Libraries

How to use RedHatAI/Qwen3.8-2.4T-A95B-NVFP4-FP8 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="RedHatAI/Qwen3.8-2.4T-A95B-NVFP4-FP8")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("RedHatAI/Qwen3.8-2.4T-A95B-NVFP4-FP8")
model = AutoModelForCausalLM.from_pretrained("RedHatAI/Qwen3.8-2.4T-A95B-NVFP4-FP8", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

RedHatAI/Qwen3.8-2.4T-A95B-NVFP4-FP8

This is a quantized version of Qwen/Qwen3.8-2.4T-A95B with MoE layers quantized to NVFP4 and attention layers quantized to FP8 block

Usage

This model is intended for deployment with vLLM. You can serve the model using

vllm serve RedHatAI/Qwen3.8-2.4T-A95B-NVFP4 \
    --data-parallel-size 8 \
    --enable-expert-parallel 8 \
    --reasoning-parser qwen3 \
    --max-num-seqs 140

NOTE: Because of the need for data parallelism, this model may use more model memory for replicated attention layers. This can lead to less memory for kv cache and cache preemption when handling large concurrency. For high concurrency tasks, consider using RedHatAI/Qwen3.8-2.4T-A95B-NVFP4.

Creation Process

This model was quantized using LLM Compressor, see https://github.com/vllm-project/llm-compressor/blob/main/docs/key-models/qwen3.5/nvfp4-moe-example.md
