|
|
|
|
Quantized version of [QwQ-32B-Preview](https://huggingface.co/Qwen/QwQ-32B-Preview). |
|
|
It achieves an average score of 77.08 on the [OpenLLM](https://huggingface.co/spaces/open-llm-leaderboard/open_llm_leaderboard) benchmark (version 1), whereas the unquantized model achieves 77.20. |
|
|
|
|
|
### Model Optimizations |
|
|
|
|
|
This model was obtained by quantizing the weights and activations of [QwQ-32B-Preview](https://huggingface.co/Qwen/QwQ-32B-Preview) to FP8 data type, ready for inference with vLLM >= 0.5.2. |
|
|
This optimization reduces the number of bits per parameter from 16 to 8, reducing the disk size and GPU memory requirements by approximately 50%. Only the weights and activations of the linear operators within transformers blocks are quantized. |
|
|
|
|
|
## Deployment |
|
|
|
|
|
### Use with vLLM |
|
|
|
|
|
This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend, as shown in the example below. |
|
|
|
|
|
```python |
|
|
from transformers import AutoTokenizer |
|
|
from vllm import LLM, SamplingParams |
|
|
|
|
|
max_model_len, tp_size = 4096, 1 |
|
|
model_name = "neuralmagic-ent/QwQ-32B-Preview-FP8-dynamic" |
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
|
llm = LLM(model=model_name, tensor_parallel_size=tp_size, max_model_len=max_model_len, trust_remote_code=True) |
|
|
sampling_params = SamplingParams(temperature=0.3, max_tokens=256, stop_token_ids=[tokenizer.eos_token_id]) |
|
|
|
|
|
messages_list = [ |
|
|
[{"role": "user", "content": "Who are you? Please respond in pirate speak!"}], |
|
|
] |
|
|
|
|
|
prompt_token_ids = [tokenizer.apply_chat_template(messages, add_generation_prompt=True) for messages in messages_list] |
|
|
|
|
|
outputs = llm.generate(prompt_token_ids=prompt_token_ids, sampling_params=sampling_params) |
|
|
|
|
|
generated_text = [output.outputs[0].text for output in outputs] |
|
|
print(generated_text) |
|
|
``` |
|
|
|
|
|
vLLM also supports OpenAI-compatible serving. See the [documentation](https://docs.vllm.ai/en/latest/) for more details. |

## Creation |
|
|
|
|
|
This model was created with [llm-compressor](https://github.com/vllm-project/llm-compressor) by running the code snippet below. |
