Quick note on recent QAT issues
r/LocalLLaMA top day·17 hours ago·Commentary
The post argues that recent Google QAT quantization has several implementation problems, including token embeddings being quantized to q6k instead of using a pure mode. It also claims llama-quantize has a hardcoded parameter that mismatches some optimized groups, and that 32-block groups are misaligned. The author recommends Unsloth UD Q4_K_XL as a temporary option and says they are working on a patch.
