P: Negative prompting

[EricEm]

In the text to image part, I didn't find a place to cancel prompts like in stable diffusion. Often we have artifacts with double faces or eyes in the wrong places. It depends on the channels I think but it could be efficient and necessary to add this function. Or maybe add a basic lexicon for prompts if we have to use No in front of cancels or others basic operations.

Thank you for your job, im a teacher and i think you are the best to create an democratic useful app for commons users

Whats the corret term for "No Human"

Hello @Tom Savage,

Whats the correct term for "No Human"

It depends on what the rest of the image is. For example, if you have an area where humans might normally be but you want no humans, you might use words like "desolate" or "deserted".

If you mean something else, please explain.

A negative prompt option that specificly excludes the prompt listed there in the generated image. I find myself prompting 'no light' and it seems like firefly sees 'light' and then always adds a light to the image. With this function, which already exists in other AI generators you can be much more specific.

Being able to NOT include things in image generation would be nice. For instance: "Cat without hat" now gives a cat with a hat. Describing what is not desired in the image seems like a nice feature 🙂

Hello @Joakim38709062sei6,

Thank you for your message.

The model does not understand the concept of a word being negated by the word in front of it. So using "not [X]", "no [X]", "exclude [X]", "with no [X]", and "without [X]" does not work. As you observed, it ignores the negation word and adds to the image the thing you are trying to avoid.  You basically need to find "positive" words and phrases telling the model what you want to see rather than telling it what you do not want to see.  Such as "flat land" rather than "no mountains" or "desolate" rather than "no people".  If I am not sure how to describe something I want to exclude in a positive way, I will ask Google Gemini or ChatGPT for ideas.  Just be aware that when they give prompts, they are usually too wordy and conversational, so you have to edit them, but they are good for ideas.

Thanks,

The page linked has nothing about negative prompts.  Negative prompts like "no XXX" "don't include" don't work.  Tried creating a 55 year old character with no facial hair - tried "clean shaven", "no beard", "no hair" and more - no luck.  Firefly appears to default to men with beards.

Firefly does not have negative prompts. When you say beard or hair, it will add a beard or hair. Maybe try bald?

If I could just make it stop putting basil and parsely over every single food image.  The ability to tell it to NOT add something is very much needed.

Hello @Melodic_Flutter0D45,

I moved your message to this negative prompt thread. Please feel free to upvote this thread to signal to Adobe how much the community wants negative prompting to return.

My best,

Firefly ignores entering negatives when I don't want something: NO window in the background

Liebes Adobe-Team,

bitte erweitert das "generative Füllen" um die Möglichkeit einen Negativ-Prompt einzugeben. Damit könnte man immer wiederkehrende unerwünschte Elemente ausschließen.  Außerdem wäre es toll wenn man irgendwo ein Häkchen setzen könnte, das die Verwendung von Typografie, Wörten, Buchstaben und Schriftelementen jeglicher Art bei "generaives Füllen" ausschließt. Ich bekomme ständig solche Vorschläge von der KI, völlig egal was in der Datei zu sehen ist an der ich gerade arbeite.

A prompt like this always ignores the DO NOT parts:  

A standard size ID entry badge for an company called "Auntyfa" embossed with a sample name. Include the established date of 1/17/25. Add a photo of a angry teen onto the badge. Do not show a person wearing the badge. Do not show a person holding the badge.

Hi @FlexAce, 

Thank you for your feedback. Right now, the model doesn't understand negative prompts, so adding it to a prompt will add it to your image. You can use the parameter "[avoid=xxx]" in your prompt, where xxx is the thing you want the image to veer away from. We appreciate your patience as we make Firefly better with each feedback.
