OpenAI has committed $1 billion to expand subsidized access to Daybreak cyber models, training, technical support, and partnerships for frontline defenders. ^[1] OpenAI president Greg Brockman announced on Thursday the launch of Daybreak for Frontline Defenders, a global initiative designed to help defenders use frontier cyber AI to protect essential services. ^[2] OpenAI disclosed that GPT-6 Astra qualifies as a critical risk under its internal AI safety evaluation framework because it demonstrates the ability to hack many well-protected systems without human input. ^[3] OpenAI Group PBC started opening access to GPT-6 Astra, its newest and most capable large language model, on the day of the announcement. ^[4] OpenAI stated that GPT-6 Astra achieved a perfect score on ExploitBench, a benchmark that measures large language models' ability to find and exploit software vulnerabilities. ^[5] OpenAI is launching a pilot program with the Multi-State Information Sharing and Analysis Center (MS-ISAC) to train and support state, local, tribal, and territorial cyber defenders. ^[6] The initiative includes Daybreak for America to help protect critical systems for water, electricity, local government, and banking within the United States. ^[7]
