# Qwen3-4B-Chemical-RLSD-TR
This repository contains the Qwen3-4B `Chemical` `RLSD_TR` batch-size-32 run.
The repository root contains the best validation checkpoint, selected by validation `mean@16`. `checkpoints/last/` contains the final checkpoint. For this run, best and final are both `global_step_100`.
## Performance
| Dataset | Method | Base model | Train batch size | Best val mean@16 | Best checkpoint | Final val mean@16 | Final checkpoint |
|---|---|---|---:|---:|---:|---:|---:|
| Chemical | RLSD_TR | Qwen3-4B | 32 | 68.96% | 100 | 68.96% | 100 |
