Only exact, source-certified variants attached to this release are shown.
Recommended hardware
Use only the listed runtime configurations with the exact checkpoint precision. Hardware sizing considers resident pipeline memory, runtime overhead, input and output dimensions, batch size, and safety headroom.
Non-Commercial Only
The public checkpoint is technically self-hostable, but its license prohibits commercial or production use. No commercial hosting offer is shown.
License and self-hosting considerations
The exact pipeline and selected precision must fit on the chosen GPUs. Requirements vary with resolution, duration, batch size, modalities, and runtime; language-model KV-cache rules are not applied.
FLUX.2-dev is published under FLUX Non-Commercial License v2.0. The release-scoped official license link and verification date are retained with the catalogue record.
