Categorical Flow Maps: Fast Discrete Diffusion for Single-Step Generation

Great work by @FEijkelboom et al Floor Eijkelboom (@FEijkelboom) Discrete diffusion — but fast? ⚡️ Test-time inference — but for discrete data? 🧠 Categorical Flow Maps: continuous transport toward the simplex, turning discrete generation into a single-step problem. Built on Variational FM (CatFlow), we obtain (self-)distillation from scratch. Language, molecules, and test-time steering — one framework. Scaling to LLMs and foundation models next.
