Usage

bash

vllm serve 0xSero/Qwen3.5-76B \
  --tensor-parallel-size 4 \
  --enable-expert-parallel \
  --max-model-len 8192 \
  --trust-remote-code \
  --language-model-only \
  --dtype bfloat16

Important: Use --language-model-only flag — this is a text-only checkpoint pruned from the multimodal base model.

What is REAP?

REAP (Routing-Enhanced Activation Pruning) removes the least-activated experts from MoE models while preserving critical capabilities. It uses router activation patterns from a calibration dataset to identify dispensable experts, with special protection for safety-critical behaviors.
