### How to Get Started

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("matouLeLoup/ECE-PRYMMAL-0.5B-FT-EnhancedMUSREnsembleV3")
tokenizer = AutoTokenizer.from_pretrained("matouLeLoup/ECE-PRYMMAL-0.5B-FT-EnhancedMUSREnsembleV3")

# Format de prompt optimal
prompt = f"""Context:
Fact 1: {fact1}
Fact 2: {fact2}

Question: {question}

Choices:
{choices}

Instructions:
1. Analyze both facts carefully
2. Connect the information
3. Choose the letter (A-H) that best answers the question
4. Explain your reasoning

Reasoned Answer:"""

# Génération
inputs = tokenizer(prompt, return_tensors="pt").to(device)
outputs = model.generate(
    **inputs,
    max_new_tokens=150,
    num_beams=5,
    temperature=0.6,
    no_repeat_ngram_size=3
)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
