+This model was created by merging two original LoRAs of [testLoRAs](https://huggingface.co/Ai-tensa/testLoRAs) into WD1.3.
 
 It is just a merged model.
 While this model is likely to produce good generation at medium resolution, consider using LoRAs of [testLoRAs](https://huggingface.co/Ai-tensa/testLoRAs) if it does not produce well.
 
-## Flex Waifu Rainbow
+#### v1.3.1
+
+The model is fine-tuned with self-generated images with a single word prompt "1girl" or "1boy" and generates well without much prompting.
+
+Twin LoRA has reduced the percentage of bad output without changing the style much.
+The images for the three Twin LoRAs were generated by FlexWaifu or a model merging Twin LoRA into it.
+3-5k images are used per Twin LORA, no duplicates.
+The reward value of ImageReward was used to classify the images.
+
+##### Twin LoRA
+
+When fine-tuning, we create two LoRAs, a good LoRA and a bad LoRA, and take the difference between them in order to suppress adverse effects and achieve the desired effect.
+
+**method**
+
+1. Create a set of images with the same prompt.
+2. Divide the image set into two equal parts, good and bad, according to certain evaluation criteria.
+3. Create a LoRA for each data set.
+4. Subtract the bad LoRA from the good LoRA. (Note: the dimension is twice the original LoRA)
+5. Apply differential LoRA in any weight.
+
+### Flex Waifu Rainbow
 
 This model is further fine-tuned from FlexWaifu with ~17k nijijourneyv5 tagged images of various authors published on the Internet.
 It is merged from six dim 8 LoRAs made in various settings, and FWRLoRA is the merged LoRA (dim 48).
 Most LoRAs were fine-tuned with Aspect Ratio Backetting with a maximum resolution of 1152x768 images, but some are up to 768x768 or 512x768.
 Image captions are made by BLIP and ~12k images also used WD1.4-tagger.

 ### Usage
 
 The format of the caption suggests that a short natural language sentence followed by a comma-separated tags is the most natural way to describe the prompt.
