ChatGPT Sites turns a chat into a hosted app with logins and storage
Describe it, publish it — apps and games with real logins and saved state, hosted on your domain. Plus an open AI LEGO modeler and Claude Code mods.

A chat that ships a real app, not a mockup
ChatGPT Sites now builds, hosts, and shares websites, apps, and games with built-in storage (visitors save progress and uploaded files), ‘Sign in with ChatGPT’ auth, free hosting, and a custom domain you own. It’s in public beta on Plus, Pro, Business, Enterprise, and Edu — not Free or Go — so you can stand up a working client portal, calculator, or game with real logins and saved state without touching a deploy pipeline.
Weekend build: an open AI LEGO modeler
ldraw-nova (AGPL-3.0) is an agent that turns a prompt into a buildable LEGO model — LDraw CAD source, glTF/GLB for Blender, rendered images, even a Quest 3 VR view. It drives Claude Opus 5.5 or GPT-6 Astra and has them write Python that emits valid LDraw instead of guessing geometry, so the bricks actually connect.
Claude Code plugins can now rewire the agent
Claude Code 2.1.287 adds Claude Mods — plugins that modify deeper behavior, not just add slash-commands — plus a built-in ‘You Should Know’ agent (enable with /plugin enable cc-plugin-you-should-know@builtin) that flags things you or Claude might miss. Auto-mode also now compacts very long sessions instead of prompting on every tool call.
