Method

Couple the randomness. Let the prompt change the drift.

Instead of adding an auxiliary network or optimizing at test time, sync-SDE synchronizes the stochastic fluctuations of source and target reverse processes. The target prompt then changes the drift while the shared noise path keeps the sample close to the source.

01

Invert the source

Evolve the source image through a forward SDE to obtain a structured noisy state and the associated Brownian increments.

02

Reverse the path

Construct the backward Brownian path implied by time reversal and the source prompt score.

03

Sample with target text

Drive the target reverse SDE with that same path, changing only the semantic drift induced by the target prompt.
