cellflow.solvers.OTFlowMatching.cfg_enabled

property OTFlowMatching.cfg_enabled: bool

Whether classifier-free guidance is available at predict time.

Guidance needs a meaningful unconditional velocity v_null, which only exists when the velocity field was trained with condition dropout (condition_dropout_prob > 0). When False, a per-call guidance_scale is ignored (with a warning) and the plain conditional velocity is used.
