Models solve 14 chemistry tasks such as name conversion, property prediction, molecule captioning, generation and reaction prediction. Each task uses its own metric on the test split.

It is an instruction-tuning dataset with a test split. Shanghai AI Lab Intern-S models report the test split as a benchmark.

Intern-S1-Pro leads with 74.8%

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

2 models have held number one in labs’ own numbers since its release in February 2024

Lab claims count from the day the card came out, independent runs from the model’s release.
