Updates

  • 09/22/26: Added 3.5, 2.5, and 2.0 BPW quants using ed's bpw-size PR. The FFNs are the primarily quantized feature, rest of the model remains in Q8_0 / Q6_K

This repo contains specialized MoE-quants for XiaomiMiMo/MiMo-V2.6-Flash-RL. 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.

The MXFP4 quant is the "full quality" version, as the model has MXFP4 experts.
