MetaLlama-3.1 8BVSOpenAIGPT-5.4
Our Take
We recommend GPT-5.4 if you need peak intelligence and a much larger context window for full-repo analysis, or the free Llama-3.1 8B if you want zero API costs and total offline privacy. While GPT-5.4 offers superior reasoning capability, Llama-3.1 8B runs entirely on your own local hardware. Choose GPT-5.4 for repository-scale analysis, or Llama-3.1 8B for zero-cost offline privacy and basic standalone code completion and simple functions.
