Derpibooru

Derpibooru has strict content requirements for AI art. Citing their rules:

• Do not upload purely ai generated images. AI can be used as a tool to edit or create images, such as for ai composition content, but not as the only tool. Images that were almost entirely created via prompting, including ones with simple edits or clean-up, are not what this site is for. Please check tantabus.ai if you’re interested in such content.
• ai composition images must not display any AI-related errors. See this page for details.

The tagging guidelines on Derpibooru are similar to those on Tantabus. The most important difference is that ai generated art isn't allowed on Derpibooru! Only ai composition is allowed.

In general, tagging guidelines between Derpibooru and Tantabus are almost the same except for the difference above, however they may slightly diverge as these sites evolve independently, so refer to the specific site's tagging guidelines to be sure.
