H3 Reference Isolate
Stops the text and reference prefix attending to the denoising target, turning one square attention into two rectangular ones. Saves attention in proportion to how much of the packed sequence is references — worth most on high-resolution multi-reference edits, negligible on a plain clip. Costs no memory.

| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | A MiniMax H3 model. Passed through, patched. | |
| start_percent | FLOAT | 0.000–1 | Denoise fraction the isolation switches on at. Above 0, the references watch the early steps — where composition is decided — before being frozen. Raise this first if identity or layout drifts. |
| end_percent | FLOAT | 1.000–1 | Denoise fraction it switches off at. 1.0 keeps it on to the end. |
