STATEMENT FROM DARIO AMODEI ON OUR DISCUSSIONS WITH THE DEPARTMENT OF WAR

Anthropic believes in the importance of using AI to defend the US and other democracies and to defeat its autocratic adversaries. This is why it has worked proactively to deploy its models to the Department of War and the intelligence community. However, it also acknowledges that, in some cases, AI can undermine, rather than defend, democratic values. Two such use cases are mass domestic surveillance and full autonomous weapons. Anthropic has refused to accede to the Department of War's request to remove safeguards in its models. It will help the Department transition to another provider to avoid any disruption to ongoing military planning should it decide to offboard Anthropic.

NEXT-TOKEN PREDICTOR IS AN AI'S JOB, NOT ITS SPECIES

Overemphasizing next-token prediction is a confusion of levels. On the levels where AI is a next-token predictor, humans are also next-token predictors. On the levels where humans are not next-token predictors, AI isn't one either. While AI was shaped by next-token prediction, the inside of its thoughts probably looks like a world-model, the same as a human's.

BUILDING INTERACTIVE WORLDS

Real‑time interactive environments require tight integration between simulation engines, agent AI, and live user input to create dynamic, persistent worlds. State management, sensory abstraction, behavior logic, and rendering pipelines must work in concert to support scalable multi‑user interaction. Predictable agent behavior and efficient event propagation are core requirements for responsive, interactive experiences.
