The Globe and Mail reports in its Thursday, May 14, edition that two unnamed sources say Canada's Communications Security Establishment will soon access Microsoft-backed OpenAI's latest artificial intelligence model for cybersecurity testing following a meeting between federal officials and company staff in Ottawa. The Globe's Joe Castaldo writes that OpenAI released its latest model, called GPT-5.5, in April with strict guardrails for the public. OpenAI also has a more permissive version called GPT-5.5-Cyber that can be used to hunt for and fix vulnerabilities in software. OpenAI is rolling it out to companies and other institutions through what it calls its "trusted access" program. Experts at the CSE will be able to use the model to identify flaws in software related to critical infrastructure. Sources say OpenAI will expand access to Canadian industry over time. A number of U.S. companies are already part of OpenAI's access program, including Bank of America, BlackRock, Goldman Sachs, CrowdStrike, Palo Alto Networks and others. European firms such as Deutsche Telekom are part of the program, too. OpenAI has started expanding access to U.S. federal government departments and agencies.
