Overview
- Black Forest Labs opened FLUX 3 in Early Access on Thursday, offering text-to-video clips up to 20 seconds with native, synchronized audio plus early action-prediction tools available to partners and via APIs.
- FLUX 3 is built on BFL’s Self-Flow approach that trains a single model on images, video and audio to capture motion, contact and sound so the same backbone can power image synthesis, video+audio generation, and action prediction.
- A specialized variant, FLUX-mimic, was developed with mimic robotics and is being tested by Audi for high-dexterity tasks such as fitting flexible door seals on production lines, with the partners reporting much faster fine-tuning from limited demonstration data.
- BFL published preliminary human-preference evaluations showing FLUX 3 favored over several competitors in early head-to-head tests, but the company describes these results as early and subject to further validation during the access phase.
- The company closed a $300 million Series B that values BFL at $3.25 billion and outlined a phased rollout that will expose Video and Action to partners now, add Image generation in the coming weeks, and release an open-weight developer backbone later in 2026.
