VESFlow accepted at NeurIPS 2026: training-free velocity editing makes few-step flow matching safe

VESFlow, a training-free safety method for flow matching models, has been accepted to NeurIPS 2026. Existing safety approaches fail in the few-step regime: trajectory-level guidance needs many steps to accumulate small corrections, while embedding-level editing is ineffective because toxic concepts spread across sentence-level embeddings like T5. VESFlow instead edits the velocity field itself, improving generation safety even with only a few sampling steps.
