Routing Matters in MoE: Scaling Diffusion Transformers with Explicit Routing Guidance

ICLR 2026poster

Mixture-of-Experts (MoE) has emerged as a powerful paradigm for scaling model capacity while preserving computational efficiency. Despite its notable success in large language models (LLMs), existing attempts to apply MoE to Diffusion Transformers (DiTs) have yielded limited gains. We attribute this…

Framer: Interactive Frame Interpolation

ICLR 2025poster

We propose Framer for interactive frame interpolation, which targets producing smoothly transitioning frames between two images as per user creativity. Concretely, besides taking the start and end frames as inputs, our approach supports customizing the transition process by tailoring the trajectory…

Speculative Jacobi-Denoising Decoding for Accelerating Autoregressive Text-to-image Generation

NeurIPS 2025poster

As a new paradigm of visual content generation, autoregressive text-to-image models suffer from slow inference due to their sequential token-by-token decoding process, often requiring thousands of model forward passes to generate a single image. To address this inefficiency, we propose Speculative J…

TTS-VAR: A Test-Time Scaling Framework for Visual Auto-Regressive Generation

NeurIPS 2025poster

Scaling visual generation models is essential for real-world content creation, yet requires substantial training and computational expenses. Alternatively, test-time scaling has garnered growing attention due to resource efficiency and promising performance. In this work, we present the first genera…

Wan-Move: Motion-controllable Video Generation via Latent Trajectory Guidance

NeurIPS 2025poster

We present Wan-Move, a simple and scalable framework that brings motion control to video generative models. Existing motion-controllable methods typically suffer from coarse control granularity and limited scalability, leaving their outputs insufficient for practical use. We narrow this gap by achie…

FreeCompose: Generic Zero-Shot Image Composition with Diffusion Prior

ECCV 2024poster

"[width=0.985]assets/teaser.pdf Figure 1: harnesses the generative prior of pre-trained diffusion models to achieve versatile image composition, such as appearance editing (image harmonization) and semantic editing (semantic image composition). Furthermore, it can be extended to various downstream a…

Image Textualization: An Automatic Framework for Generating Rich and Detailed Image Descriptions

NeurIPS 2024poster

Image description datasets play a crucial role in the advancement of various applications such as image understanding, text-to-image generation, and text-image retrieval. Currently, image description datasets primarily originate from two sources. One source is the scraping of image-text pairs from t…
