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