🚀 Usage Examples

Basic Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "shivs28/jee_nujan_math_expert"
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code=True)

# JEE problem format
jee_prompt = '''<|problem|>
Find the number of real solutions of the equation x³ - 3x² + 2x - 1 = 0 in the interval [0, 3].

<|solution|>'''

inputs = tokenizer(jee_prompt, return_tensors="pt")
outputs = model.generate(
    **inputs, 
    max_length=800, 
    temperature=0.1,  # Low temperature for mathematical accuracy
    do_sample=True,
    pad_token_id=tokenizer.pad_token_id,
    repetition_penalty=1.05
)

solution = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(solution)

Advanced JEE Problem

complex_problem = '''<|problem|>
In triangle ABC, if a = 7, b = 8, c = 9, find:
1. The area of triangle ABC
2. The radius of the circumscribed circle
3. The radius of the inscribed circle

<|solution|>'''

# Generate comprehensive solution
inputs = tokenizer(complex_problem, return_tensors="pt")
outputs = model.generate(
    **inputs,
    max_length=1200,
    temperature=0.05,  # Very low for multi-step problems
    top_p=0.95,
    do_sample=True,
    pad_token_id=tokenizer.pad_token_id
)

⚙️ Recommended Generation Settings

For JEE Main Problems

generation_config = {
    "max_length": 800,
    "temperature": 0.1,
    "top_p": 0.95,
    "do_sample": True,
    "repetition_penalty": 1.05,
    "pad_token_id": tokenizer.pad_token_id
}

For JEE Advanced Problems

advanced_config = {
    "max_length": 1200,      # Longer for complex solutions
    "temperature": 0.05,     # Very low for accuracy
    "top_p": 0.9,
    "do_sample": True,
    "repetition_penalty": 1.1,
    "pad_token_id": tokenizer.pad_token_id
}
