# Image Synthesis

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

### OmniGen

OmniGen is a text-image-to-image model, you can synthesize an image according to several given reference images.

|Reference image 1|Reference image 2|Synthesized image|

### Example: FLUX

Example script: [`flux_text_to_image.py`](./flux_text_to_image.py) and [`flux_text_to_image_low_vram.py`](./flux_text_to_image_low_vram.py)(low VRAM).

The original version of FLUX doesn't support classifier-free guidance; however, we believe that this guidance mechanism is an important feature for synthesizing beautiful images. You can enable it using the parameter `cfg_scale`, and the extra guidance scale introduced by FLUX is `embedded_guidance`.
