Dario Amodei， Anthropic CEO just published the much-awaited blog. "Our position on open-weights models"

• Anthropic does not support a blanket ban on open-weight models.

• Amodei's primary concern is authoritarian governments building superior military， surveillance， or repression capabilities， regardless of whether models are open.

• Powerful open-weight models carry higher misuse risks because safeguards can be removed and released weights cannot be recalled.

- Anthropic supports tighter controls on advanced chips and chipmaking equipment reaching China. It also wants action against industrial-scale distillation， which allows for cheap way to copy capabilities using far less compute.
