SDXL Lightning — AI image generator

The fastest model here — a render in about eight seconds.

SDXL Lightning is a step-distilled SDXL that trades sampling steps for latency. It is the quickest turnaround on comfyarts and costs the same 26 credits as the base model, while still accepting LoRAs.

It suits work where throughput is the point: generating many variants to pick from, testing how a LoRA behaves across a range of prompts, or filling a grid of options quickly.

What SDXL Lightning is good for

Worth knowing before you spend credits

Fewer steps means less detail and weaker adherence than base SDXL. It is a drafting tool, not a finishing one.
