🔧 Usage
Basic Inference
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "GetSoloTech/Qwen3-Code-Reasoning-4B"
# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype="auto",
device_map="auto"
)
# Prepare input for competitive programming problem
messages = [
{"role": "system", "content": "You are an expert competitive programmer. Read the problem and produce a correct, efficient solution. Include reasoning if helpful."},
{"role": "user", "content": "Your programming problem here..."}
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# Generate solution
generated_ids = model.generate(
**model_inputs,
max_new_tokens=4096,
temperature=0.7,
