Model Card for Gemma-3-1B-it-Medical-LoRA

This model is a fine-tuned version of unsloth/gemma-3-1b-it-unsloth-bnb-4bit. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="None", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
from peft import PeftModel

# Define model and LoRA adapter paths
base_model_name = "unsloth/gemma-3-1b-it"
lora_adapter_name = "heboya8/Gemma-3-1B-it-Medical-LoRA"

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(base_model_name)

# Load base model with optimized settings
model = AutoModelForCausalLM.from_pretrained(
    base_model_name,
    torch_dtype=torch.float16,  # Use FP16 for efficiency
    device_map="cpu",         # Explicitly map to CUDA device
    trust_remote_code=True
)

# Apply LoRA adapter
model = PeftModel.from_pretrained(model, lora_adapter_name)

# Set model to evaluation mode
model.eval()

# Create text generation pipeline
generator = pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    torch_dtype=torch.float16,
    device_map="cuda",
    max_new_tokens=128,  # Limit response length as per original script
)

# Define the question
question = ("Khi nghi ngờ bị loét dạ dày tá tràng nên đến khoa nào "
          "tại bệnh viện để thăm khám?")
          
# Format input for the pipeline
input_prompt = [{"role": "user", "content": question}]

# Generate response
output = generator(input_prompt, return_full_text=False)[0]

# Print the generated text
print(output["generated_text"])
