Our take
Massive bootstrap or prompt sweep: schnell. Test set where base realism matters: dev. Either way, the deterministic stage multiplies for free.
Two open FLUX models, two philosophies: schnell optimizes throughput and cost, dev optimizes quality. The right choice depends on whether you bootstrap in volume or aim for clean bases.
