What Time Is It? How Data Geometry Makes Time Conditioning Optional for Flow Matching
arXiv CS.LG

ArXi:2605.08344v1 Announce Type: new Recent work has shown that models flow matching models can be trained without explicit time conditioning, challenging the standard view that the interpolation time is needed to disambiguate velocity targets. But why should a time-blind model work at all? Decomposing the time-blind flow matching loss, we identify two sources of irreducible
