MiniMax H3 Progressive Sampler (staged)
Progressive-resolution sampling for MiniMax H3. Runs early steps on a smaller video latent grid, upscales the x0 estimate at each stage boundary, and finishes at the target resolution. Feed a latent already at the final size.

| Name | Type | Default | Description |
|---|---|---|---|
| guider | GUIDER | — | |
| sampler | SAMPLER | — | |
| sigmas | SIGMAS | — | |
| latent_image | LATENT | — | |
| noise_seed | INT | 00–18446744073709550000 | — |
| schedule | STRING | 0.5:0.55, 1.0:1.0 | Comma-separated 'scale:end_percent' stages, e.g. '0.5:0.55, 1.0:1.0'. scale is the spatial latent scale, end_percent is where that stage ends as a fraction of the step count. Must end with '1.0:1.0' so sampling finishes at the target resolution. Use '1.0:1.0' alone as an A/B baseline. |
| upscale_method | COMBO | bicubic | 5 options: bicubic, bilinear, area, nearest-exact, bislerp |
| verbose | BOOLEAN | true | Log per-stage grid size, token count and elapsed seconds. |
