OpenAI Unveils ‘Daybreak’ Amid Rising AI Cybersecurity Race

As concerns around AI-driven cyber threats continue to grow worldwide, OpenAI has introduced “Daybreak,” a new cybersecurity-focused initiative designed to strengthen digital defence systems using advanced artificial intelligence tools. The announcement comes only weeks after Anthropic revealed Claude Mythos, an AI model that sparked global debate over the future risks of AI-powered hacking capabilities.

OpenAI CEO Sam Altman announced the initiative on X, stating, “OpenAI is launching Daybreak, our effort to accelerate cyber defense and continuously secure software.”

The launch is being viewed by many in the tech industry as OpenAI’s response to Anthropic’s Claude Mythos, an unreleased AI model that reportedly demonstrated highly advanced cybersecurity capabilities. Mythos raised alarm among governments and technology firms due to concerns that such systems could potentially exploit vulnerabilities across software platforms and operating systems.

Unlike Anthropic’s restricted rollout strategy, OpenAI appears to be taking a broader collaborative approach. Altman said the company is willing to “start working with as many companies as possible” to improve cybersecurity preparedness. OpenAI also revealed that it is already collaborating with major technology players including Cloudflare, Oracle and Cisco.

According to OpenAI, Daybreak has been designed around the principle that future cyber defence systems must be “resilient by design.” The company believes that as AI tools become more sophisticated, organisations will need stronger and faster defence mechanisms to counter emerging threats.

OpenAI noted that while artificial intelligence can help security teams detect vulnerabilities and validate fixes, the same capabilities could also be exploited by malicious actors. To address this challenge, Daybreak combines OpenAI’s existing AI systems with the agentic coding abilities of Codex, the company’s increasingly popular coding assistant.

The platform is intended to support several cybersecurity operations, including secure code reviews, threat modelling, patch validation and dependency risk analysis. OpenAI says these capabilities can help organisations identify and fix vulnerabilities faster while reducing security backlogs and improving automated threat detection.

Daybreak will reportedly operate through three different model tiers. GPT-5.5 will serve as the default model for general-purpose developer and knowledge work with standard safeguards. Another version, GPT-5.5 with Trusted Access for Cyber, is specifically intended for verified defensive cybersecurity operations in authorised environments. This model can assist with malware analysis, vulnerability triage, detection engineering and secure patch validation.

The most advanced offering, GPT-5.5-Cyber, has been designed for specialised and authorised workflows such as penetration testing, controlled validation and advanced red teaming. OpenAI stated that access to this version would include stricter verification systems and enhanced account-level controls.

Anthropic, meanwhile, has adopted a more limited access strategy for Claude Mythos through Project Glasswing, reportedly making the model available to only around 40 selected organisations, including Amazon and Google. Reports also suggested that some unauthorised users may have accessed the model despite these restrictions.

OpenAI added that Daybreak builds upon its earlier cybersecurity efforts, including the April launch of GPT-5.4-Cyber, which the company claimed contributed to fixing more than 3,000 vulnerabilities.
