Thats true! Since nat lang text encoders are more complex , the negatives of the stuff being encoded is rarely the opposite.

As in , the model itself (Chroma on perchance) isnt trained to comprehend negative vectors. Tho lodestones (creator of Chroma) never specified but I assume not.

Negatives are an off shoot in training that sorta worked in CLIP based models SD1.5 SDXL (Pony / illustrious) that carried over into the nat lang mod releases out of habit in the community.

It worked in CLIP models because the CLIP encoder is simple. Write 'ice cream' in CLIP and the text encoding vector will point roughly same direction no matter where in the 75 token batch 'ice cream' .

Compare that to the many number of different answers you can get from chatGPT or GROK containing the word 'ice cream' and you can see how the 512 token batch encoding of the T5 in Chroma , or Qwen encoder in Klein / Z image varies drastically depending how common words are arranged in the text.

  • Perchance chat is gonna get the site shut down I swear.

    Any forum with a buncha unhinged weirdos + underage users is trouble waiting to happen for the site. People wanna chat , do that on Lemmy or whatever other moderated forums there are IMO.

    what is the aesthetic 0 style type of art? anime screencap with a title in red text Fox-like girl holding a wrench and a knife, dressed in futuristic armor, looking fierce with yellow eyes. Her outfit is a dark green cropped jacket and a skirt-like bottom. \: title the aesthetic 0 style poster "Aesthetic ZERO"

    (Current Perchance Chroma model could be an early epoch and not changed until epoch 50 finishes training)
