PRISM dataset — Stage 1 images
Transfer mirror of the PRISM dataset's Stage-1 generated images: 200,000 PNG images generated by FLUX.1-dev from Stage-0 scene designs.
This repo is a staging area. It currently holds the image half of the dataset only; the record index (entries) is not uploaded yet.
Layout
| Path | Contents |
|---|---|
prism/stage1_images/shard_0000.tar … shard_0099.tar |
100 tar shards, ~2.7 GB each (267 GB total) |
prism/stage1_images/manifest.jsonl |
one line per member: which shard it is in, its original path, and its size |
Each tar member keeps the original path of the file, so a shard can be extracted in place:
tar -xf shard_0000.tar -C <dest> # restores prism/stage1_flux_images/... as it was
To find where one image lives:
grep '"000123_02.png"' manifest.jsonl

Why shards and not 200,000 loose files
The Hub allows only 128 write requests per hour per repository. The preupload endpoint caps a batch at 1,000 paths, so uploading the images individually needs at least 200 preupload calls plus one content-batch call per 256 files plus one commit per batch — several hours of rate-limit waiting. The Hub itself recommends "fewer, larger files" for datasets this size.
The images
| Resolution | 1024 × 1024, RGB, PNG |
| Generator | FLUX.1-dev (the run's own metadata records variant: "gguf") |
| Sampling | 20–25 steps, guidance 3.5, max_sequence_length 256 |
| Naming | <seed_idx>_<variant_idx>.png, e.g. 000000_00.png |
| Seed range | seed_idx 0 – 73,999, four variants per seed |
Each image was generated from a Stage-0 scene design that specifies the
subjects, their attributes, positions and sizes; those designs are the
filtered/scenes_*.jsonl files inside the shards.
Provenance
| Source tree | <cluster>/project_outputs/PRISM/stage1_flux_images/ |
| Upstream | PRISM pipeline, Stage 1 (project_codes/PRISM/src/stage1_flux_v2.py) |
The record index is not here
The complete 200,000-entry index lives in the Stage-3 output
(stage3_entries_repaired/variant_0{0..3}/entries.jsonl, 4.7 GB) and is
not uploaded here. Note that those entries carry the earlier schema and
the earlier Florence-2 grounding, which a full audit found unfit for
training.
The per-variant metadata.jsonl files are partial (variant_00 and
variant_02 hold 16,667 and 16,666 lines against 50,000 images each) and
must not be used as an index.
