MetaLlama-3.1 70BVSMetaLlama-3.1 8B

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

Our Take

We recommend Llama-3.1 70B 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, Llama-3.1 70B carries a larger parameter memory footprint. Choose Llama-3.1 70B 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. Llama-3.1 70B scored 46.7%, while Llama-3.1 8B scored 30.4% (+16.3% gap).
  • Coding Performance: Both models were evaluated on the HumanEval benchmark. Llama-3.1 8B scored 72.6%, while Llama-3.1 70B scored 80.5% (+-7.9% gap).
  • Hardware Footprint: Llama-3.1 70B is a 70B parameter model requiring more VRAM, while Llama-3.1 8B is a 8B parameter model.
