Libraries

How to use csfufu/Revisual-R1-Coldstart with Transformers:

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

pipe = pipeline("image-text-to-text", model="csfufu/Revisual-R1-Coldstart")
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, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("csfufu/Revisual-R1-Coldstart")
model = AutoModelForImageTextToText.from_pretrained("csfufu/Revisual-R1-Coldstart")
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]:]))

🌟 ReVisual-R1 (7B) — Open-Source Multimodal Reasoner

One cold-start, two RL stages, endless reasoning power.

🔑 Highlights

SOTA on 9 tough benchmarks covering visual–math + text reasoning.
Three-Stage SRO Training
1. Text Cold-Start — seed deep reflection
2. Multimodal RL — align vision & logic
3. Text RL — polish fluency & brevity
PAD (Prioritized Advantage Distillation) keeps gradients alive.
Efficient-Length Reward = concise, self-reflective CoT.
