Intern-S1 75.0 leads since July 2025 Models predict properties of inorganic materials in 13 supervised tasks built from DFT and experimental data. Scored with error or classification metrics per task.
Built for materials ML models. Intern-S models report an LLM version of its property prediction tasks, and the exact subset is not stated.

Intern-S1 leads with 75.0
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.
- 1 Intern-S1 75.0
- 2 Intern-S1-Pro 72.8

| # | Model | Score | Setting | Date | Source |
|---|---|---|---|---|---|
| 1 | Intern-S1 | 75.0 | Jul 2025 | Lab model card | |
| 2 | Intern-S1-Pro | 72.8 | Feb 2026 | Lab model card |
Number one over time
Lab claims count from the day the card came out, independent runs from the model’s release.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
