v1.0: LoRa trained on 45 images of Natalie Portman with SDXL 1.0 base, The recommended strength for ComfyUi is 1.1.v2.0:Lora trained on 270 images of Natalie Portman with SDXL 1.0 base. The lora is also tested on Juggernaut XL 3.0. Most of the sample images were created with Juggernaut other than the "...2004..." generated ones.v3.0: Retrained on 200 images but with an improved Lora training method and model to yield higher flexibility while preserving likeness and GPT-4 Vision captioning. Keep weight at 1.05-1.1.v3.1: Trained on a subset of the 200 images dataset from v3.0 but that is better balanced and has better captioning (more refined GPT-4 Vision prompt). Lora strength between 0.8-1.2.v4.0 80mb : Trained on 137 photos of Natalie Portman with an improved Lora model which has a much reduced size while maintaining likeness. Put the keyword : "natxportman" at the beginning of prompts! Use Lora with strength around 1.1.
