Gazal-R1-32B-sft-merged-preview

This is a DoRA adapter fine-tuned on top of Qwen/Qwen3-32B for specialized medical reasoning tasks.

Model description

This adapter was trained using PEFT/LoRA to enhance the base model's ability to perform step-by-step clinical reasoning and medical problem-solving.

Training data

The model was fine-tuned on a synthetic, structured reasoning dataset, which contains medical questions with step-by-step reasoning and final answers.

Training procedure

The model was trained using:

LoRA with rank 256
DoRA (Weight-Decomposed Low-Rank Adaptation)
rsLoRA (Rank-stabilized LoRA)
BF16 precision training

Use cases and limitations

This model is intended for medical education and clinical reasoning training. It should NOT be used for actual medical diagnosis or treatment decisions. Always consult qualified healthcare professionals for medical advice.

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model and tokenizer
base_model_id = "Qwen/Qwen3-32B"
adapter_id = "TachyHealth/Gazal-R1-32B-sft-merged"

# Load the tokenizer and base model
tokenizer = AutoTokenizer.from_pretrained(base_model_id)
model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype="auto",
    device_map="auto",
)

# Load the LoRA adapter
model = PeftModel.from_pretrained(model, adapter_id)

# Prepare a prompt following the format during training
query = """[MEDICAL QUESTION]"""

messages = [
    {"role": "system", "content": "When solving complex medical problems, follow this specific format..."},
    {"role": "user", "content": query}
]

input_text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)

# Generate response
outputs = model.generate(
    input_ids=inputs.input_ids,
    max_new_tokens=2048,
    temperature=0.6,
    do_sample=True,
)

response = tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True)
print(response)
