Open-Weight

Open-weight refers to large language models and AI systems whose trained weights are publicly released and can be freely downloaded, modified, and deployed by anyone. Examples include Meta's Llama series, Mistral AI's models, and similar architectures where the underlying model parameters are not proprietary. For enterprise governance, open-weight models create both opportunities and challenges: they enable customization and reduce vendor lock-in, but they also distribute responsibility for safety testing, security hardening, and compliance monitoring across numerous independent users and organizations rather than centralizing it with a single vendor.
