MIT creates method to force AI to comply with safety rules
MIT researchers published HardFlow, a method enforcing hard safety constraints on flow-matching generative models' final outputs without retraining.
MIT researchers led by Zeyang Li and Navid Azizan developed HardFlow, a trajectory-optimization method that enforces strict, non-negotiable constraints on flow-matching generative models by checking rule satisfaction only at the final generation step. Published in IEEE TPAMI, it outperformed six rival projection and guidance methods on four simulated benchmarks including D3IL robotic manipulation, Maze2D, physical process control, and image editing. All results are simulation-only, with no independent reproduction yet reported.
- Checks constraints only at final output step, preserving model exploration freedom
- Applies to already-trained models without retraining
- Met constraints every time across D3IL, Maze2D, PDE control, and image editing tasks
- All evaluations were simulations; no real-hardware or production testing reported

5 min read at theframenews.orgSome AI systems build their output gradually, step by step — planning how a robot arm should move, or editing an image — but nothing in how they are built guarantees the finished result follows a strict, non-negotiable rule.
