MetaLlama-3.1 405BVSZ.ai (Zhipu AI)GLM-4.5

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

Our Take

We recommend GLM-4.5 if you need peak intelligence and a much larger context window for full-repo analysis, or the free Llama-3.1 405B if you want zero API costs and total offline privacy. While GLM-4.5 offers superior reasoning capability (hostable locally or via API), Llama-3.1 405B runs entirely on your own local hardware. Choose GLM-4.5 for repository-scale analysis, or Llama-3.1 405B for zero-cost offline privacy and basic standalone code completion and simple functions.
WHY?
Benchmark Calculations & Evidence:
  • Reasoning Accuracy: Both models were evaluated on the GPQA Diamond benchmark. GLM-4.5 scored 79.9%, while Llama-3.1 405B scored 50.7% (+29.2% gap).
  • Coding Performance: Evaluated on different benchmarks. Llama-3.1 405B scored 89% on HumanEval (basic standalone code completion and simple functions), while GLM-4.5 scored 64.2% on SWE-bench Verified (multi-file code and clearly defined tasks).
  • Context Window: GLM-4.5 supports a 131k context window, while Llama-3.1 405B supports 131k.
  • Hosting Model: Llama-3.1 405B runs locally for $0 API costs, while GLM-4.5 is a cloud API.
