# BeautifulPrompt-v2

## 简介 Brief Introduction

我们开源了一个自动Prompt生成模型，您可以直接输入一个极其简单的Prompt，就可以得到经过语言模型优化过的Prompt，帮助您更简单地生成高颜值图像。相比[v1](https://huggingface.co/alibaba-pai/pai-bloom-1b1-text2prompt-sd), 我们提升了复杂场景下的表现以及增加了生成权重(配合sd-webui使用)的能力。

We release an automatic Prompt generation model, you can directly enter an extremely simple Prompt and get a Prompt optimized by the language model to help you generate more beautiful images simply. Compared with [v1](https://huggingface.co/alibaba-pai/pai-bloom-1b1-text2prompt-sd), we have improved the performance in complex scenarios and increased the ability to generate weights (use with sd-webui).

## 使用 Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained('alibaba-pai/pai-bloom-1b1-text2prompt-sd-v2')
model = AutoModelForCausalLM.from_pretrained('alibaba-pai/pai-bloom-1b1-text2prompt-sd-v2').eval().cuda()
raw_prompt = '1 girl'

TEMPLATE_V2 = 'Converts a simple image description into a prompt. \
Prompts are formatted as multiple related tags separated by commas, plus you can use () to increase the weight, [] to decrease the weight, \
or use a number to specify the weight. You should add appropriate words to make the images described in the prompt more aesthetically pleasing, \
but make sure there is a correlation between the input and output.\n\
### Input: {raw_prompt}\n### Output:'

input = TEMPLATE_V2.format(raw_prompt=raw_prompt)
input_ids = tokenizer.encode(input, return_tensors='pt').cuda()
outputs = model.generate(
    input_ids,
    max_new_tokens=384,
    do_sample=True,
    temperature=0.9,
    top_k=50,
    top_p=0.95,
    repetition_penalty=1.1,
    num_return_sequences=5)

prompts = tokenizer.batch_decode(outputs[:, input_ids.size(1):], skip_special_tokens=True)
prompts = [p.strip() for p in prompts]
print(prompts)
```
