PixelMoE applies LLM-style Mixture-of-Experts to pixel-space diffusion models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced PixelMoE, a novel pixel-space diffusion model that leverages LLM-style Mixture-of-Experts (MoE) for efficient scaling. Unlike traditional dense models, PixelMoE uses sparse computation with fine-grained experts and a shared expert for common representations. This approach, combined with Pixel-Space Hierarchical Flow Matching, allows for input-adaptive sparse computation and improved performance across different model scales. PixelMoE achieves competitive FID scores on ImageNet-1K, outperforming dense pixel-space and latent-space generative models at comparable active parameter counts. AI

IMPACT Introduces a novel method for scaling pixel-space diffusion models, potentially improving efficiency and performance in image generation.

    PixelMoE: Scaling Pixel-Space Diffusion with LLM-Style Mixture-of-Experts

    arXiv:2610.18857v2 Announce Type: replace Abstract: Pixel-space diffusion models provide an appealing alternative to latent-space diffusion models by directly modeling raw images without relying on a learned tokenizer. However, scaling pixel-space models has predominantly followe…
