from transformers import LlamaForCausalLM, LlamaTokenizer
 
model = LlamaForCausalLM.from_pretrained("meta-llama/llama-3.1-405b")
tokenizer = LlamaTokenizer.from_pretrained("meta-llama/llama-3.1-405b")
 
prompt = "Explain the concept of quantum entanglement"
input_ids = tokenizer(prompt, return_tensors="pt").input_ids
 
# Generate
output = model.generate(input_ids, max_length=100)
print(tokenizer.decode(output[0], skip_special_tokens=True))
