Usage
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.
