Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for open-source model APIs. The default in this space.
