Key Points

  • Open-weight models (Llama) publish weights for self-hosting/modifying
  • Advantages: data stays in, cost at scale, customization, no lock-in
  • Cautions: self-run, follows top closed models, per-model licenses
  • Suits confidentiality/high-volume/deep-modify; API faster for convenience

The Meaning of the Open-Weight Camp

Open-weight models represented by Meta's Llama are characterized by published weights that anyone can download, modify, and run in their own environment. Their character differs greatly from closed API-only models.

Open Advantages

  • Don't send data outside: infer on your own servers/closed environment
  • Cost: at large scale it can be cheaper than API usage billing
