DeepSeek V4 Flash REAP K160 — GGUF

Quantized GGUF of the REAP expert-pruned DeepSeek-V4-Flash-0731 checkpoint. This is an aggressively compressed variant intended for memory-constrained inference on high-end consumer and workstation GPUs.

Why the asymmetry: routed experts dominate parameter count but fire on only a fraction of tokens. Aggressive quantization on them costs less in average quality than treating router, projections, or shared experts the same way. Keeping decision-making tensors at Q8_0 preserves behavior; crushing the experts buys the size.

Base-model context

This GGUF was derived from a K160 REAP checkpoint — 160 of 256 routed experts retained per MoE scope, top-6 routing preserved, router and indexer remapped to the retained expert IDs. Structural validation passed on the source checkpoint with 46/46 MoE scopes verified.

Requirements

Use a DeepSeek-V4-capable runtime. Generic transformers pipelines will not handle the custom MXFP4 / sparse-attention / tokenizer components.
