# **Open-R1-Mini-Experimental**
The **Open-R1-Mini-Experimental** model is a fine-tuned version of **Qwen/Qwen2-VL-2B-Instruct**, specifically designed for **reasoning tasks**, **context reasoning**, and **multi-modal understanding** based on the **R1 reasoning logits data**. This model integrates a conversational approach with deep reasoning capabilities to handle complex multi-modal tasks efficiently.
#### Key Enhancements:
* **Advanced Contextual Reasoning**: Open-R1-Mini-Experimental achieves state-of-the-art performance in reasoning tasks by leveraging R1 reasoning logits data, enhancing logical inference and decision-making.
* **Understanding images of various resolution & ratio**: The model excels at visual understanding benchmarks, including MathVista, DocVQA, RealWorldQA, MTVQA, etc.
* **Long-Context Video Understanding**: Capable of processing and reasoning over videos of 20 minutes or more for high-quality video-based question answering, content creation, and dialogue.
* **Device Integration**: With strong reasoning and decision-making abilities, the model can be integrated into mobile devices, robots, and automation systems for real-time operation based on both visual and textual input.
* **Multilingual Support**: Supports text understanding in various languages within images, including English, Chinese, Japanese, Korean, Arabic, most European languages, and Vietnamese.
### Sample Inference
`Demo:` https://huggingface.co/prithivMLmods/Open-R1-Mini-Experimental/blob/main/open-r1-reasoner-doc-py/open-r1-exp.ipynb
### How to Use
```python
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info
# Load the model with automatic device placement
model = Qwen2VLForConditionalGeneration.from_pretrained(
"prithivMLmods/Open-R1-Mini-Experimental", torch_dtype="auto", device_map="auto"
)
# Recommended: Enable flash_attention_2 for better performance in multi-image and video tasks
# model = Qwen2VLForConditionalGeneration.from_pretrained(
# "prithivMLmods/Open-R1-Mini-Experimental",
# torch_dtype=torch.bfloat16,
# attn_implementation="flash_attention_2",
# device_map="auto",
# )
# Load processor
processor = AutoProcessor.from_pretrained("prithivMLmods/Open-R1-Mini-Experimental")
# Adjust visual token range for optimized memory usage
# min_pixels = 256*28*28
# max_pixels = 1280*28*28
# processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-2B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
messages = [
{
"role": "user",
"content": [
{
"type": "image",
"image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
},
{"type": "text", "text": "Analyze the context of this image."},
],
}
]
# Prepare input
text = processor.apply_chat_template(
messages, tokenize=False, add_generation_prompt=True
)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
text=[text],
images=image_inputs,
videos=video_inputs,
padding=True,
return_tensors="pt",
)
inputs = inputs.to("cuda")
# Inference
generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
```
### Buffer Handling
```python
buffer = ""
for new_text in streamer:
buffer += new_text
buffer = buffer.replace("<|im_end|>", "")
yield buffer
```
