+# PathReasoner-R1
+
+Model weights for the paper *PathReasoner-R1: Empowering Pathology Vision Language Models with Structured Diagnostic Reasoning*.
+
+## Overview
+
+PathReasoner-R1 is a pathology vision-language model trained to perform structured diagnostic reasoning over histopathology images. The model produces step-by-step reasoning grounded in a medical knowledge graph enabling clinically valid interpretations.
