Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "openai/gpt-oss-20b",
    device_map="auto",
    torch_dtype=torch.bfloat16,
    trust_remote_code=True
)

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("openai/gpt-oss-20b", trust_remote_code=True)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "Wildstash/dental-gpt-qlora")

# Example usage
messages = [
    {"role": "system", "content": "You are an expert dental clinician providing comprehensive patient care."},
    {"role": "user", "content": "Please evaluate this dental patient: 45M with severe tooth pain, swelling, fever 101°F."}
]

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

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=500,
        temperature=0.7,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id
    )

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

Training Data

The model was fine-tuned on 2,494 dental patient cases covering:

• Emergency dental situations
• Periodontal disease management
• Pediatric dental care
• Oral pathology evaluation
• Treatment planning and follow-up care

Performance

The fine-tuned model demonstrates improved:

• Structured clinical responses
• Evidence-based treatment recommendations
• Appropriate urgency assessment
• Patient safety considerations
• Clinical guideline adherence

Limitations

• This model is for educational/research purposes only
• Not intended for direct clinical decision-making
• Always consult with qualified dental professionals
• May not cover all dental specialties or rare conditions
