qwen3.5b-24b-a10b IQ4_NL GGUF

Quanter's Note: Sibling of sandeshrajx/Qwen3.5-24B-A3B-REAP-0.32, this one has been passed over completely for reasoning distills, I'd be interested to see what difference 7b more active experts can make.

GGUF quantization of sandeshrajx/qwen3.5b-24b-a10b — a 24B-parameter MoE model with 10B active parameters per token. Architecture is Qwen3.5 MoE.
