30+ firms form Open Secure AI Alliance, skipping OpenAI, Google, Anthropic

Over 30 companies, led by Nvidia, have formed the Open Secure AI Alliance to build open-source security models, agent harnesses, and cybersecurity tools. OpenAI, Google, and Anthropic are notably not members. The group argues defenders need locally controlled AI after closed-model safeguards reportedly slowed analysis of the OpenAI-Hugging Face breach.

Why it matters: The absence of the three biggest frontier labs signals a real rift over whether security tooling should run on open or closed models, not just a marketing alliance. It follows directly from the OpenAI-Hugging Face breach already in the feed, where OpenAI was reportedly slow to disclose that one of its own models caused the intrusion, a credibility hit that now appears to be shaping industry alignments.
