How to use two-tiger/VRPRM-rl with Transformers:
# Use a pipeline as a high-level helper from transformers import pipeline pipe = pipeline("image-text-to-text", model="two-tiger/VRPRM-rl") messages = [ { "role": "user", "content": [ {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"}, {"type": "text", "text": "What animal is on the candy?"} ] }, ] pipe(text=messages)# pip install -U transformers accelerate # Load model directly from transformers import AutoProcessor, AutoModelForMultimodalLM processor = AutoProcessor.from_pretrained("two-tiger/VRPRM-rl") model = AutoModelForMultimodalLM.from_pretrained("two-tiger/VRPRM-rl", device_map="auto") messages = [ { "role": "user", "content": [ {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"}, {"type": "text", "text": "What animal is on the candy?"} ] }, ] inputs = processor.apply_chat_template( messages, add_generation_prompt=True, tokenize=True, return_dict=True, return_tensors="pt", ).to(model.device) outputs = model.generate(**inputs, max_new_tokens=256) print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:])) - Notebooks

| # VRPRM-rl | |
| `VRPRM-rl` is the merged process-supervised RL checkpoint released for VRPRM. | |
| It is initialized from `VRPRM-sft` and trained with GSPO-token/GRPO LoRA RL on | |
| 40K confident VisualPRM400K-derived examples. | |
| ## Training | |
| - Initialization: `VRPRM-sft` | |
| - Data: 40K train / 2K validation | |
| - Rollouts: 16 per prompt, temperature 0.8, top-p 0.95 | |
| - Reward: `0.92 * step + 0.05 * format + 0.03 * think` | |
| - Optimization: lr 1e-6, KL coefficient 0.2, 600 steps | |
| - Public artifact: end-of-run merged checkpoint | |
| ## Evaluation | |
| VisualProcessBench official no-reference protocol: | |
| | Model | Overall step macro-F1 | | |
| |---|---:| | |
| | VRPRM-rl | 69.18 | | |
| The public artifact is the end-of-run checkpoint. The run's highest RL | |
| validation reward occurred earlier; comparisons should use the exact released | |
| artifact and protocol documented in the code repository. | |
| ## Usage | |
| Use the same global-thinking stepwise protocol as `VRPRM-sft`. The model is | |
| evaluated with `benchmarks/visualprocessbench/eval_vpb_global_think.py`. | |
| ## Limitations | |
| This research model is not a general assistant and is not suitable for | |
| high-stakes automated grading without human oversight. | |
