Usage
from transformers import AutoProcessor, Qwen2_5_VLForConditionalGeneration model_id = "SESPOIR/ReGround-Qwen2.5-VL-7B"model = Qwen2_5_VLForConditionalGeneration.from_pretrained( model_id, dtype="auto", device_map="auto",)processor = AutoProcessor.from_pretrained(model_id)
For complete two-round visual inference and evaluation, follow the
ReGround repository.
Training
Stage 1 applies full-parameter supervised fine-tuning to
Qwen2.5-VL-7B-Instruct using structured visual reasoning trajectories. Stage 2
uses GRPO to optimize self-diagnosis, answer accuracy, and output format. The
training format uses <think>, <reground>, and <answer> blocks; portable
configurations for both stages are available in the project repository.
Limitations
The model can produce incorrect reasoning or answers and may trigger visual
re-examination unnecessarily. It is intended for research use and should not
be relied on for high-stakes decisions without independent verification.
