## README

# NB H3 HyperStep v0.5.1-beta.1

MiniMax H3 middle-block residual reuse accelerator.

## Node

- Display name: `NB H3 HyperStep`
- Class ID: `NBH3HyperStep`
- Default preset: `Turbo - Skip 36 Blocks`

## Presets

- `Fast - Skip 34 Blocks`: the relatively stable preset. It bypasses blocks `[8, 42)`.
- `Turbo - Skip 36 Blocks`: the default recommended preset. It bypasses blocks `[7, 43)`.
- `Extreme - Skip 38 Blocks`: the experimental maximum-speed preset. It bypasses blocks `[6, 44)` and carries increased image-quality and temporal-consistency risk.

Refresh frequency, Guard behavior, and stability limits are fixed internally for each preset. The node does not reduce sampler step count.

Actual speedup depends on resolution, frame count, VRAM offloading, and how often Guard falls back to a full refresh.

## Recommended Chain

H3 Loader -> SageAttention -> NB H3 HyperStep -> Sampler

## Compatibility

- EasyCache compatibility is experimental. Use `H3 -> Sage -> EasyCache -> HyperStep`.
- LazyCache is not supported and is rejected with a clear error.
- Detectable model Hook or patch changes clear HyperStep caches and force a full refresh.
- Dynamic model patches have not been comprehensively validated.
