The House Committee on Homeland Security will hold a closed-door briefing with Anthropic on Wednesday to discuss the company's Mythos cybersecurity model, as anxiety over artificial intelligence's national security risks continues to escalate in Washington.
A source familiar with the meeting confirmed to The Hill that the briefing will zero in on the capabilities, national security implications, and policy questions raised by Mythos. This marks at least the second such briefing the committee has scheduled with Anthropic in recent weeks, following the limited release of the model that sent shockwaves through the capital.
Mythos, which Anthropic describes as its most advanced AI system to date, is designed to identify decades-old security vulnerabilities in software and infrastructure. The company claims it can help institutions spot and patch these flaws far more quickly than traditional methods. However, the model has not been released to the public, reflecting the delicate balance between its defensive potential and the risk that it could be turned into a weapon by malicious actors.
“It’s a double-edged sword,” one committee aide said, speaking on condition of anonymity to discuss the sensitive briefing. While Mythos could bolster cybersecurity defenses, it could also empower hackers to discover and exploit the same vulnerabilities, potentially causing widespread damage.
The briefing comes as the Trump White House scrambles to recalibrate its AI policy in the wake of Mythos's debut. President Trump is currently in China for bilateral talks with Chinese President Xi Jinping, where AI risks are expected to feature prominently on the agenda. The administration's earlier stance on AI vetting has shifted significantly since the model's emergence, according to sources familiar with internal discussions.
Anthropic did not respond to a request for comment by press time. The company, along with rival OpenAI, hosted similar closed briefings for the committee about two weeks ago, signaling the intensifying congressional interest in how AI models are being developed and deployed.
The closed nature of Wednesday's session underscores the sensitivity of the information, as lawmakers seek to understand both the defensive applications and the potential for misuse. Homeland Security Committee members are expected to press Anthropic on how it plans to prevent Mythos from falling into the wrong hands, and what safeguards exist to ensure its use aligns with national security interests.
Meanwhile, the broader political landscape remains fraught. In a separate development, SpaceX and Anthropic recently struck a surprising computing deal, despite earlier public attacks by Elon Musk on the AI firm. That partnership has raised eyebrows among technology watchers, adding another layer of complexity to the debate over AI governance.
As the briefing unfolds, the committee is also expected to explore how Mythos fits into the broader cybersecurity landscape, particularly as federal agencies face mounting pressure to modernize their defenses. The outcome of Wednesday's session could shape future legislation aimed at regulating advanced AI systems, with lawmakers increasingly wary of both the promise and the peril they represent.
