Our position on open-weights models

537 surprisetalk 2026-07-27 22:17:23 UTC anthropic.com Llama Share 757

The author of Anthropic does not support banning open-weights models, but instead advocates for keeping powerful chips out of authoritarian hands and requiring safety testing of all capable models. The author's primary concern is authoritarian governments building more powerful AI models than the US, and their secondary concern is powerful AI models being misused for cyberattacks or biological attacks.

A spacefilling curve is a continuous mapping from a lower-dimensional space into a higher-dimensional one, useful for solving the Travelling Salesman's Tour problem. The spacefilling curve heuristic (SFC) is fast, parallelizable, and does not need explicit distances between points, but may produce solutions 25% longer than optimum.
