GLM-5.1-FP8_dq4

This model is a DQ4 quantized version of the original model [GLM-5.1-FP8](Local Model). It was quantized locally using the mlx_lm library.

Quantization Methodology (DQ4)

This model was quantized using the dynamic DQ4 (4-bit / 5-bit / 6-bit / 8-bit mixed) approach, inspired by the methodology described in the mlx-community/Kimi-K2.5-mlx-DQ3_K_M-q8 repository.

The weights are mixed based on MLX layers:

• Expert layers (switch_mlp / mlp) are quantized to 4-bit.
• The first 5 layers are kept at higher quality (6-bit).
• Every 5th layer is medium quality (5-bit).
• All other layers (e.g. attention, normalization) remain at 8-bit to serve as the "8-bit brain".
