The hunyuanvideo-community diffusers mirror carries the full stack in
standard layout: a 17B dual-stream DiT (32.5 GB bf16), a Qwen2.5-VL text
encoder, a ByT5 glyph encoder, the 32x HunyuanImage VAE, and
guider/ocr_guider components (AdaptiveProjectedMixGuidance) that diffusers
0.39 loads natively, so the generic from_pretrained pipeline path covers
everything with no per-component assembly.
Family notes:
- The call's guidance knob is distilled_guidance_scale (there is no
guidance_scale kwarg), so cfg_kwarg routes the UI value there; real CFG
runs inside the repo's guider at its baked scale. Defaults follow the
card recipe: 50 steps, 3.25.
- 2K-native: verified live at both 1024 and 2048.
- Coexists with the HunyuanImage-3.0 structured exclusion (3.0 has no
diffusers pipeline and stays excluded with its stated reason).
- int8/fp8 dense quantization verified live (LPIPS 0.186 both vs same-seed
bf16); a short prompt does not trip the int8 torch._int_mm minimum on
this arch, so no family exclude entry is needed.
- bf16 component table for the memory planner: (32.5, 16.3, 0.8) GB.
