Here is [Gwern Danbooru 2021 dataset](https://www.gwern.net/Danbooru2021) as ADDON to [2018 one](https://nyaa.si/view/1176129) with **additional 1.260.067** Danbooru images **for 01.01.2019-31.12.2021 rating:safe resized to 512x512 px** with some meta-information used for image recognition training **in zipped format, acceptible to all torrent clients.** Meta information included in "initial" JSON format for posts and "advanced" JSON for all entities (read Gwern description for details). **NOTE a BOORU CHAR dataset with 1280px samples from several imageboards:** "+" much better initial image selection, bigger image size -->> can be pleasuly viewed "+" convenient folders, verbose file naming, tags to EXIF -->> flexible subsampling using file system only "+" much more computed metadata -->> a lot of analysis or subsampling without recompute "-" uncomplete, similarities lost, less image count <<-- hard initial filter, lossy preprocessing "-" less consistent, not complete tags and imageboard metadata <<-- diverse sources, diverse retrieval methods "?" not completely SFW by design BOORU CHAR is my mainstream ([release 2021](https://nyaa.si/view/1384820) , [release 2015](https://nyaa.si/view/1468367) and [release 2022](https://nyaa.si/view/1547662) at the moment) but I'll seed Gwern sets too.
