That’s what is known as multimodality: one model learning several types of information together instead of separate tools bolted side by side.
The video side is the headline feature. FLUX 3 produces clips up to 20 seconds long, with audio generated alongside the picture and synced to what’s happening on screen—dialogue, sound effects, ambient noise. In early evaluations, human reviewers preferred FLUX 3’s output over Runway Gen-4.5 in 77% of head-to-head comparisons and over Luma Ray 3.2 in 93%. It seems to be slightly better than Gemini Omni and Seedance, beating those models in 52% of the evaluations.
Of course, that’s a preference test, not a fixed scoring rubric: evaluators simply watch two clips and pick the one that looks and sounds more convincing, and BFL counts how often FLUX 3 wins.
Other than that, the model seems to be very competent on still images too, following its legacy. BFL shared a few images, and FLUX 3 seems to be very versatile and capable of generating a broad variety of styles beyond photorealism.
“Audi represents the kind of manufacturing partner we built FLUX-mimic for,” said mimic co-founder Stephan-Daniel Gravert. Audi’s Christoph Schneider said the robots now “solve complex soft-body manipulation work” that older machines couldn’t touch. BFL says the full system reacts in about 101 milliseconds, in the neighborhood of human visual reflexes.
The open-source Flux Dev and Schnell models grabbed the “best open source image generator” title that AI artists had expected Stable Diffusion 3.5, Stability’s do-over, to eventually reclaim.
FLUX 3 is BFL’s comeback, and it isn’t fully open yet. Video and Action are in early access now through APIs and select partners, mimic robotics among them, with image generation following “in the coming weeks,” per BFL. The open-weight Dev version, the only tier BFL plans to release for local use, isn’t due until later in 2026.
