Libraries

How to use jihochoi/DR-MV3D-R-GRPO with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="jihochoi/DR-MV3D-R-GRPO")
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)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("jihochoi/DR-MV3D-R-GRPO")
model = AutoModelForMultimodalLM.from_pretrained("jihochoi/DR-MV3D-R-GRPO", 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=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

DR-MV3D (SFT + GRPO)

Official checkpoint for Dense Reward for Multi-View 3D Reasoning with Global Maps and Local Views (ECCV 2026).

Paper · Project page · Code · SFT checkpoint

DR-MV3D answers questions about a 3D scene shown from several viewpoints. This is the final model of the paper: Qwen2.5-VL-3B-Instruct fine-tuned on map-grounded reasoning traces, then optimized with GRPO under dense, verifiable rewards.

Usage

The model expects the structured task prompt it was trained with, and produces a cognitive map, per-view ego-centric maps, a reasoning chain and the answer. See the GitHub repository for the prompt format, data preparation, inference and evaluation.

python scripts/run_inference.py \
  --model-path jihochoi/DR-MV3D-R-GRPO \
  -i data/prompts/MindCube_tinybench_drmv3d.jsonl \
  -o results/tinybench_responses.jsonl \
  --image-root data --batch-size 8

The weights are a fine-tune of Qwen2.5-VL-3B-Instruct and are released under Apache-2.0, the base model's license. The code is MIT-licensed.
