Snap Inc. has launched SnapGen++, a compact diffusion transformer that revolutionizes mobile text-to-image generation. This innovative model, boasting 0.4 billion parameters, outperforms competitors up to 30 times larger, generating high-resolution 1024 x 1024 pixel images in just 1.8 seconds on devices like the iPhone 16 Pro Max. Unlike previous models relying on U-Net architectures, SnapGen++ employs a powerful diffusion transformer, which enhances image quality and coherence. A new attention method significantly reduces computational demands, enabling efficient processing while maintaining high fidelity. This model features three variants—Tiny, Small, and Full—adaptable to various devices. Benchmark tests show SnapGen++ consistently surpasses larger models such as Flux and SD3.5-Large in image quality and alignment. As Snap continues to invest in AI for its app, this development marks a significant advancement in mobile AI capabilities. The integration of advanced features promises to enhance user experiences within Snapchat.
