## Example Usage:

```python
import ctranslate2
from transformers import AutoTokenizer

MODEL_ID = "CTranslate2HQ/Qwen3-1.7B-ct2-bfloat16"

# Load model and tokenizer from Hugging Face Hub
generator = ctranslate2.Generator(MODEL_ID, device="cuda")
tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)

# Format prompt using chat template
messages = [
    {"role": "system", "content": "You are a helpful AI assistant."},
    {"role": "user", "content": "Write a short poem about a cat."}
]

prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=False
)

# Tokenize and generate
tokens = tokenizer.convert_ids_to_tokens(tokenizer.encode(prompt))

# Do NOT use the "compute_type" parameter with AWQ models
results = generator.generate_batch(
    [tokens],
    max_length=8192,
    sampling_temperature=0.7,
    sampling_topk=50,
    compute_type="bfloat16"
)

# Decode and print response
output_ids = results[0].sequences_ids[0]
response = tokenizer.decode(output_ids, skip_special_tokens=True)
print(response)
```
