How To Gen
Edit a post
Insert an image block
Click the “KaiGen” button in the block toolbar
Put a prompt into the input box
Click the Generate Image button
View/Edit the inserted image block (the alt text contains the prompt)

Text to image generation times vary by quality, low quality can be ~1 second, medium quality ~10 seconds, and high quality ~30 seconds or more.
Image to image generation times can take up to 2 minutes.
