| # Unsplash JPEG Max |
|
|
| Full-resolution Unsplash photos, fetched from the Unsplash CDN at the highest JPEG quality it serves |
| (`?fm=jpg&q=100&chromasub=444`: ≈ IJG quality 98, 4:4:4, original pixel size), plus per-photo metadata. |
| Unsplash+ (premium, watermarked) photos are **not** included. |
|
|
| | | | |
| |---|---| |
| | Images | 2,094,223 (18.0TB) | |
| | Image shards | 600 × ~30 GB (`data/train-*.tar`) | |
| | Platform metadata rows | 146,294 in 1 part(s) (`platform/part-*.parquet`) | |
|
|
| _Last updated 2026-10-05 17:02 UTC. The dataset is uploaded incrementally; new shards and parts are appended, existing files never change._ |
|
|
| ## Layout |
|
|
| - `data/train-XXXXXX.tar` — WebDataset shards. Each sample is `<photo_id>.jpg` (bytes exactly as served by the CDN) + `<photo_id>.json` |
| (list record, file info incl. sha256 / size / quality, access flags incl. `flagged`, the original's EXIF from the CDN `cdn_meta`, |
| and `napi` platform metadata when it had already been collected at download time). |
| - `metadata/index/train-XXXXXX.parquet` — one row per image of the matching shard (photo_id, size, sha256, dimensions, caption, page URL, …). |
| - `platform/part-XXXXXX.parquet` — Unsplash platform metadata (description, tags, likes/views/downloads, location, EXIF, photographer, …), |
| latest snapshot per photo; `raw_json` holds the complete original record. Coverage grows over time and is independent of the image shards; |
| join on `photo_id` = `id`. |
|
|
| ## Loading |
|
|
| ```python |
| from datasets import load_dataset |
| images = load_dataset("cver91/unsplash-jpeg-max", split="train", streaming=True) |
| index = load_dataset("cver91/unsplash-jpeg-max", "index", split="train") |
| platform = load_dataset("cver91/unsplash-jpeg-max", "platform", split="train") |
| ``` |
