+## Training details
+All parameters were initialized from the [stabilityai/stable-diffusion-2-1-base](sd21) model. The unet was fine tuned as follows:
+
+U-net fine-tuning:
+- 200,000 steps, learning rate = 1e-5, batch size = 992 (248 per TPU).
+- 100,000 steps, SNR gamma = 5.0, learning rate = 1e-5, batch size = 992 (248 per TPU).
+- Trained on [LAION Improved Aesthetics 6plus](laion).
