Stable Diffusion 3.5 Medium — SceneWorks MLX quant matrix
Pre-built, turnkey MLX tiers of Stability AI Stable Diffusion 3.5 Medium — the 2.5B MMDiT-X (dual-attention) mid-tier, renders up to 1440² for SceneWorks, hosted as separate downloadable artifacts so the app loads a tier directly with no on-device conversion peak (sc-8513, epic 8506).
Each subdirectory is a complete from_snapshot-loadable diffusers tree — packed/dense
transformer/ plus the dense triple text encoder (CLIP-L + CLIP-G + T5-XXL), tokenizers, and 16-ch
VAE:
| Tier | transformer/ precision |
Use |
|---|---|---|
q4/ |
Q4 (asymmetric group-affine, group-64) — default | lowest memory |
q8/ |
Q8 (asymmetric group-affine, group-64) | near-lossless |
bf16/ |
dense bf16 (the source backbone, no quantization) | highest fidelity, high-memory Macs |
Only the MMDiT transformer is quantized; the text encoders and VAE are reused dense in every tier. The packed weights auto-detect their quantization on load.
