During a livestreamed keynote presentation on Thursday, OpenAI's president Greg Brockman introduced Daybreak for Frontline Defenders, an international program designed to equip defenders protecting essential services with frontier-class AI capabilities for cybersecurity.

The program represents an expansion of OpenAI's existing Daybreak platform, which the company describes as a governed cyber defense stack that integrates frontier models, the Codex harness, Codex Security, trusted workflows, and ecosystem partners. The underlying goal centers on enabling cyber defenders to better address cyber risks by incorporating Daybreak's governed defensive tools into their current operational environments and processes.

Daybreak for Frontline Defenders extends this work by broadening subsidized access and assistance for cyber defenders responsible for safeguarding critical infrastructure and essential services globally.

What OpenAI is offering

Through Daybreak for Frontline Defenders, OpenAI is backing a $1 billion commitment to broaden subsidized access to Daybreak cyber models, training, technical support, and partnerships. The program will serve frontline defenders both within the United States and internationally.

Within the United States, the effort includes Daybreak for America, aimed at securing critical systems including water infrastructure, electrical grids, local government networks, and financial institutions. The initiative encompasses a pilot collaboration with the Multi-State Information Sharing and Analysis Center (MS-ISAC), a cybersecurity partner serving U.S. government organizations. The partnership will focus on training and supporting cyber defenders at state, local, tribal, and territorial levels.

Additionally, OpenAI's program leverages the Daybreak Defense Network, which comprises more than 350 enterprise products and partner-operated services.

OpenAI continues its broader cyber defense push

An OpenAI representative explained to The New Stack that the new Daybreak for Frontline Defenders initiative "build[s] on a broader push to get advanced cyber capabilities into defenders' hands."

The company is actively advancing this mission. An OpenAI spokesperson disclosed this week that the organization mobilized utility companies operating across 40 states and the District of Columbia to deploy OpenAI tools for strengthening their cyber defenses.

Previously, OpenAI joined over 150 organizations spanning cybersecurity, technology, critical infrastructure, finance, and artificial intelligence to release an open letter for a global surge in cyber defense, which articulated a call for collective action on cyber defense.

On Wednesday, Sam Altman addressed the G20 Innovation Ministerial in Chapel Hill, North Carolina, emphasizing the critical need to strengthen cyber protections for critical systems and services. "I think some things are going to go very wrong with cybersecurity unless people act quite urgently," he stated, according to CNBC reporting.

The urgency reflects real-world threats already unfolding. In July, cyber actors conducted operations against U.S. water and wastewater systems, a fact confirmed by the FBI. OpenAI responded by providing affected states and utilities with $1 million in complimentary API credits, Daybreak access, and technical assistance.

According to an OpenAI spokesperson, the company's financial support allowed teams "to review code and system configurations, validate findings, develop patches, and confirm fixes without disrupting essential services."

New models, more threats — more urgency

Daybreak for Frontline Defenders builds upon OpenAI's recent intensification of cyber defense initiatives. The announcement follows OpenAI's August expansion of Daybreak, which introduced two distinct tiers: Daybreak Red and Daybreak Blue.

Daybreak Red delivers access to GPT-5.6 Cyber for sophisticated security operations, including zero-day discovery, exploit chain development, and other advanced security functions. Daybreak Blue grants approved defenders access to GPT-5.6 Sol for secure code review, malware analysis, incident response, patch validation, and vulnerability identification.

OpenAI is not alone in directing frontier models toward cyber defense objectives. As reported in May, OpenAI's Daybreak and Anthropic's Glasswing, an industry consortium built on Claude Mythos Preview, demonstrate nearly equivalent performance metrics and share several partners. Both initiatives seek to place frontier AI capabilities at the disposal of cyber defenders, though they employ different harnesses and deployment approaches.

OpenAI indicates its focus on assisting defenders in enhancing existing security workflows, including identifying and validating vulnerabilities before code deployment; investigating threats, strengthening detection capabilities, and enabling response for defensive operations; and executing authorized security assessments.

As frontier models continue advancing, the imperative to help defenders reinforce cyber defenses against mounting threats grows increasingly acute. On Thursday, OpenAI unveiled GPT-6 Astra, announcing it has reached the Critical cybersecurity threshold according to its Preparedness Framework.
