The repository name uses the requested `GRPO-TR` suffix, but the actual training method for this checkpoint is GRPO. The repository root contains the best validation checkpoint (`global_step_100`), selected by validation `mean@16`. `checkpoints/last/` contains the final checkpoint. For this run, best and final are the same checkpoint. ## Performance | Dataset | Method | Base model | Train batch size | Best val mean@16 | Best checkpoint | Final val mean@16 | Final checkpoint | |---|---|---|---:|---:|---:|---:|---:| | Chemical | GRPO | Qwen3-4B | 32 | 68.81% | 100 | 68.81% | 100 |  Raw result files: - `results/validation_mean16.csv` - `results/training_scores.csv` - `artifacts/config.yaml` - `artifacts/wandb-summary.json` - `artifacts/wandb-metadata.json` - `artifacts/output.log` ## Validation Mean@16 | step | val_mean16 | |---:|---:| | 10 | 0.439880952381 | | 20 | 0.505952380952 | | 30 | 0.552678571429 | | 40 | 0.590476190476 | | 50 | 0.631845238095 | | 60 | 0.648214285714 | | 70 | 0.655952380952 | | 80 | 0.665773809524 | | 90 | 0.678869047619 | | 100 | 0.688095238095 | ## Training Hyperparameters | Hyperparameter | Value | |---|---| | Base model | `Qwen/Qwen3-4B` | | Method | `GRPO` | | Train batch size | `32` | | Train max samples | `3200` | | Total training steps | `100` | | Save frequency | `10` | | Test frequency | `10` | | Rollout samples per prompt | `8` | | Validation samples per prompt | `16` | | Learning rate | `1e-6` | | vLLM GPU memory utilization | `0.8` | | Parsed train score rows | `100` | ## Usage ```python from transformers import AutoModelForCausalLM, AutoTokenizer repo_id = "SeongryongJung/Qwen3-4B-Chemical-GRPO-TR" tokenizer = AutoTokenizer.from_pretrained(repo_id, trust_remote_code=True) model = AutoModelForCausalLM.from_pretrained( repo_id, torch_dtype="auto", device_map="auto", trust_remote_code=True, ) ``` ## Source - Checkpoint: `checkpoints/datasets/sciknoweval/chemistry/qwen3gen-chemistry-GRPO-Qwen-Qwen3-4B-mbs8-train32-rollout8-lr1e-6-vllm0.8` - W&B run: `run-20260702_050732-0ozhfamy` - Full queue log: `artifacts/queue.log`
