## The human problem

Biology depends on interacting molecules, not isolated proteins.

## The prior constraint

Different types of molecular complexes often required different modeling tools.

## AI’s actual role

A diffusion-based model predicted joint molecular structures.

## The documented result

The work improved performance across several interaction benchmarks.

## Why it may matter

Researchers gained hypotheses about molecular partnerships.

## Limitations

Structural predictions are not proof of binding, biological function, or clinical efficacy.

## Unresolved questions

Validate predictions experimentally.
