Anthropic presents FlashProve, a zkSNARK-based system for cryptographic proofs of inference, letting providers prove responses came from a committed model, to support verification and compliance.
Anthropic explains how Claude agents work, applies five trustworthy-agent principles to product decisions, and describes defenses across model, harness, tools and environment, plus what industry and governments can do.
Anthropic explains why it treats LLMs as a potential biorisk source, motivating dangerous-capability evaluations and CBRN safeguards under its Responsible Scaling Policy after activating ASL-3 protections for Claude Opus 4.
Anthropic and the NNSA co-developed a classifier that separates concerning from benign nuclear-related conversations at 96% preliminary accuracy, now deployed on Claude traffic to monitor misuse.
