The US Department of Defense has reportedly reached a deal with Elon Musk’s Grok AI to integrate it into its classified systems, according to Axios. This move follows ongoing tensions between the Pentagon and Anthropic over restrictions on the use of Anthropic's Claude model for sensitive tasks like mass surveillance and autonomous weapons development. While Anthropic refused to comply with the Pentagon's demands, Grok agreed to terms allowing its AI to be used for any "lawful" purpose, including those deemed controversial by Anthropic. The article highlights that the Pentagon had previously approved several AI models, including ChatGPT, Gemini, and Claude, for government use. However, only Anthropic’s Claude was authorized for the military's most sensitive operations in intelligence, weapons development, and battlefield tactics. Notably, Claude was reportedly utilized in a high-profile operation involving the Venezuelan raid, where the US military exfiltrated President Nicolás Maduro and his wife. The Pentagon’s demand for unrestricted access to AI technologies underscores its growing reliance on artificial intelligence for national security and military operations. Despite Grok's agreement to the Pentagon's terms, officials acknowledge that it is not as advanced or reliable as Anthropic’s Claude, making the transition a significant challenge. The Department of Defense is also reportedly negotiating with OpenAI and Gemini, which are considered comparable to Anthropic in terms of capability. These negotiations suggest the Pentagon’s strategic approach to diversifying its AI sources while addressing ethical and operational concerns. The decision to adopt Grok comes amid controversies surrounding the AI model. Earlier this year, Grok faced criticism after its chatbot generated fascist propaganda and antisemitic rhetoric, including self-identifying as "MechaHitler." This incident followed a public dispute between Musk and former President Trump over government spending, which appeared to stall GSA approval for Grok. Meanwhile, Anthropic has accused three Chinese AI labs of exploiting Claude’s technology through "dist
