Fast Iterator HLD

This photorealistic model is a mixed merge of dozens of checkpoints and LORAs from the past couple of years, including quite a few of the latter directly trained by myself. Unfortunately, as I did not plan ahead to release it and I have been adapting it for so long, I have not kept track of everything included in it, so I apologize in advance for not naming individual contributors, and thank instead the whole CIVITAI community.

I developed it for fast response and LORA compatibility, and I often combine in workflows with Z image Turbo, Qwen or more specialized SDXL models. It tends to work well with all sorts of SDXL, Illustrious and PNY LORAs, and outputs are good at 1280x1280 resolution, but still works OK at higher ones.

The first 9 sample images are direct output from the model alone (sometimes with face refiner) without LORAs, but results can be greatly improved with a variety of LORAs and embeddings, as shown in the rest of the showcased images.

Although not created for NSFW stuff, the model’s genes include that capability and it tends to add gratuitous nudity, so be careful when prompting, being specific about clothing, appropriate subject ages, etc. so as to avoid undesirable effects.

OPTIMAL SETTINGS: The model yields rather different results depending on the sampler / cfg / noise shift combination chosen, and output will be terrible if wrongly paired. It is very fast, particularly with LCM or TCD sampling. I recommend:

CLIP Skip: 2

LCM sampler / CFG 0.9-3 / 16+ steps / noise shift 1-1.3 

TCD sampler  CFG 0.9-3 / SSS 30-35% / 16+ steps / noise shift 1.2

Euler A AYS sampler / CFG 0.9-2 / 8-16 steps/ noise shift close to 1.

DPM++ SDE Substep / CFG 0.9-1-2 / 16 steps/ noise shift 0.9-1
