Bio-structure watermarking for open-weight AlphaFold 3: design tradeoffs revealed

Researcher David Stutz shares first-hand design details of a protein-structure watermarking approach:
- The solution targets the open-weight AlphaFold 3 model, which is why no multi-bit watermarking is offered
- They argue SynthID Bio-structure is simpler than FoldMark-style pipelines: it skips encoder-decoder pre-training and two-stage training by reusing one of AlphaFold 3's fine-tuning stages
- Since both FoldMark and this method require fine-tuning, the overall pipeline stays leaner
