 # Model Card for BioXP
 
-This model is a 🤗 transformers model, BioXP-0.5B.
+BioXP-0.5B is a 🤗 Transformers-based model trained using our two-stage fine-tuning approach:
+
+1. Supervised Fine-Tuning (SFT): The model was initially fine-tuned on labeled data(MedMCQA) to achieve strong baseline accuracy on multiple-choice medical QA tasks.
+
+2. Group Relative Policy Optimization (GRPO): In the second stage, GRPO was applied to further align the model with human-like reasoning patterns.
+This reinforcement learning technique enhances the model’s ability to generate coherent, high-quality explanations and improve answer reliability.
