FLUX 3 — Multimodal AI Image and Video Generator

FLUX 3 is Black Forest Labs' first multimodal foundation model, trained jointly on images, video, and audio through Self-Flow, a unified architecture that aligns generation and understanding across all three modalities simultaneously. It generates images, video clips up to 20 seconds with native synchronized audio, multilingual dialogue, animated typography, and multi-shot sequences from text or reference inputs.

Self-Flow is Black Forest Labs' architecture for efficiently aligning multimodal generation and understanding within the same model. Because images, video, and audio are each a different projection of the same underlying reality, training across all three simultaneously gives each modality constraints from the others: sound has to match the impact, motion has to obey the mass, and the future has to follow from the past. This produces a model that understands the world rather than learning three separate tasks. Read more about related models on ImagineArt's AI video generatorAI video generator hub.

FLUX 3 supports six modes: text-to-video, image-to-video from a starting frame or visual reference, video-to-video carrying characters or elements from a source clip into a new scene, keyframe-to-video for controlled transitions between defined moments, generative video-audio continuation from input video and audio, and multilingual dialogue generation with accurate lip-sync. For comparison, Gemini Omni FlashGemini Omni Flash supports conversational multi-turn video editing and Seedance 2.0Seedance 2.0 supports up to 12 simultaneous multimodal reference inputs.

Yes. Native synchronized audio is generated alongside the video in a single pass. The audio reflects the physical events, environment, and causal context of the scene rather than applying a generic background track. Multilingual dialogue with accurate lip-sync is also generated natively without external dubbing or post-production.

FLUX 3 generates individual clips up to 20 seconds in a single pass. Agentic clip chaining extends output into sequences lasting several minutes by connecting individual clips with visual references keeping characters and style consistent across every cut. For native single-pass generation up to 30 seconds, see Seedance 2.5Seedance 2.5 on ImagineArt.

In preliminary evaluations, FLUX 3 was preferred over Runway Gen-4.5 in 77% of comparisons, Luma Ray 3.2 in 93%, Grok Imagine Video in 69%, Kling v3 Pro in 60%, Happy Horse v1 in 59%, Happy Horse 1.1 in 57%, and Seedance 2.0 and Gemini Omni Flash in 52%. These are early results from Black Forest Labs' own evaluations and further improvements are expected during early access.
