Open-Source LLM Compliance (Llama, Mistral, Self-Hosted)

Obligations for deployers hosting open-weight models on private cloud infrastructure.

Written by EU AI Compliance Engineering Team

1. Do Open-Source Models Fall Under Article 50?

Yes. While open-weight models enjoy certain research exemptions under Article 2(12), deployers who integrate self-hosted open-weight LLMs (such as Llama 3 or Mistral 7B) into public-facing web applications remain fully subject to Article 50 transparency obligations.
