Gumbel Straight Flow: Distilling Autoregressive Models into One-step Flow Maps

Yeongmin Kim, Arnaud Doucet, Andrew Campbell +3

We present Gumbel Straight Flow (GSF), a continuous flow map language model that leverages the noise-data coupling of a pretrained autoregressive language (AR) model. We theoretica…

Simplex Diffusion Models

Justin Deschenaux, Alexandre Galashov, Andrew Campbell +4

Diffusion models have revolutionized generative modeling for continuous data through the gradual refinement of a belief state. This iterative refinement has not yet carried over to…

Adversarial Learning of Classifier-Free Guidance Schedules

Ashwini Pokle, Alexandre Galashov, Arnaud Doucet +2

Modern text-to-image diffusion models rely on classifier-free guidance (CFG) to achieve high image fidelity and text alignment. However, CFG typically applies a static, global scal…

DiffusionGemma Technical Report

DiffusionGemma Team, Adrien Ali Taïga, James Assiene +41

We introduce DiffusionGemma, an experimental open-weight language model that uses discrete diffusion to generate text at exceptionally high speed. Rather than decoding one token at…

Diffusion Fine-tuning with Rewarded Moment Matching Distillation

Alexis Jacq, Guillaume Couairon, Valentin De Bortoli +3

Distillation and Reinforcement Learning (RL) fine-tuning are the primary pillars of diffusion post-training. While traditionally studied in isolation, the interaction between these…

Accelerating Speculative Diffusions via Block Verification

Alexander Soen, Hisham Husain, Valentin De Bortoli +1

Speculative decoding speeds up LLM inference by using a draft model to generate tokens, with an acceptance-rejection scheme that ensures that the output matches the target distribu…

On the Wasserstein Gradient Flow Interpretation of Drifting Models

Arthur Gretton, Li Kevin Wenliang, Alexandre Galashov +3

Recently, Deng et al. (2026) proposed Generative Modeling via Drifting (GMD), a novel framework for generative tasks. This note presents an analysis of GMD through the lens of Wass…

Self-Speculative Masked Diffusions

Andrew Campbell, Valentin De Bortoli, Jiaxin Shi +1

We present self-speculative masked diffusions, a new class of masked diffusion generative models for discrete data that require significantly fewer function evaluations to generate…

Learn to Guide Your Diffusion Model

Alexandre Galashov, Ashwini Pokle, Arnaud Doucet +3

Classifier-free guidance (CFG) is a widely used technique for improving the perceptual quality of samples from conditional diffusion models. It operates by linearly combining condi…

Feynman-Kac Correctors in Diffusion: Annealing, Guidance, and Product of Experts

Marta Skreta, Tara Akhound-Sadegh, Viktor Ohanesian +6

While score-based generative models are the model of choice across diverse domains, there are limited tools available for controlling inference-time behavior in a principled manner…

Distributional Diffusion Models with Scoring Rules

Valentin De Bortoli, Alexandre Galashov, J. Swaroop Guntupalli +4

Diffusion models generate high-quality synthetic data. They operate by defining a continuous-time forward process which gradually adds Gaussian noise to data until fully corrupted.…

Accelerated Diffusion Models via Speculative Sampling

Valentin De Bortoli, Alexandre Galashov, Arthur Gretton +1

Speculative sampling is a popular technique for accelerating inference in Large Language Models by generating candidate tokens using a fast draft model and accepting or rejecting t…

Schrödinger Bridge Flow for Unpaired Data Translation

Valentin De Bortoli, Iryna Korshunova, Andriy Mnih +1

Mass transport problems arise in many areas of machine learning whereby one wants to compute a map transporting one distribution to another. Generative modeling techniques like Gen…

Simplified and Generalized Masked Diffusion for Discrete Data

Jiaxin Shi, Kehang Han, Zhe Wang +2

Masked (or absorbing) diffusion is actively explored as an alternative to autoregressive models for generative modeling of discrete data. However, existing work in this area has be…

Target Score Matching

Valentin De Bortoli, Michael Hutchinson, Peter Wirnsberger +1

Denoising Score Matching estimates the score of a noised version of a target distribution by minimizing a regression loss and is widely used to train the popular class of Denoising…

Particle Denoising Diffusion Sampler

Angus Phillips, Hai-Dang Dau, Michael John Hutchinson +3

Denoising diffusion models have become ubiquitous for generative modeling. The core idea is to transport the data distribution to a Gaussian by using a diffusion. Approximate sampl…

Implicit Diffusion: Efficient Optimization through Stochastic Sampling

Pierre Marion, Anna Korba, Peter Bartlett +6

We present a new algorithm to optimize distributions defined implicitly by parameterized stochastic diffusions. Doing so allows us to modify the outcome distribution of sampling pr…
