Resolution and micro-detail
Ultra belongs at the finishing end when fabric weave, surface texture, foliage, and small product detail survive the final crop. Pro is often sufficient for ideation and standard web delivery.
FLUX 1.1 Pro and Pro Ultra are established Black Forest Labs endpoints with different production profiles. Pro is a strong default for prompt-led still generation. Ultra extends the quality ceiling and supports workflows where high resolution and photographic nuance justify the additional generation cost.
