🚀 Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "vsingh10/bitnet-medical-chat"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

messages = [
    {"role": "system", "content": "You are a helpful and knowledgeable medical doctor. Always provide detailed, medically accurate explanations."},
    {"role": "user", "content": "Hello doctor, I have bad acne. How do I get rid of it?"}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

outputs = model.generate(
    **inputs,
    max_new_tokens=300,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
