KSampler (Batch Seeds)
Like KSampler but generates batch_size images at once on the GPU. Each image uses seed+i so results are individually reproducible.

Inputs (12)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| seed | INT | 00–18446744073709550000 | Base seed. Item i uses seed + i. |
| steps | INT | 201–10000 | — |
| cfg | FLOAT | 8.00–100 | — |
| sampler_name | COMBO | 44 options: euler, euler_cfg_pp, euler_ancestral, euler_ancestral_cfg_pp, heun, heunpp2, +38 | |
| scheduler | COMBO | 9 options: simple, sgm_uniform, karras, exponential, ddim_uniform, beta, +3 | |
| positive | CONDITIONING | — | |
| negative | CONDITIONING | — | |
| latent_image | LATENT | — | |
| denoise | FLOAT | 1.000–1 | — |
| batch_size | INT | 21–64 | Number of images to generate in parallel on the GPU |
| seed_mode | COMBO | incremental | incremental: seed+0, seed+1, seed+2… (each image reproducible individually). random: each item gets a unique random seed derived from the base seed. fixed: all items use the same seed (identical images, useful for testing). |
