OpenAI met with 50 cyber defense practitioners across various federal agencies, state governments, and Five Eyes allies to unveil its new GPT-5.4-Cyber model.\u00a0<\/p>\n
The artificial intelligence company held an event in D.C. on Tuesday to demo the capabilities of this new cyber model, which debuted as a tiered access program last week, Axios reported.<\/a><\/p>\n The model will be deployed through a dual-track approach, with one version broadly accessible and equipped with strong safeguards, and a separate, more cyber-capable version reserved for defenders via the Trusted Access program.<\/p>\n The pilot program was announced<\/a> in February in an effort to \u201cenhance baseline safeguards for all users while piloting trusted access for defensive acceleration.\u201d\u00a0<\/p>\n The model will also be available via an \u201cintelligence-sharing partnership\u201d that includes Australia, Canada, New Zealand, and the U.K., Axios noted.<\/p>\n GPT-5.4-Cyber rivals Anthropic’s Claude Mythos Preview, a model which is used to hunt and fix software flaws in an effort to “reshape” cybersecurity.\u00a0<\/p>\n Anthropic expanded access to Mythos to more than 40 additional organizations involved in critical software infrastructure, covering both proprietary and open-source code.<\/p>\n This move comes as AI capabilities surrounding cybersecurity have reached a \u201ctipping point.\u201d Government officials have recently raised concerns that artificial intelligence tools could be misused to disrupt critical infrastructure such as financial systems or power grids.<\/p>\n Both OpenAI and Anthropic have engaged with government agencies (including defense and public-sector organizations) to deploy or evaluate AI systems in controlled settings, often with a focus on security, safety, and sensitive use cases.<\/p>\n It was recently reported that the U.S. National Security Agency (NSA) is allegedly using Anthropic\u2019s restricted artificial intelligence<\/a> model, Claude Mythos Preview, for cyber defense despite the Pentagon blacklisting the company by designating it a supply chain risk.<\/p>\n Photo: Shutterstock<\/p>\n
