What they did and found
In a test with 1,500 pose pairs, many human chemists scored near random. Two AI programs using general language tools and data features reached 67% and 74% accuracy. They did better when guided by extra ideas and reward-style training.
Why it matters
The results suggest AI can help pick likely binding poses, saving time, but gains depend on data and how the model is taught.
One method let a language tool think about poses; the other used data features to feed a simple predictor.
Open-weight AI models can narrow the gap to the best systems when guided by good features and training loops, but they do not replace expert judgment.
What remains uncertain
The findings come from a single benchmark with predefined splits. Results may differ on other pose sets or in real drug-discovery pipelines.
