Quickstart with transformers

Here's how to load and use the model with the transformers library and apply_chat_template:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/Diophantus-14B-R1-Instruct"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Explain the key techniques used in robust policy optimization."
messages = [
    {"role": "system", "content": "You are an expert assistant in optimization, reinforcement learning, and general-purpose reasoning."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
