This LoRA should enable first-pass generation at high resolution in tall aspect ratios with any model based on SDXL architeture. I've had 100% success with 832x1664 and 95% with 896x1792. Haven't extensively tested the other resolutions. Be warned, it's not really good at landscape generations. Also, the dataset is heavily NSFW 30+ yo based, so while it can do SFW, it will not be good at creating "young cuties", and I consider that inability to actually be an advantage.
