Google DeepMind Open-Sources SynthID Bio to Watermark AI-Designed Proteins

AI safety is extending from text and images into biology, with a provenance method that survives without degrading protein function.

Google DeepMind has introduced SynthID Bio, a method to watermark AI-designed proteins, and open-sourced it for biosecurity provenance, per @marcopapa99. The key technical claim is that the watermark embeds provenance "without degrading protein function" — meaning a designed protein can carry a traceable signature while still working as intended.
