In this video, Muhammad and I:

-test out Anthropic's new Claude 4.5 Sonnet model and its new interface

-we compare Claude and Codex,

-test out the new model by creating a browser based face filter app using Snapchat's face filters as an example

-we also built a fun donut visualizer inspired by Lex Friedmans donut video from 5 years ago

If you're interested in trying out this model uninterrupted and without needing to set up a technical environment, I can't recommend trying out https://sandbox.dev/home enough

and if you haven't had a chance to try it out yet, and have ideas for an iPhone app but no technical knowledge, i'd highly recommend trying out my app Vibecode: https://vibecode.go.link/lIlvc

AND to get you started with all of this, I'll send you a free guide through the link below.

This guide teaches you how to use both Claude Code and Codex to build different types of apps: https://maven.com/p/9c611e/claude-code-and-codex-guide
