Best forDevelopers using open-source models (Flux, SDXL, Whisper, etc).Developers who want an agent, not autocomplete. Large refactors, tests, docs.Developers + power users who want control and privacy.VS Code users who want agentic coding without changing IDEs.

Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
