Watch on YouTube ↗ Summary based on the YouTube transcript and episode description.
Fireship covers Cursor 2.0’s five new features including a proprietary Composer model, parallel agents via git worktrees, and a native browser with DevTools integration.
- Cursor reached a $9.9B valuation by forking VS Code and integrating foundation models like GPT-4/Claude.
- Cursor 2.0 ships a proprietary model called Composer, claimed to rival frontier models at significantly higher speeds.
- Composer benchmarks are internal and closed-source; it does not yet appear on LM Arena or SWE-bench.
- Git worktrees integration lets users run Claude, GPT-5, and Composer agents in parallel on the same codebase simultaneously.
- In informal UI tests, Claude produced the highest-quality output; GPT-5 lagged on design tasks; Composer was fastest and surprisingly competitive.
- New native browser with full Chrome DevTools lets users pin exact HTML elements directly into the agent chat for precise UI fixes.
