LLaMA 3.2 1B - Distractors Generation Model

This model is designed to generate distractors (incorrect but plausible answer choices) for multiple-choice questions. It is particularly useful in educational applications where high-quality distractors are needed.

Model Details

  • Model Name: llama3.2_1B_distractors_generation
  • Architecture: LLaMA 3.2 1B
  • Developer: BirendraSharma
  • Use Case: MCQ distractor generation
  • License: [More Information Needed]

How to Use the Model

You can load the model and tokenizer using transformers and generate distractors using the following example:

Installation

Ensure you have transformers and torch installed:

pip install transformers torch

Loading the Model & Tokenizer

from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig
import torch

# Load model and tokenizer
model_path = "BirendraSharma/llama3.2_1B_distractors_generation"
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype=torch.float16, device_map="auto")

def generate_distractors(context, question, answer, instruction, model, tokenizer, max_seq_length=1024):
    """Generates distractors for a given question-answer pair."""
    model.eval()
    prompt = f"""{instruction}
    Context: '{context}'
    Question: '{question}'
    Answer: '{answer}'.
    Provide only three distractors as a comma-separated list. Do not include explanations, commentary, or additional text."""
    
    inputs = tokenizer(prompt, return_tensors="pt", padding=True, truncation=True, max_length=max_seq_length).to("cuda")
    
    generation_config = GenerationConfig(
        max_new_tokens=128,
        use_cache=True,
        temperature=0.7,
    )
    
    outputs = model.generate(**inputs, generation_config=generation_config)
    distractors_text = tokenizer.batch_decode(outputs, skip_special_tokens=True)[0][len(prompt):].strip()
    distractors = [d.strip() for d in distractors_text.split(",") if d.strip()]
    
    return ", ".join(distractors[:3])

# Example usage
context = "In physics, the concept of jerk is used to describe the rate of change of acceleration."
question = "What is the physical quantity that jerk is the rate of change of?"
answer = "Acceleration"
instruction = "Generate plausible but incorrect answer choices."

distractors = generate_distractors(context, question, answer, instruction, model, tokenizer)
print("Distractors:", distractors)


# Output: velocity, momentum, force
