gemma-4-26B-A4B-it - DASH-Q 2-bit GGUF

llama.cpp GGUF files of google/gemma-4-26B-A4B-it quantized with

DASH-Q, at several 2-bit-class sizes. Every file uses only standard

llama.cpp tensor types (no tensor above 4 bits) and loads in any recent llama.cpp build.

Quality vs. F16 (KL divergence)

Raw-text perplexity is not a meaningful metric for gemma-4-it (the F16 model itself scores in the thousands on WikiText-2 while generating normally),

so quality is reported as KL divergence of the next-token distribution to F16 (llama-perplexity --kl-divergence, WikiText-2, 4 x 2048 tokens):

| Type | Model | Size | Mean KLD | Median KLD | Top-1 token agreement |
