GLASS Flows: Efficient Inference for Reward Alignment of Flow and Diffusion Models

ICLR 2026oral

The performance of flow matching and diffusion models can be greatly improved at inference time using reward adaptation algorithms, yet efficiency remains a major limitation. While several algorithms were proposed, we demonstrate that a common bottleneck is the *sampling* method these algorithms rel…

VideoJAM: Joint Appearance-Motion Representations for Enhanced Motion Generation in Video Models

ICML 2025oral

Despite tremendous recent progress, generative video models still struggle to capture real-world motion, dynamics, and physics. We show that this limitation arises from the conventional pixel reconstruction objective, which biases models toward appearance fidelity at the expense of motion coherence.…

Bespoke Non-Stationary Solvers for Fast Sampling of Diffusion and Flow Models

ICML 2024poster

This paper introduces Bespoke Non-Stationary (BNS) Solvers, a solver distillation approach to improve sample efficiency of Diffusion and Flow models. BNS solvers are based on a family of non-stationary solvers that provably subsumes existing numerical ODE solvers and consequently demonstrate conside…

D-Flow: Differentiating through Flows for Controlled Generation

ICML 2024poster

Taming the generation outcome of state of the art Diffusion and Flow-Matching (FM) models without having to re-train a task-specific model unlocks a powerful tool for solving inverse problems, conditional generation, and controlled generation in general. In this work we introduce *D-Flow*, a simple…

Emu Edit: Precise Image Editing via Recognition and Generation Tasks

CVPR 2024highlight

Instruction-based image editing holds immense potential for a variety of applications as it enables users to perform any editing operation using a natural language instruction. However current models in this domain often struggle with accurately executing user instructions. We present Emu Edit a mul…

AudioGen: Textually Guided Audio Generation

ICLR 2023poster

In this work, we tackle the problem of generating audio samples conditioned on descriptive text captions. We propose AudioGen, an auto-regressive generative model, operating on a learnt discrete audio representation, that generates audio samples conditioned on text inputs. The task of text-to-audio…

Make-A-Video: Text-to-Video Generation without Text-Video Data

ICLR 2023poster

We propose Make-A-Video -- an approach for directly translating the tremendous recent progress in Text-to-Image (T2I) generation to Text-to-Video (T2V). Our intuition is simple: learn what the world looks like and how it is described from paired text-image data, and learn how the world moves from un…

Pick-a-Pic: An Open Dataset of User Preferences for Text-to-Image Generation

NeurIPS 2023poster

The ability to collect a large dataset of human preferences from text-to-image users is usually limited to companies, making such datasets inaccessible to the public. To address this issue, we create a web app that enables text-to-image users to generate images and specify their preferences. Using t…

Text-To-4D Dynamic Scene Generation

ICML 2023poster

We present MAV3D (Make-A-Video3D), a method for generating three-dimensional dynamic scenes from text descriptions. Our approach uses a 4D dynamic Neural Radiance Field (NeRF), which is optimized for scene appearance, density, and motion consistency by querying a Text-to-Video (T2V) diffusion-based…

kNN-Diffusion: Image Generation via Large-Scale Retrieval

ICLR 2023poster

Recent text-to-image models have achieved impressive results. However, since they require large-scale datasets of text-image pairs, it is impractical to train them on new domains where data is scarce or not labeled. In this work, we propose using large-scale retrieval methods, in particular, efficie…
