Best forDevelopers using open-source models (Flux, SDXL, Whisper, etc).Musicians comparing AI outputs. Anyone who didn't click with Suno.VS Code users who want agentic coding without changing IDEs.Developers who want an agent, not autocomplete. Large refactors, tests, docs.

Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
