Aside from the official code release, I am thrilled to share that Spectral Progressive Diffusion a.k.a. SPEED (arxiv.org/abs/2605.18736) is now integrated into @lmsysorg's SGLang (@sgl_project)! 🚀 Instead of always running diffusion at full resolution, SPEED progressively grows

Today we release the code and a demo for our recent Spectral Progressive Diffusion paper🎉 Play around with it anytime! Just as what we have been doing also, we hope that it encourages the integration of our plug-and-play framework into latest and greatest image and video

Excited to release the code and model weights for our recent paper "Foveated Diffusion: Efficient Spatially Adaptive Image and Video Generation"! We hope this inspires continued research on mixed-resolution diffusion and efficient token allocation for image and video generation.

I integrated our recent work, Spectral Progressive Diffusion a.k.a. SPEED (arxiv.org/abs/2605.18736), with the open-source @ideogram_ai model released yesterday. Turns out our method works out of the box and speeds up inference by up to 1.6× while preserving the high image

Very cool model by @reve. The details and edibility are mind-blowing! From the researchers' posts, I can gather the following: 1. Pixel-space diffusion: they explicitly said "no latent auto-encoders". This is the main reason behind their text rendering quality and

Today, we’re launching Reve 2.0, the best 4K image model in the world. We invented a new way to generate and edit any image using precise layouts. For the first time, it’s possible to create images you can touch.

Active vision has strong implications for robust and efficient autonomous systems. There is a lot of research in VLMs on guiding models to know where to look, and Policy-based Foveated Imaging is the physical realization of exactly that! Super cool work by @howard_xhc!

The era of ultra-high-resolution imaging has arrived. Modern image sensors exceeding 200 MP resolution are common in smartphones, with over 400 MP sensors under development. However, the large number of pixels poses significant challenges for acquisition and processing,
