Fast Anime PromptGen
This model was trained on a dataset of 80,000 safe anime prompts for 3 epochs. I fetched the prompts from the Safebooru API endpoint, but only accepted unique prompts with up_score ≥ 8 and without any blacklisted tags. I didn't release the V1 model because it often generated gibberish prompts. After trying all means to correct that behavior, I eventually figured that the cause of the gibberish prompts is not from the pipeline params, model structure or training duration, but rather from the random usernames in the training data. Here's the complete prompt preprocessing algorithm.
Text-to-image Examples
Prefix 1girl | Generated 1girl prompts | Model Anything V4
Prefix 1boy | Generated 1boy prompts | Model Anything V4
Contrastive Search
pip install --upgrade transformers
import torch
from transformers import GPT2Tokenizer, GPT2LMHeadModel, pipeline
tokenizer = GPT2Tokenizer.from_pretrained('distilgpt2')
tokenizer.add_special_tokens({'pad_token': '[PAD]'})
model = GPT2LMHeadModel.from_pretrained('FredZhang7/anime-anything-promptgen-v2')
prompt = r'1girl, genshin'
# generate text using fine-tuned model
nlp = pipeline('text-generation', model=model, tokenizer=tokenizer)
# generate 10 samples using contrastive search
outs = nlp(prompt, max_length=76, num_return_sequences=10, do_sample=True, repetition_penalty=1.2, temperature=0.7, top_k=4, early_stopping=True)
print('\nInput:\n' + 100 * '-')
print('\033[96m' + prompt + '\033[0m')
print('\nOutput:\n' + 100 * '-')
for i in range(len(outs)):
# remove trailing commas and double spaces
outs[i] = str(outs[i]['generated_text']).replace(' ', '').rstrip(',')
print('\033[92m' + '\n\n'.join(outs) + '\033[0m\n')
Output Example:

Awesome Tips
If you feel like a generated anime character doesn't show emotions, try emoticons like
;o
,:o
,;p
,:d
,:p
, and;d
in the prompt. I also usehappy smirk
,happy smile
,laughing closed eyes
, etc. to make the characters more lively and expressive.Adding
absurdres
, instead ofhighres
andmasterpiece
, to a prompt can drastically increase the sharpness and resolution of a generated image.
