Google's Official Gemma 4 QAT Q4_0 GGUFs Have Higher Precision Than Unsloth's Q4_K_XL
r/LocalLLaMA top day50 days agoCommentaryAn analysis of Gemma 4 QAT GGUF files reveals that Google's official 'Q4_0' releases actually employ a mixed-precision strategy. For smaller models like E2B and E4B, Google keeps critical token embeddings in Q6_K and certain projection weights in F16. This makes Google's Q4_0 files larger and more precise than Unsloth's 'Q4_K_XL' versions, which default to standard Q4_0 for almost all tensors.
