102 organic chemists shown real vs AI-generated molecules. Couldn't tell them apart — 62% accuracy ≈ random. That's CoCoGraph: graph diffusion with 100% chemical validity, 534K params vs 4.6M for comparable models. Constraints in the math, not the model.

The collaborative constrained graph diffusion model CoCoGraph generates novel molecules that are guaranteed to be valid and more realistic than state-of-the-art outputs, while achieving faster perform...
