Black Forest Labs (BFL) has released FLUX 3<\/a>, a multimodal foundation model that learns from images, videos and audio inside a single architecture. It is also the first FLUX model to ship video, audio and action prediction from one set of weights.<\/p>\n

The Black Forest Labs (BFL) research team argues that no single modality gives a complete description of the world. Images capture spatial structure at one instant. Video restores time and exposes physical dynamics. Audio reveals causal relationships between mechanical events and sound. Each is treated as a lossy projection of the same underlying reality.<\/p>\n

Training on all of them at once means the modalities constrain each other. The sound has to match the impact. The motion has to obey the mass. The research team calls FLUX 3 its first model built entirely on that principle.<\/p>\n

The method underneath: Self-Flow<\/strong><\/h2>\n

FLUX 3 builds on Self-Flow<\/a>, BFL\u2019s method for aligning multimodal generation and understanding in one architecture. Self-Flow combines the flow matching objective with a self-supervised feature reconstruction objective. The reference implementation on GitHub<\/a> is Apache-2.0 and uses SiT-XL\/2 with per-token timestep conditioning. It trains with a 25% per-token mask ratio and self-distillation from an EMA teacher at layer 20 to a student at layer 8.<\/p>\n

That released checkpoint is an ImageNet 256\u00d7256 research model, not FLUX 3. BFL states that it \u2018significantly scaled up compute and data resources\u2019 on the same approach to train FLUX 3 across video, images and audio simultaneously. Self-Flow itself was introduced in March 2026, so it is not new to this launch. What is new is the scale.<\/p>\n

What FLUX 3 Video does<\/strong><\/h2>\n

FLUX 3 Video generates clips up to 20 seconds long in a single generation, with native audio. The supported modes cover text-to-video, image-to-video, video-to-video from a reference clip, keyframe-to-video for controlled transitions, and generative video-audio continuation from input video and audio.<\/p>\n

BFL also lists multilingual dialogue, agentic chaining of clips into multi-shot sequences, and strong typography generation with animated designs. The BFL team reports particular strength in human facial expressions and in associating sounds with physical events.<\/p>\n

Performance<\/strong><\/h2>\n

BFL team published preliminary human preference results. The setup was 10-second text-to-video clips at 720p with audio. FLUX 3 was preferred over Luma Ray 3.2 in 93% of comparisons and over Runway Gen-4.5 in 77%. Against Grok Imagine Video the figure is up to 69%, then Kling v3 Pro at 60%, Happy Horse v1 at 59% and Happy Horse 1.1 at 57%. Against Seedance 2.0 and Gemini Omni Flash the result is 52%, close to a coin flip.<\/p>\n
