Limits
Guarantee of keyword output
While fill-gen-neg-prompt suggests what not to display in the final output, it does not guarantee those keywords will not be used in the final generative fill.
Character limits
There is no direct character limit for prompt values, though we recommend keeping your image URLs under 1024 characters.
