The Justice Department filed its response to Anthropic’s federal lawsuit yesterday, and the central argument reframes what AI safety commitments mean under wartime pressure. Government attorneys wrote that Defense Secretary Hegseth “reasonably” determined that Anthropic staff might “sabotage, maliciously introduce unwanted function, or otherwise subvert” national security systems - framing the values embedded in an AI company’s architecture as a potential vector for operational disruption during active combat. The filing states explicitly that the Pentagon “cannot simply flip a switch” to replace Claude on classified systems while high-intensity operations are underway, and that it is actively pursuing Google, OpenAI, and xAI as alternatives. No amicus briefs have been filed in support of the government’s position; Microsoft, Google, Amazon, Apple, 22 former military officials, and more than 30 cross-competitor AI researchers are all on record opposing the designation. Judge Rita Lin has scheduled a hearing for next Tuesday.
Separately, the Pentagon disclosed plans to establish secure environments where AI companies would train military-specific models directly on classified data - a qualitative shift from current deployments where models analyze classified documents without learning from them. Mamba 3 arrived as an open-source state-space architecture whose benchmark scores exceed same-size Transformers by approximately two points on average, with computational costs that scale linearly rather than quadratically as context grows. MIT physicists published a Nature paper describing the first direct observation of superconducting electrons moving in a frictionless, wave-like oscillation inside a copper-oxide compound - a quantum behavior predicted by theory but structurally invisible until a terahertz microscope compressed long-wavelength light into a region small enough to resolve it. And Northwestern surgeons reported keeping a patient alive for 48 hours without lungs using an engineered artificial lung system, with molecular analysis of the removed tissue providing the first biological proof that some acute respiratory failure cannot recover and requires transplantation - a patient who is now, more than two years later, living normally with healthy lung function.
