 # Hypernetworks
 Fine tuning hypernetworks to help with various aspects of image generation. 
 
-**HN_ssportrait_rc_v1_no-helmet_finetune_v1:** Hypernetwork finetuned on the full data set minus portraits with face covering helmets, should promote much cleaner facial detail and image quality while still providing for a decent range of helmet generation. Negative prompting for helmet can also help if you find helmets are still generated too frequently.
+**HN_ssportrait_v2_1.5_13431.pt:** Hypernetwork finetuned for the 1.5 trained model on the full data set it greatly improves overall accuracy of the the generated portraits. I highly recommend using this along with the 1.5 model for all portrait generation.

+**HN_ssportrait_rc_v1_no-helmet_finetune_v1:** Hypernetwork finetuned for the 1.4 trained model using the full data set minus images with faces that are covered, should promote much cleaner facial detail and image quality while still providing for a decent range of helmet generation. Negative prompting for helmet can also help if you find helmets are still generated too frequently.
