Kolors — MLX quantization tiers (SceneWorks)
Pre-quantized MLX turnkey tiers of Kwai-Kolors/Kolors-diffusers
for the SceneWorks native (mlx-gen) runtime. Each tier subdir is a self-contained snapshot — SDXL-style
U-Net + ChatGLM3-6B text encoder + SDXL VAE + baked fast tokenizer — that loads packed, with no
dense transient and no install-time conversion peak.
| Tier | Subdir | Size | Notes |
|---|---|---|---|
| Q4 (default) | q4/ |
~6.0 GiB | U-Net + ChatGLM3 packed 4-bit; dense VAE |
| Q8 | q8/ |
~9.7 GiB | U-Net + ChatGLM3 packed 8-bit; dense VAE |
| bf16 | bf16/ |
~17 GiB | dense 16-bit weights |
Quantization: group-wise affine, group size 64, weight-only, byte-identical to the runtime's
load-time seam. The VAE is never quantized (it runs f32). The fast tokenizer.json is derived from the
ChatGLM3 slow tokenizer (SceneWorks/kolors-chatglm3-tokenizer)
and baked into each tier.
