alec_helbling · x · 2026-09-08

Diffusion Explorer is an open-source interactive educational tool (1.2k GitHub stars) for visualizing the geometric intuition behind diffusion and flow-based generative models. It implements training objectives like Flow Matching and Denoising Score Matching, shows sample dynamics over time and across training, supports training on custom hand-drawn distributions, and includes an interactive Rectified Flow explainer.
