OpenAI Expands Trusted Access for Cyber with GPT-5.5

OpenAI has announced an expansion of its 'Trusted Access for Cyber' initiative, introducing the advanced GPT-5.5 model along with a specialized variant called GPT-5.5-Cyber. This program is designed to empower verified cybersecurity defenders by providing them with cutting-edge AI tools to accelerate vulnerability research and bolster the protection of critical infrastructure. By granting trusted access to these powerful models, OpenAI aims to demonstrate how advanced artificial intelligence can be effectively applied in high-stakes security domains. The initiative represents a significant step in bridging the gap between AI capabilities and real-world cybersecurity challenges, enabling defenders to identify and mitigate threats more efficiently than ever before.
