Cursor 2.0: Crash Course for Beginners

A hands-on walkthrough of Cursor 2.0's new features, demonstrated through a real React Native mobile app project. Key highlights include the new Composer AI model (fast, built in-house), and the multi-agent tab that lets you run the same prompt across up to four different models simultaneously (Composer, Claude Sonnet 4.5, GPT-5 Codex) and compare results. The demo involves revamping a paywall UI, with Sonnet 4.5 ultimately declared the winner despite being slower, while Composer is praised for speed. Practical tips on using image context, file references, and iterative prompting are shown throughout.
