🚀 Quick Start

Installation

pip install transformers accelerate

Usage Example

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "Kenan023214/PyroNet-v2"

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    device_map="auto"
)

# Example conversation
messages = [
    {"role": "user", "content": "Hi! Can you solve the equation x^2 - 5x + 6 = 0?"}
]

# Apply chat template
inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt"
).to(model.device)

# Generate output
outputs = model.generate(
    inputs,
    max_new_tokens=256,
    temperature=0.7,
    do_sample=True
)

# Decode and print
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
