 - **Diffusers**
+  - since now **SD.Next** supports **12** different model types, we've added reference model for each type in  
+    *Extra networks -> Reference* for easier select & auto-download  
+    Models can still be downloaded manually, this is just a convenience feature & a showcase for supported models  
   - new model type: [Segmind SSD-1B](https://huggingface.co/segmind/SSD-1B)  
     its a *distilled* model, this time 50% smaller and faster version of SD-XL!  
     (and quality does not suffer, its just more optimized)

Other components perform as encoders and decoders of different modalities, including a pretrained image autoencoder from Stable Diffusion, a pretrained image ViT-B/32 CLIP encoder, a pretrained text ViT-L CLIP encoder, and a GPT-2 text decoder finetuned by ourselves.",
