+# omnigen-lora-test
+
+This is a LyCORIS adapter derived from [Shitao/OmniGen-v1-diffusers](https://huggingface.co/Shitao/OmniGen-v1-diffusers).
+
+The main validation prompt used during training was:
+```
+An ugly hillbilly woman with missing teeth and a mediocre smile
+```
+
+
+## Validation settings
+- CFG: `3.0`
+- CFG Rescale: `0.0`
+- Steps: `30`
+- Sampler: `FlowMatchEulerDiscreteScheduler`
+- Seed: `42`
+- Resolution: `768x768`
+
+
+Note: The validation settings are not necessarily the same as the [training settings](#training-settings).
+
+You can find some example images in the following gallery:
+
+
+<Gallery />
+
+The text encoder **was not** trained.
+You may reuse the base model text encoder for inference.
+
+
