Quickstart with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/rStar-Coder-Qwen3"

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

prompt = "Explain the difference between Newtonian mechanics and quantum mechanics with examples."

messages = [
    {"role": "system", "content": "You are a scientific tutor skilled in code, math, and 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]
print(response)

Intended Use

• Scientific tutoring, computational logic, and mathematical education
• Advanced coding assistant for algorithm design, code reviews, and documentation
• Structured technical data generation across formats and fields
• STEM-focused chatbot or API for research and education tools
• Mid-resource deployment requiring high symbolic fidelity

Limitations

• Not tuned for general-purpose or long-form creative writing
• Context limitations may hinder multi-document or full codebase analysis
• Specialized in technical and symbolic tasks—general chat may underperform
• Prioritizes structured reasoning over emotional or casual tone generation
