products.
