MIT unveils HardFlow: plug-and-play hard constraints for generative models
MIT News on September 14, 2026 describes HardFlow, an algorithm from MIT researchers that plugs in at deployment for pretrained generative models and enforces hard constraints on the final output only—not every intermediate step. They report perfect constraint satisfaction in robotics manipulation, maze navigation, and text-guided image editing, with better solution quality than baselines and faster collision-free robot paths.
