# Image Synthesis

Image synthesis is the base feature of DiffSynth Studio. We can generate images with very high resolution.

### Example: FLUX

Example script: [`flux_text_to_image.py`](./flux_text_to_image.py)

### Example: Prompt Processing

If you are not native English user, we provide translation service for you. Our prompter can translate other language to English and refine it using "BeautifulPrompt" models. Please see [`sd_prompt_refining.py`](./sd_prompt_refining.py) for more details.

Prompt: "一个漂亮的女孩". The [translation model](https://huggingface.co/Helsinki-NLP/opus-mt-en-zh) will translate it to English.

Prompt: "一个漂亮的女孩". The [translation model](https://huggingface.co/Helsinki-NLP/opus-mt-en-zh) will translate it to English. Then the [refining model](https://huggingface.co/alibaba-pai/pai-bloom-1b1-text2prompt-sd) will refine the translated prompt for better visual quality.
