G9v3-39A5B โ€” Q2 GGUF

Fast GGUF for mainstream llama.cpp. Requires a build with G9v3 architecture support (e.g. linuxid10t/llama.cpp@feature/g9v3-support) until upstream llama.cpp merges it โ€” standard builds will not load this model.

Recipe (antirez style)

Tensor group Format
Routed expert gate / up IQ2_XXS (imatrix)
Routed expert down Q2_K
Shared experts, attention, output Q8_0
Token embeddings F16
Routers, norms, biases F32

Same strategy as Salvatore Sanfilippo's DeepSeek V4 quants: imatrix-calibrated IQ2_XXS gate/up with K-quant down routed experts, Q8_0 protection everywhere else. Imatrix: linuxid10t.

Validation

gguf-dump audit: all routed gate/up are IQ2_XXS, all down are Q2_K (native 256-wide rows, no padding needed), zero misquantized experts; attn/shexp/output Q8_0, token F16, norms/router F32. Spot ppl + KL divergence vs the Q8_0 reference on short prompts (arithmetic, Italian fact, C completion, counting, colors), CPU-only: Q8 PPL 5.21, Q2 PPL 6.77, KL 0.21, same top token 83.9%.

Usage

# needs a G9v3-enabled llama.cpp build, e.g.
# git clone -b feature/g9v3-support https://github.com/linuxid10t/llama.cpp
llama-cli -m G9v3-39A5B-Q2-IQ2_XXS-Q2_K.gguf -t 16 -c 32768

# server
llama-server -m G9v3-39A5B-Q2-IQ2_XXS-Q2_K.gguf -t 16 -c 32768 --host 0.0.0.0 --port 8080
