For the z-image model, the best face similarity was achieved around epoch 16 and 17 (3,200 steps and 3,400 steps). For the qwen image 2512 model, the best face similarity was achieved at epoch 20 (4,000 steps). For wan 2.2 low noise, the best face similarity was achieved at epoch 10 (2,000) steps.The attached training data zip includes: the diffusion pipe config files; the training images, prompts, and masks; the validation images (subset of training images); and - for the z-image model - the output of <a target="_blank" rel="ugc" href="https://civarchive.com/articles/26241/stop-training-on-vibes-a-visual-guide-to-biometric-lora-diagnosis-mirror-metrics">MirrorMetrics</a> evaluation of epoch16 and 17 vs. the validation set.z-image model evaluation:<ul><li>For average distances, lower is better.
