Official FLUX.2 [dev] (32B) NVFP4 files from BFL: flux2-dev-nvfp4.safetensors and flux2-dev-nvfp4-mixed.safetensors (a few weights kept in BF16). Full BF16 in black-forest-labs/FLUX.2-dev. Gated, FLUX [dev] Non-Commercial License.

FLUX.2 [dev] is Black Forest Labs' 32-billion-parameter rectified flow transformer for generating, editing and combining images from text instructions. The black-forest-labs/FLUX.2-dev-NVFP4 repository holds two official reduced-precision versions: flux2-dev-nvfp4.safetensors (NVFP4) and flux2-dev-nvfp4-mixed.safetensors, which keeps a small set of weights in BF16. The full BF16 weights are in black-forest-labs/FLUX.2-dev. The card states no hardware requirement, settings or quality comparison between the two files. NVFP4 is NVIDIA's 4-bit floating-point format, so check that your GPU and runtime support it before choosing these files over BF16 or FP8 builds. Access and licence: the repository is gated; users accept the FLUX [dev] Non-Commercial License Agreement and acknowledge BFL's Acceptable Use Policy. Based on the black-forest-labs/FLUX.2-dev-NVFP4 card pinned to revision 142b87e70bc3006937b7093d89ff287b5f59f071 and observed on 2026-10-27. Nothing was run here; the card names no supported GPUs, runtimes or quality figures, and the hardware caution is a curator note. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
