Is there a standard, user-friendly way of generating consistent AI images yet? Or is it just starting to emerge in patches like the tool here? Because DALL-E for example is a complete crapshoot; it has no ability for fine-tuning or persistence across images/iterations.
They used LoRa. Alternatively you can use IP-Adapter and ControlNet, there are models for face, style, composition, lighting, etc... Search for "ComfyUI IP-Adapter workflow".
