Caveat: 75 GB peak fits both Ultras but check m1 headroom under load.
## 2026-07-19 — Hunyuan mlx-tune e2e (T1+T3+T4, HY3D_MLX_COMPILE=1, m3ultra)
anatomy bench image, defaults (50 steps, octree 256): shape 146s + tex 101s
= **246s total, 17.5GB peak** vs recorded defaults baseline 260s (149+112).
**1.06× e2e** — texture stage carries the win (112→101s = T4 fused DINO
+ T1 UNet compile); shape delta noise-level. Caveat: baseline row used a
different input image; same settings though. Next lever: Target 2
whole-DiT compile (unblocked by T3).
