The short answer

When you post an AI-made illustration on pixiv, mark it as an AI-generated work on the upload screen and add tags and a caption that match the content. Rules for AI works can change, so always check pixiv's official guidelines before posting.

How do you post AI illustrations on pixiv? (The upload flow)

Mark the work as AI-generated on the upload screen, add tags and a caption, then publish.

pixiv has a system that lets AI-made works be viewed separately from other works, and the upload screen has a field for whether the work is AI-generated (names and positions may change). Posting without this setting can change where the work appears or break the rules. The guidelines on AI works are updated from time to time, so read the official guidance before posting.

Prepare	What	Note
AI-generated setting	Choose the AI-related field on the upload screen	Check the name and place in the official guidance
Tags	A few tags that match the content	Use words that describe what is in the work
Caption	A description of the work, general notes on the tools used, and so on	What you write is up to you, within the rules
Age rating	All ages or a specific rating	Choose the correct one for the content
Image	Not too large, easy to view	Check the file size limit in the official guidance

Rinka's tips

A few carefully chosen pictures get more views than a long row of similar ones
One work can hold several images, so put expression variations and alternates together in one work
AI illustrations made to look like someone else's work, characters or real people easily cause rights problems, so avoid them
