It generates clips up to 20 seconds with synchronized audio, at HD and Full HD. The distinguishing property is that one set of weights handles images, video, and audio together rather than stitching separate models into a pipeline. Audio is produced with the picture, so dialogue lands in sync and lip movement matches without a separate dubbing pass. Multilingual dialogue is supported across a broad language set with lip-sync. Generation modes cover text-to-video, image-to-video from a starting frame or visual reference, video-to-video from a reference clip, generative continuation of existing footage, and keyframe-to-video for controlled transitions between defined points. Clips can be chained agentically into longer multi-shot sequences, which is how you get past the 20 second ceiling. Generate video with `generateVideo` from the AI SDK. ## [Copy link to heading](#what-to-consider-when-choosing-a-provider)What To Consider When Choosing a Provider - Configuration: Preference results published at launch are company-run. Black Forest Labs reports Flux 3 winning most head-to-head comparisons against other video models, but the margins narrow considerably against the strongest of them, and sample sizes, rater counts, and methodology were not published. Generate your own comparisons before committing a production pipeline. - Configuration: Output tops out at Full HD. If your pipeline needs 4K natively, this is not the model for it. - Configuration: Video generation is slower and costlier per output than image generation, and iterating on a 20 second clip compounds both. Prototype at shorter durations and lower resolution, then generate the final at full length. See the pricing panel on this page for current rates. - Zero Data Retention: Zero Data Retention is offered on a per-provider and model basis. See the [documentation](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) for details. - Authentication: AI Gateway authenticates requests using an [API key](https://vercel.com/docs/ai-gateway/authentication-and-byok#api-key-authentication) or [OIDC token](https://vercel.com/docs/ai-gateway/authentication-and-byok#oidc-token-authentication). You do not need to manage provider credentials directly. ## [Copy link to heading](#when-to-use-flux-3)When to Use Flux 3 ### Best for - Dialogue-Driven Clips: Audio generated with the picture, lip-sync intact - Multi-Shot Sequences: Agentic chaining past the single-clip ceiling - Keyframe Transitions: Controlled movement between defined points - Reference-Guided Video: Continuation from a frame or a reference clip - Multilingual Output: Lip-sync across a broad language set ### Consider alternatives when - Native 4K Output: Resolution tops out at Full HD - Single Clips Past 20 Seconds: Longer runs require agentic chaining - Independently Verified Quality: Launch comparisons are company-run - Still Image Generation: The FLUX image models are the right family ## [Copy link to heading](#conclusion)Conclusion Flux 3 is Black Forest Labs's first video model, generating up to 20 seconds with audio produced alongside the picture rather than added later. Call `bfl/flux-3-video` through `generateVideo` in the AI SDK, and chain clips agentically when you need a sequence longer than a single generation.
