Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
