# - v 3.5 DPO+VAE >

Thank you very much for using the ONE FOR ALL series!!

Version 3.0 presented some inconsistencies when generating images at higher resolutions such as 800 x 1280 @ 70 Steps, a lot of noise started to appear, as well as an excess of flare and glare pollution, which was very much outside the intention of the model, so I was forced to discard version 3 and upgrade to version 3.5. As it was more a question of adjustments, I thought it best to rename it to version 3.5.

This version 3.5 is the result of a lot of training and testing. I take pride in saying that this is the definitive version in the SD 1.5 model. It's worth mentioning that despite using a proprietary training model as a base, this version incorporates other trained models. Therefore, it classifies as a Merge rather than a Fully Trained model.

In this version, a revolutionary training system called DPO - Diffusion-DPO has been included. It is adapted from the recently developed Direct Preference Optimization (DPO), a simpler alternative to RLHF that directly optimizes a policy based on human preferences under a classification objective.

What does it do? The trained DPO models have been observed to produce higher quality images than their untuned counterparts, with a significant emphasis on the model's adherence to your prompt. This model can bring a better prompt adherence than other fine-tuned Stable Diffusion models.

In addition to the innovative DPO system, this version also features:
