The House Homeland Security Committee is digging into Anthropic\u2019s AI model Mythos in a series of briefings and hearings, as questions proliferate on whether and how the federal government will make use of the technology touted for its ability to autonomously uncover cyber vulnerabilities.<\/p>\n

Wednesday brought a closed-door briefing for the House Homeland Security Committee from Anthropic. The chairman of the panel\u2019s cybersecurity subcommittee said he is planning to hold a hearing on the topic. And committee Democrats are requesting a classified briefing with Anthropic.<\/p>\n

A number of key lawmakers, including top committee Democrat Bennie Thompson of Mississippi and GOP cyber subcommittee chair Andy Ogles of Tennessee, told CyberScoop they weren\u2019t able to attend Wednesday\u2019s briefing. But one source who did attend said it was a \u201cproductive\u201d meeting.<\/p>\n

\u201cMembers on both sides were focused on preserving U.S. advantage in AI, which basically came down to preserving our edge on compute power,\u201d the source said. \u201cThey were also asking questions about whether the federal government was using Mythos, including about where CISA is and the impact of the supply chain risk designation.\u201d<\/p>\n

The Hill reported that Wednesday\u2019s briefing was led<\/a> on the Anthropic side by Logan Graham, from the company\u2019s frontier red team, and Josh Tilstra, from the firm\u2019s national security programs and policy team. It follows another recent closed briefing<\/a> with Anthropic and OpenAI for the House Homeland Security Committee.<\/p>\n

Ogles told CyberScoop he plans to hold a hearing of his subcommittee related to Mythos, but wasn\u2019t able to attend Wednesday\u2019s briefing due to scheduling conflicts. The top Democrat on Ogle\u2019s subcommittee, Delia Ramirez of Illinois, also was unable to join due to prior commitments, but she was set to receive a rundown from staff about Wednesday\u2019s briefing, her office said.<\/p>\n

There\u2019s a divide on which federal agencies are using Mythos thus far. For example: CISA reportedly isn\u2019t<\/a>, but the National Security Agency is<\/a>.\u00a0<\/p>\n

The federal divide on its use follows a Department of Defense blacklist that labeled the company a \u201csupply chain risk\u201d after Anthropic resisted pressure from the Pentagon<\/a> to use its Claude AI model in ways the company opposed. The department says it has been using Mythos<\/a> to identify cyber vulnerabilities despite the blacklist.<\/p>\n

A turf battle is brewing<\/a> within the Trump administration over testing of AI models, The Washington Post reported this week. Connecticut Rep. Jim Himes, the top Democrat on the House Intelligence Committee, said this week that it would be \u2018insane\u201d<\/a> for U.S. spy agencies not to have early access to advanced AI models.<\/p>\n

The Mythos briefing came one day after OpenAI announced its own cybersecurity initiative<\/a>.<\/p>\n
