The self-host standard

Llama 3 70B is Meta's workhorse open-weight model and the backbone of the open inference ecosystem. With 8B, 70B, and 405B sizes, it lets companies run frontier-grade chat fully on their own hardware β€” no per-call API bills, no data leaving the building. Paired with Ollama, vLLM, or Groq, it powers private assistants, RAG pipelines, and on-prem copilots across regulated industries.

Who it's for: Enterprises with data-residency needs, indie devs running local models, and anyone building on open inference.

βœ— What doesn't

  • You run the infra
  • 70B needs serious GPUs to serve fast
  • Not as strong as frontier closed models
  • Quality varies by quantization
