Alibaba Cloud (Qwen)Qwen3.6-35B-A3BVSxAIGrok 4.20
Our Take
We recommend Grok 4.20 if you need peak intelligence and a much larger context window for full-repo analysis, or the free Qwen3.6-35B-A3B if you want zero API costs and total offline privacy. While Grok 4.20 offers superior reasoning capability, Qwen3.6-35B-A3B runs entirely on your own local hardware. Choose Grok 4.20 for repository-scale analysis, or Qwen3.6-35B-A3B for zero-cost offline privacy and complex codebases, multi-file repositories, and architectural planning.
