Usage
Using 🤗Transformers
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
MODEL_NAME = "p1atdev/dart-v2-sft"
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
model = AutoModelForCausalLM.from_pretrained(MODEL_NAME, torch_dtype=torch.bfloat16)
prompt = (
f"<|bos|>"
f"<copyright>vocaloid</copyright>"
f"<character>hatsune miku</character>"
f"<|rating:general|><|aspect_ratio:tall|><|length:long|>"
f"<general>1girl, cat ears<|identity:none|><|input_end|>"
)
inputs = tokenizer(prompt, return_tensors="pt").input_ids
with torch.no_grad():
outputs = model.generate(
inputs,
do_sample=True,
temperature=1.0,
top_p=1.0,
top_k=100,
max_new_tokens=128,
num_beams=1,
)
print(", ".join([tag for tag in tokenizer.batch_decode(outputs[0], skip_special_tokens=True) if tag.strip() != ""]))
# vocaloid, hatsune miku, 1girl, cat ears, closed mouth, detached sleeves, dress, expressionless, from behind, full body, green theme, hair ornament, hair ribbon, headphones, high heels, holding, holding microphone, long hair, microphone, monochrome, necktie, ribbon, short dress, shoulder tattoo, simple background, sleeveless, sleeveless dress, spot color, standing, tattoo, thighhighs, twintails, very long hair, white background
Using 📦dartrs
library
This library is very experimental and there will be breaking changes in the future.
📦dartrs
is a 🤗candle
backend inference library for Dart v2 models.
pip install -U dartrs

Prompt Format
prompt = (
f"<|bos|>"
f"<copyright>{copyright_tags_here}</copyright>"
f"<character>{character_tags_here}</character>"
f"<|rating:general|><|aspect_ratio:tall|><|length:long|>"
f"<general>{general_tags_here}<|identity:none|><|input_end|>"
)
Rating tag:
<|rating:sfw|>
,<|rating:general|>
,<|rating:sensitive|>
,nsfw
,<|rating:questionable|>
,<|rating:explicit|>
sfw
: randomly generates tags ingeneral
orsensitive
rating categories.general
: generates tags ingeneral
rating category.sensitive
: generates tags insensitive
rating category.nsfw
: randomly generates tags inquestionable
orexplicit
rating categories.questionable
: generates tags inquestionable
rating category.explicit
: generates tags inexplicit
rating category.
Aspect ratio tag:
<|aspect_ratio:ultra_wide|>
,<|aspect_ratio:wide|>
,<|aspect_ratio:square|>
,<|aspect_ratio:tall|>
,<|aspect_ratio:ultra_tall|>
ultra_wide
: generates tags suits for extremely wide aspect ratio images. (~2:1)wide
: generates tags suits for wide aspect ratio images. (2:1~9:8)square
: generates tags suits for square aspect ratio images. (9:8~8:9)tall
: generates tags suits for tall aspect ratio images. (8:9~1:2)ultra_tall
: generates tags suits for extremely tall aspect ratio images. (1:2~)
Length tag:
<|length:very_short|>
,<|length:short|>
,<|length:medium|>
,<|length:long|>
,<|length:very_long|>
very_short
: totally generates ~10 number of tags.short
: totally generates ~20 number of tags.medium
: totally generates ~30 number of tags.long
: totally generates ~40 number of tags.very_long
: totally generates 40~ number of tags.
Identity tag:
<|identity:none|>
,<|identity:lax|>
,<|identity:strict|>
- This tag specifies how strictly to preserve identity of character or subject in provided tags.
none
: recommended if the specified general tags are very few. It generates tags very creatively, but sometimes ignores the condition of the general tags.lax
: recommended if you want to keep the identity of charaacters or subjects in the general tags. This tag tries not to generate tags which conflict with the input general tags.strict
: recommended if you strongly want to keep the identity of charaacters or subjects in the general tags. This tag tries not to generate tags which conflict with the input general tags more strictly thanlax
. But this is less creative, so if you don't like the result withstrict
, please trylax
ornone
.
