GoogleGemini 3.1 ProVSGoogleGemma 4 31B
Our Take
We recommend Gemini 3.1 Pro if you need peak intelligence and a much larger context window for full-repo analysis, or the free Gemma 4 31B if you want zero API costs and total offline privacy. While Gemini 3.1 Pro offers superior reasoning capability, Gemma 4 31B runs entirely on your own local hardware. Choose Gemini 3.1 Pro for repository-scale analysis, or Gemma 4 31B for zero-cost offline privacy and scripting single-file apps or clearly defined functions.
