OpenAI pitches GPT-5.4-Cyber to Five Eyes, targeting national security defense

OpenAI briefed U.S. federal agencies, state governments, and Five Eyes intelligence alliance members over the past week.

The company introduced GPT-5.4-Cyber, a specialized AI model designed for defensive cybersecurity and critical infrastructure. The model identifies software vulnerabilities and reverse-engineers potential malware.

This initiative positions OpenAI against rival AI labs targeting the high-stakes national security sector. The move builds on the company's existing government-focused offerings.
