OpenAI pledges $1B, 100-plus companies back AI cyber defense coalition

OpenAI committed $1 billion in subsidized access to its Daybreak AI cyber models, training, and technical support, prioritizing under-resourced operators of critical infrastructure: water and wastewater systems, electric grid operators, state and local governments, community banks, and nonprofits. The pledge is targeted to be consumed over six months. More than 100 companies, including OpenAI and Anthropic, signed a joint call for collective action on AI-enabled cyber defense; SpaceX and Nvidia did not sign, and AWS signed though Amazon did not fully. OpenAI is launching a pilot with the Multi-State Information Sharing and Analysis Center (MS-ISAC) to train state, local, tribal, and territorial cyber defenders on Daybreak tools. More than 35 enterprise products and partner-operated services are joining the Daybreak Defense Network. OpenAI also published its 'Defense Factory' architecture, a continuous, agent-first operation for finding, validating, and preparing vulnerability fixes, and is sharing it so other defenders can adapt it.
