Microsoft, Tech Companies Throw Weight Behind Spread of Open-Source AI

**Industry coalition backs open-source AI:** A coalition including Microsoft, Meta, NVIDIA, IBM, Palantir, Hugging Face, Mozilla, The Linux Foundation and others has co-signed a joint letter advocating for the release and transparent development of open-source AI models; the report outlines the coalition's positions (open model access, transparency, security-through-openness, and regulatory balance), summarizes benefits for security research and defensive tooling, and notes the dual-use risks such as enabling malicious actors and supply-chain concerns, while situating the move within ongoing EU, US, and global AI governance debates.
