What is Flux 2.0?

Released in early 2026, Flux 2.0 from Black Forest Labs is a versatile image family widely used for production pipelines and fine-tuning. APIMart exposes `flux-2-flex` for fast iteration and `flux-2-pro` for sharper detail — both support seven aspect ratios and optional reference images.

Flex vs Pro

Flex optimizes latency; Pro prioritizes texture, edges, and fine detail at 1K/2K.

Image-to-image

Up to 8 reference URLs steer style, composition, or edits (public URLs only).

1K / 2K tiers

Resolution table from 1440×1440 up to 2048×1152 for 16:9 widescreen.

Ecosystem fit

Popular for teams that may later self-host or fine-tune open-weight variants.
