Mitosis Generations
Every decomposition run of the Mitosis Space is logged here: the input image, the RGBA layers produced from it, and the settings used.
⚠️ Public log
The Space is public and every run is recorded in this public dataset, including images uploaded by visitors. Do not submit anything that cannot be shared publicly.
Layout
data/
metadata.jsonl # one JSON object per run
<run_id>/
input.png # exactly what the model saw (RGB(A) normalized, transparency on white)
layer_1.png .. N.png # the RGBA layers produced
Each metadata.jsonl line:
| Field | Meaning |
|---|---|
run_id |
Folder holding this run's images |
steps |
Denoising steps |
input_file_name / layer_file_names |
Paths relative to data/; the viewer turns these into the input and layer image columns |
prompt, negative_prompt |
Text the user typed; prompt is empty when the model captioned the image itself |
auto_captioned |
Whether the prompt was generated by the model |
seed, layer_count, guidance_scale, resolution |
Generation settings (resolution is a target area: 640 or 1024) |
cfg_normalize, use_en_prompt |
Toggles from Advanced Settings |
model_id |
Model that produced the layers |
seconds |
Pipeline runtime |
timestamp |

Loading
from datasets import load_dataset
ds = load_dataset("Elfsong/mitosis-generations", split="train")
ds[0]["input"] # PIL image that was decomposed
ds[0]["layer"] # list of PIL images, one per layer
Layers are produced by Qwen-Image-Layered.
