DeepMind introduces SynthID Bio to watermark AI-designed proteins
Google DeepMind introduced SynthID Bio, a method that embeds imperceptible, verifiable watermarks into AI-generated protein sequences and predicted 3D structures while preserving biological function. Laboratory tests across target proteins (including a VEGF‑A binder) reportedly showed watermarked designs matched the performance and natural diversity of unwatermarked versions, with comparisons using AF3 predicted structures and KD binding affinity.
