OpenAI offers a new cyber weapon to U.S. Intelligence and its allies

According to a report on Axios, companies and government agencies worldwide are eager to get their hands on the most advanced artificial intelligence tools, which on one hand offer enormous advantages to cyber defenders, but on the other carry destructive potential if they fall into the hands of malicious hackers.OpenAI held a special event in Washington for approximately 50 cybersecurity experts from across the federal government, where the capabilities of its new model, GPT-5.4-Cyber, were demonstrated. The model was recently launched as part of a tiered access program, and government officials are undergoing a rigorous vetting process similar to that of commercial clients. The company now appears to be adopting a dual-track approach: Distributing a public version with strict safeguards alongside a more permissive and advanced version released exclusively to authorized defense entities.Chris Lehane, OpenAI’s Vice President of Global Affairs, noted at the event that this approach would also enable sensitive civilian bodies, such as local water utilities, to gain access to these advanced tools. Sasha Baker, the company’s Head of National Security Policy, added that OpenAI intends to establish partnerships with government offices and build channels for sharing threat intelligence across different sectors.OpenAI’s offensive move comes immediately after the launch of competitor Anthropic’s Mythos model. The two companies are now competing for access to government agencies. However, while Anthropic has refrained from publicly releasing its model due to cybersecurity risks, its deployment within government has faced significant challenges. According to Axios, the Pentagon has labeled Anthropic a “supply chain risk” following a fierce dispute over AI safety, although it is important to note that the National Security Agency (NSA) is still evaluating the model.As noted, OpenAI is conducting briefings with the “Five Eyes” countries - an intelligence alliance that includes the United St...
White House may ease Anthropic ban to allow Mythos AI use across US ...
The White House is reportedly exploring ways to soften restrictions on Anthropic, potentially allowing its powerful Mythos AI model back into government use. The move marks a shift from earlier tensions, as agencies push for access while debates over security, ethics and military applications continue to shape policy decisions.In Washington’s fast-moving artificial intelligence landscape, yesterday’s risk can quickly become today’s necessity. Just weeks after being sidelined over security concerns, Anthropic may be edging back into favour as US agencies push for access to its most advanced model yet.At the centre of this shift is Mythos, a powerful AI system that has sparked both excitement and unease within government circles. Its capabilities, particularly in automating complex cyber operations, have made it highly attractive for defence and intelligence use, even as they raise fresh concerns about oversight and control.STORY CONTINUES BELOW THIS ADNow, the White House is reportedly working on new guidance that could allow federal agencies to bypass the earlier “ supply chain risk” designation placed on Anthropic, effectively reopening the door to its technology, reports Axios.More from TechWhite House rethinks Anthropic AI ban amid demand for MythosAccording to the Axios report, officials are drafting a potential executive action that would recalibrate how the government engages with Anthropic. The move is widely seen as an attempt to soften the fallout from an earlier decision that had effectively frozen the company out of key defence contracts.The effort as a way to “save face and bring em back in”, reports Axios.While some factions within the government remain wary, others believe the standoff has become counterproductive, particularly as demand for advanced AI tools continues to grow.The urgency is being driven in part by agencies themselves. From defence to intelligence, there is increasing interest in leveraging Mythos for both offensive and defensive capabilities. Even as legal disputes continue, some parts of the government, including the National Security Agency, are already using the model under existing arrangements.The White House has also stepped up its engagement with the private sector. Meetings with industry leaders are underway, including discussions aimed at shaping best practices for deploying advanced AI systems. These sessions reportedly include detailed reviews of potential policy changes, signalling a coordinated effort to refine ...
