Updates

6/2/2026: I've updated all of the quants to include the updated GGUF conversion + MTP heads (as Q8_0)

Description

This repo contains specialized MoE-quants for Step-3.7-Flash. 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.
