tokenizer = AutoTokenizer.from_pretrained("zenlm/zen-eco-coder")

messages = [{"role": "user", "content": "Write a Python function that implements binary search on a sorted list."}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt")
output = model.generate(inputs, max_new_tokens=512)
print(tokenizer.decode(output[0], skip_special_tokens=True))
