About the model

FLUX.2 [klein] trades a little fidelity for a lot of speed. Use it to explore ideas quickly, generate thumbnails and previews, or run large batches where cost per image matters more than the last few percent of detail.

Swap it anytime

Every model takes the same request, so moving to another one means changing the model ID and nothing else.
