Gemma-4-26B-A4B Heretic
Quality: quantized (mixed quants per tensor, group size: 32, 9.367 bpw)
Most layers use 8-bit affine quantization with a group size 32; some layers are saved in bf16.
This is a abliterated (uncensored) version of google/gemma-4-26B-A4B-it, made using Heretic v1.2.0 with the Arbitrary-Rank Ablation (ARA) method (with row-norm preservation)
