# Loading CrystalChat
```python
import torch
from transformers import LlamaTokenizer, LlamaForCausalLM
tokenizer = LlamaTokenizer.from_pretrained("LLM360/CrystalChat/", trust_remote_code=True)
model = LlamaForCausalLM.from_pretrained("LLM360/CrystalChat", trust_remote_code=True)
prompt = 'int add(int x, int y) {'
input_ids = tokenizer(prompt, return_tensors="pt").input_ids
gen_tokens = model.generate(input_ids, do_sample=True, max_length=400)
print("-"*20 + "Output for model" + 20 * '-')
print(tokenizer.batch_decode(gen_tokens)[0])
