Anthropic CEO Dario Amodei posted an update on where things stand with the Department of War. In a nutshell:

  1. Anthropic said it will challenge the White House assessment that it is a supply chain risk in court.
  2. Most existing Anthropic customers won't be affected.
  3. The tone of the most was a bit apologetic and indicated that negotiations may be going on behind the scenes.
  4. Anthropic models are being used in Iran as we speak.

"Our most important priority right now is making sure that our warfighters and national security experts are not deprived of important tools in the middle of major combat operations. Anthropic will provide our models to the Department of War and national security community, at nominal cost and with continuing support from our engineers, for as long as is necessary to make that transition, and for as long as we are permitted to do so."
