Changing Your Mind at Step Forty

Exactly what the unswapped run would have produced. The prompt is encoded before sampling begins and its effect is fixed into the starting noise, so replacing the vectors part-way through has nothing left to act on.

A red car on a beach still, with the last ten steps able to shift little beyond colour and surface texture, because the subject and the layout were settled long before the swap.

A blue bicycle in a snowy forest. The final steps are the ones that actually produce the visible image, so whichever prompt is in force at the end is the one that decides what the picture shows.

A mixture in the ratio 40 to 10 — mostly the beach scene, but carrying recognisable bicycle parts and patches of snow, since all fifty steps contribute an equal share of the content.
