OpenAI has granted the European Union access to its advanced AI model, GPT-5.5-Cyber, for cybersecurity evaluation and potential deployment. This move, confirmed by the European Commission on May 11, 2026, positions OpenAI as a proactive partner in enhancing EU cyber defenses. The model recently showcased its capabilities by completing a complex 32-step cyberattack simulation in just 12 hours, highlighting its potential to significantly improve threat detection and response times. In contrast, Anthropic, a key competitor, has not offered similar access to its Mythos model, drawing attention from EU regulators. This disparity in engagement comes as the EU seeks to enforce the AI Act, which requires stringent oversight of high-risk AI systems, particularly in critical sectors like cybersecurity. The crypto industry, which faced $1.7 billion in cyber-related losses in 2025, stands to benefit from AI-enhanced security measures, potentially influencing regulatory and investor perspectives on AI-integrated solutions.
