+# <span>Introduction</span>
+
+> This Verifier is built upon **Qwen2.5-3B-Instruct**, which supports answer verification in both English and Chinese.
+
+This is a **medical verifier** designed to evaluate the correctness of LLM outputs on [medical verifiable problems](https://huggingface.co/datasets/FreedomIntelligence/medical-o1-verifiable-problem). Such verification can be utilized to enhance the medical reasoning capabilities of LLMs.
+
+
+For details, please refer to our [paper](https://arxiv.org/pdf/2412.18925) and [GitHub repository](https://github.com/FreedomIntelligence/HuatuoGPT-o1).
+Additionally, you can explore [HuatuoGPT-o1](https://huggingface.co/FreedomIntelligence/HuatuoGPT-o1-8B), our advanced medical LLM specializing in complex medical reasoning.  
+
+
+# <span>Usage</span>
+Follow the code below to utilize this model:
+```python
+from transformers import AutoTokenizer, AutoModelForSequenceClassification
+import torch.nn.functional as F
+
+# Load tokenizer and model
+model_path = 'FreedomIntelligence/medical_o1_verifier_3B_Qwen2.5'
+tokenizer = AutoTokenizer.from_pretrained(model_path)
+model = AutoModelForSequenceClassification.from_pretrained(
+    model_path, torch_dtype="auto", device_map="auto", attn_implementation="flash_attention_2", num_labels=2
+)
+
+# Evaluation template
+template = """<Model Response>
+{}
+</Model Response>
+
+<Reference Answer>
+{}
+</Reference Answer>
+
+Your task is to evaluate the model response by comparing it to the reference answer. If the model response is correct and aligns with the reference answer, output "True" . If it is incorrect or fails to select the correct option (if options are provided), output "False" . {}"""
+
+# Tokenize input and evaluate
+LLM_response = 'The answer is 25 percentage'
+ground_truth_answer = '25%'
+input_batch = tokenizer([template.format(LLM_response,ground_truth_answer,tokenizer.eos_token)], return_tensors="pt").to(model.device)
+logits = model(**input_batch,return_dict=True).logits
+probabilities = F.softmax(logits, dim=-1)
+result = "True" if probabilities[0, 1] > 0.5 else "False"
+
+print(f"Evaluation Result: {result}")
