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 of the language model are quantized. ## Deployment ### Use with vLLM 1. Initialize vLLM server: ``` vllm serve nm-testing/Qwen3-30B-A3B-FP8-block --tensor_parallel_size 4 ``` 2. Send requests to the server: ```python from openai import OpenAI # Modify OpenAI's API key and API base to use vLLM's API server. openai_api_key = "EMPTY" openai_api_base = "http://:8000/v1" client = OpenAI( api_key=openai_api_key, base_url=openai_api_base, ) model = "nm-testing/Qwen3-30B-A3B-FP8-block" messages = [ {"role": "user", "content": "Explain quantum mechanics clearly and concisely."}, ] outputs = client.chat.completions.create( model=model, messages=messages, ) generated_text = outputs.choices[0].message.content print(generated_text) ``` ## Creation This model was quantized using the [llm-compressor](https://github.com/vllm-project/llm-compressor) library as shown below.

Creation details

```python from transformers import AutoProcessor, Qwen3MoeForCausalLM from llmcompressor import oneshot from llmcompressor.modeling import replace_modules_for_calibration from llmcompressor.modifiers.quantization import QuantizationModifier MODEL_ID = "Qwen/Qwen3-30B-A3B" # Load model. model = Qwen3ForCausalLM.from_pretrained(MODEL_ID, dtype="auto") processor = AutoProcessor.from_pretrained(MODEL_ID) model = replace_modules_for_calibration(model) # Configure the quantization algorithm and scheme. # In this case, we: # * quantize the weights to fp8 with per-block quantization # * quantize the activations to fp8 with dynamic token activations recipe = QuantizationModifier( targets="Linear", scheme="FP8_BLOCK", ignore=["lm_head"], ) # Apply quantization. oneshot(model=model, recipe=recipe) # Save to disk in compressed-tensors format. SAVE_DIR = MODEL_ID.rstrip("/").split("/")[-1] + "-FP8-block" model.save_pretrained(SAVE_DIR) processor.save_pretrained(SAVE_DIR) ```

## Evaluation The model was evaluated on the OpenLLM leaderboard task, using [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness). [vLLM](https://docs.vllm.ai/en/stable/) was used for all evaluations.
