Weighting prompts: how is it supposed to work?

[salamanders]

I was trying to build up a cartoon for a school of a black panther wearing a backpack

1. Dall-E does a great job: "Cartoon of a panther wearing a school backpack. The panther is walking into a middle school excited for the first day of class"
2. and I was attempting the same in SD. black panther wearing a backpack was very Disney, Wakanda Forever! Chadwick Boseman wearing a backpack.
3. So I started weighting the terms, and black panther:1.0 wearing:1.0 a backpack:0.9 is a mess! Random people with t-shirts with a black panther on it.

• Is there a limit to the weights? Is :1.0 breaking it?
• I'm trying bumping up the scale from default 7.5 to 8.5 as per this huggingface article
• And ddim_steps from 50 to 75

Still nuts. black panther:0.9 wearing:0.9 a backpack:0.9 white background clipart

I was told in another thread the weight acts as a separator, so your prompt (minus weights) becomes "black panther, wearing, a backpack, white background clipart". I believe 1.0 is also the default weight, so there's no need to specify that.

"Black panther" is obviously triggering on the movie, so you could try just "panther" (many people who use the term panther assume it means black anyway), or specify black elsewhere, or "black furred panther" and so on. Maybe even "a black panther" would reduce the hits for movie Black Panther.

Out of curiosity, are negative weights also supported?

And a very basic question: is "no weight" the same as "some words:0.5"?

I'm definitely not an expert, but I believe negative weights are not supported. According to the code comments, "no weight" is equivalent to 1.0.
