The fastest way to try AI image generation — create 1024px images in seconds, completely free with your welcome credits.
SDXL‑Lightning is the quickest on‑ramp to AI image generation on NeonLights AI. Built by ByteDance using progressive adversarial diffusion distillation, it generates 1024px images in just 4 inference steps — making it near‑instant compared to standard diffusion models.
Every new NeonLights AI account receives 5 free welcome credits, and SDXL‑Lightning costs exactly 5 credits per image. That means you can generate your first AI image the moment you sign up, with zero cost and zero setup. It's the perfect way to explore prompting, test ideas, and see what AI image generation is all about before moving on to our more advanced models.
Key Features
Lightning‑Fast Generation
Only 4 inference steps to produce a complete image. Results arrive in seconds, not minutes — ideal for rapid iteration and prompt experimentation.
Free to Try
At just 5 credits per image, SDXL‑Lightning is covered entirely by the free welcome credits every new account receives. No payment needed.
1024px Output
Generates images at 1024×1024 native resolution with support for 5 aspect ratios including portrait, landscape, and square formats.
Perfect for Experimentation
The low cost and instant speed make it ideal for learning how prompts work, testing composition ideas, and exploring different styles before committing credits to premium models.
5 Aspect Ratios
Choose from 1:1 (square), 16:9 (widescreen), 9:16 (portrait/stories), 4:3 (classic), and 3:4 (portrait) to match your content needs.
How It Works
SDXL‑Lightning is distilled from Stability AI's Stable Diffusion XL Base 1.0 using progressive adversarial diffusion distillation. This technique compresses the standard multi‑step diffusion process into just 4 steps while retaining the core image generation capability.
The result is an extremely fast generation pipeline that can produce a complete 1024px image in a fraction of the time needed by full‑step models.
