DeepSeek-V4-Flash Dynamic IQ1_M GGUF

This repository contains a GGUF quantized checkpoint for DeepSeek-V4-Flash using a dynamic routed-MoE IQ1_M recipe.

Quantization recipe

The routed expert recipe is:

• ffn_gate_exps: all 43 layers -> iq1_m
• ffn_up_exps: all 43 layers -> iq1_m
• ffn_down_exps: layers 0-5 -> q2_k
• ffn_down_exps: layers 6-42 -> iq1_m
• non-routed tensors are kept according to the complete tensor-type recipe.

The final validated dtype distribution was:

f16:   359 tensors
f32:   492 tensors
i32:     3 tensors
iq1_m: 123 tensors
q2_k:    6 tensors
q8_0:  345 tensors

Quantization was produced from a full routed-F16 GGUF source using an antirez imatrix and llama.cpp llama-quantize. The final command used Q8_0 as the positional base type only to activate complete per-tensor overrides:

  Q8_0 32

Runtime status

This checkpoint is intended for ongoing development of device-side IQ1_M routed-MoE inference.

Current local validation showed:

• GGUF dtype/recipe validation passed.
• Loader smoke passed with routed raw expert binding.
• IQ1_M CPU/reference reader sanity passed with finite outputs.
• Short prefill CE/rank diagnostics produced finite logits, but quality is weaker than the Q2 baseline.

Important caveat: until IQ1_M routed-MoE CUDA/native operators are implemented, runtimes that do not support IQ1_M raw blocks on device may fall back to a very slow CPU/Python reference path.
