>>3017966There's at least 3 formats you'll typically see.
First the comma delimited human readable version, like "tag1, tag2, etc." That's used by most independent UIs and sites, like local A1111/Forge/Reforge, CivitAI, Tensor.art,
Perchance.org, etc.
Second is the ComfyUI format which splits everything into nodes. This will include a ton of {} with settings between them and is much harder to read, but the prompt is still in there if you look for it. This is only used by ComfyUI.
Finally there's NAI's format, which is kind of between those two. You'll seen NovelAI prominently at the top for these. NovelAI currently has the best anime model with its v4.5 model, but is a paid site so not everyone uses it. Like with ComfyUI the prompt is still in the metadata but it's broken up into pieces, so if you want the whole thing you have to go through the metadata to find it and piece it together.
Hope that helps!
