Presenting the groundbreaking SDXL Lightning checkpoint on OctoAI, revolutionizing the generation of high-quality SDXL images from text in mere seconds, all at the most competitive prices. This latest addition to OctoAI's suite of media generation solutions empowers users to effortlessly produce top-tier SDXL output with just 4-8 simple steps, boasting latency of less than one second. This stands in stark contrast to generating images using SDXL model, which typically demands 30-40 steps to produce a good quality image in 3-3.5 seconds, and even more when incorporating custom assets like LoRAs.

Accessible through OctoAI’s SDXL API, the SDXL Lightning checkpoint seamlessly integrates with SDXL models, effortlessly adapting to style presets and LoRAs, thus enhancing its versatility and practicality.

To fully harness the power of SDXL lightning, adhere to these recommendations:

  • Opt for 4-8 steps, with 8 steps being the recommended choice.

  • Maintain a low CFG Scale, ideally ranging from 1.4 to 4.0, with 3.0 as the optimal value.

  • Utilize any sampler, textual inversion, or style preset.

  • Note that additional LoRAs and VAEs will result in increased inference time.

In this post, we'll provide a walkthrough on leveraging the SDXL lightning functionality within the OctoAI SDXL ImageGen API.

Let’s say you are an e-commerce merchant selling glass orbs for the holiday season. Using OctoAI SDXL with default settings — base style and 30 steps, you can generate the following image within 2.8 seconds:
