GoogleGemma 4 31BVSMetaLlama-3.1 8B

Analysis by:the whichllmmodel Editorial Team|Updated: June 2026

Our Take

We recommend Gemma 4 31B for superior reasoning capability, or Llama-3.1 8B for faster local inference on smaller GPU hardware. While both models run locally for zero API costs, Gemma 4 31B carries a larger parameter memory footprint. Choose Gemma 4 31B if you have the VRAM to support it, or Llama-3.1 8B for consumer-grade hardware compatibility.
WHY?
Benchmark Calculations & Evidence:
  • Reasoning Accuracy: Both models were evaluated on the GPQA Diamond benchmark. Gemma 4 31B scored 84.3%, while Llama-3.1 8B scored 30.4% (+53.9% gap).
  • Coding Performance: Evaluated on different benchmarks. Gemma 4 31B scored 80% on LiveCodeBench (scripting single-file apps or clearly defined functions), while Llama-3.1 8B scored 72.6% on HumanEval (basic standalone code completion and simple functions).
  • Hardware Footprint: Gemma 4 31B is a 30.7B parameter model requiring more VRAM, while Llama-3.1 8B is a 8B parameter model.
