Updates / Notes

  • 10/03/2026: I've re-quanted all of the models to include MTP, please re-download.
  • 09/02/2026: Added the PLEQ4_0 for IQ2_S and IQ3_S
  • 09/01/2026: The original quants all have Q8_0 for the engram embedding tensors, and I've uploaded three variants with Q4_0 for the embedded tensors. The only difference is the Q8_0 vs Q4_0 for those tensors. I'm leaving the original quants up for those who want to use the Q8_0 PLE's.

This repo contains specialized MoE-quants for Qwen/Qwen3.8-Flash-Next. The idea being that given the huge size of the FFN tensors compared to the rest of the tensors in the model, it should be possible to achieve a better quality while keeping the overall size of the entire model smaller compared to a similar naive quantization. To that end, the quantization type default is kept in high quality and the FFN UP + FFN GATE tensors are quanted down along with the FFN DOWN tensors.
