The current FLUX models explained
FLUX 3 Action
Specialist model · Sep 23, 2026
FLUX 3 Action is a 7-billion-parameter world action model for robotics. It takes camera frames, a state vector, and a text instruction. It then returns 32 actions and optionally 32 predicted video frames. Image and action tokens are denoised together. The open weights can be adapted to different robot systems.
FLUX.3 Video
Video model · Aug 4, 2026
FLUX.3 Video is Black Forest Labs’ generally available model for text and image inputs. It generates up to 20 seconds with native audio, supports keyframes, and outputs 720p natively; higher resolutions come through upscaling.
FLUX.2 Klein 9B
Image model · January 2026
FLUX.2 Klein 9B combines BFL’s open weights with output up to 4 megapixels, four reference images, and documented API and local use. BFL positions the checkpoint for real-time and high-volume generation.
FLUX.2 Max
Image model · December 2025
FLUX.2 Max is positioned by Black Forest Labs for final image assets at up to 4 megapixels, with up to eight reference images through the API or ten in the Playground. Web search can add grounding.
FLUX.2 Flex
Image model · November 2025
FLUX.2 Flex lets you trade latency, detail, and prompt adherence through the adjustable steps and guidance Black Forest Labs documents. Its focus on typography, text rendering, and small details targets infographics, UI mockups, and visuals with precise labels.
FLUX.2 Pro
Image model · November 2025
FLUX.2 Pro supports up to eight reference images through the API, ten in the playground, and 4-megapixel output. Black Forest Labs also documents photorealistic detail, complex typography, and multi-part prompts.
FLUX 3 Image
Image model · n/a
What is distinctive about FLUX 3 Image is native 2K and 4K output plus references and bounding boxes for arranging objects. Black Forest Labs therefore targets controlled image generation and editing where positions and relationships in the layout matter.
