The month it took to check the model's work

Anthropic points a Mythos preview model at real cryptography and it finds two flaws humans missed — including a fingerprint trick that deletes a whole enumeration step from a meet-in-the-middle attack on reduced-round AES — but discovery took a week and verification took human researchers a month. Then MCP drops its stateful core so tool servers can finally run serverless, and Ai2 maps wildfire risk across North America in thirty hours by treating satellite pixels, not models, as the bottleneck.
