# 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](https://github.com/SceneWorks/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.
