GPT 5.5 in Bloom

OpenAI's most capable model is now powering your builds.

GPT 5.5 is OpenAI's smartest model yet, released April 23, 2026. It excels at complex, multi-step tasks like writing and debugging code, and can plan and execute end-to-end with minimal guidance. In Bloom, this means faster iteration, fewer errors, and apps that come together more reliably on the first try. It also uses significantly fewer tokens to complete the same tasks, so your credits go further.

Build Universal Apps in Bloom

Preview both mobile and web while you build, toggle between them with one click, and every change updates both in real time.

Bloom now builds for the web, not just mobile. Every app you create works on iOS, Android, and the web from a single codebase. Go mobile-first, web-first, or both.

The preview panel now includes a web/mobile toggle so you can switch between a browser layout and a phone device frame while you build.

Preview switcher — Toggle between web and mobile preview

If you're building something people will use on a computer, switch to web preview and make sure the layout takes advantage of the extra space. Available now for all users on web.
