Nemotron-Cascade-2-30B-A3B — RotorQuant GGUF IQ4_XS

nvidia/Nemotron-Cascade-2-30B-A3B quantized pack, published as Nemotron-Cascade-2-30B-A3B-RotorQuant-GGUF-IQ4_XS.

Method

llama.cpp IQ4_XS quantization.

Release line

Released under the RotorQuant line. RotorQuant and TurboQuant are this project's release labels for this pack, not distinct quantization algorithms — both brand repos carry byte-identical weights. No brand-specific speedup is claimed or measured.

Modality

pipeline_tag: text-generation.

This is a Mixture-of-Experts (MoE) model — a subset of experts is active per token; total and active parameter counts differ.

This is a llama.cpp GGUF conversion of the text tower; no modality beyond pipeline_tag above is claimed or included.

This pack is a derivative of nvidia/Nemotron-Cascade-2-30B-A3B; all credit for the original model, training, and weights belongs to the upstream authors. This repo republishes a quantized conversion of those weights only.
