Trained on Juggernaut X with 100 photos of Natalie Portman in 2004 with GPT-4 captions. Tested on FLUX 1.dev (full) and FLUX fp8 and FLUX nf4 ! Use around strength 0.8-1.2. Distilled CFG 3.5 and CFG 1.0 (without negative prompt). Clipskip 1. Can be used for example as follows:

Positive : {Artstyle, Character and scene description in usual FLUX fashion}, <lora:Natalie_Portman_2004_FLUX_epoch_16:1.1>

v6.0 2004:

Positive : {Artstyle}, {Character and scene description}, elxolsn, <lora:natportman_2003_juggerX_xl_1_wocap-natxprtmn-000149:1.0>

Negative : ugly, deformed, airbrushed, photoshop, rendered, (multiple people), child

Negative : ugly, deformed, airbrushed, photoshop, rendered, (multiple people), child

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.

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.

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.

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.

v1.0:

LoRa trained on 45 images of Natalie Portman with SDXL 1.0 base, The recommended strength for ComfyUi is 1.1.
