The Linux Foundation has joined NVIDIA and a broad coalition of technology leaders as an inaugural partner in the Open Secure AI Alliance, a new initiative to strengthen the security of artificial intelligence (AI) through open collaboration. The Alliance aims to develop open tools, standards, and techniques that help organizations identify vulnerabilities, improve governance, and build more secure AI systems. The Linux Foundation argues that open source principles should underpin AI development, emphasizing the importance of open models and open weights, which enable organizations to download, inspect, modify, and deploy AI models on their own infrastructure. The organization maintains that transparency creates stronger defenses, allowing a wider community to identify vulnerabilities, benchmark performance, conduct red-team testing, and develop shared safeguards. The Linux Foundation also highlights the importance of AI agent harnesses, viewing open, testable, and auditable frameworks as essential to trustworthy AI systems. The Alliance brings together organizations including Adobe, Cisco, Dell Technologies, IBM, Meta, Microsoft, NVIDIA, Red Hat, Salesforce, SAP, Siemens, and Snowflake. As part of the initiative, NVIDIA is contributing the open source NVIDIA Labs Object-Oriented Agent (NOOA) framework, available through GitHub, designed to help organizations test, trace, audit, and govern AI agent behavior more effectively.
