FLUX 3 is Black Forest Labs' first model for unified video-and-audio generation, launched July 23, 2026. Unlike most video tools that bolt on sound afterward, it is trained on images, video, and audio inside one shared architecture, so it generates picture and synchronized audio in the same pass. Black Forest Labs, the lab behind the FLUX.2 image models, built it to remove the manual sound-sync step.
Core Features
- Generates video clips up to 20 seconds long with audio produced alongside the footage, not added in post.
- Accepts text, still images, or existing video as a starting point for image-to-video and video-to-video work.
- A single unified architecture instead of separately trained image, video, and audio specialists.
- A FLUX-mimic offshoot applies the same model to robot-movement prediction, tested on Audi production lines.
Use Cases / Best For
- Video studios and content creators who currently sync dialogue, footsteps, and ambient sound by hand.
- Filmmakers prototyping scenes where picture and sound must stay locked together from the first frame.
- Robotics teams exploring movement prediction from the same foundation model family.
Pros & Cons
- Pro: Picture and audio are generated together, so lip-sync and ambient sound stay locked from frame one.
- Con: It is gated early access with no public pricing yet, so most teams must wait for general release.
Pricing
FLUX 3 is in gated early access via a request at bfl.ai; broad video pricing is not yet public. Black Forest Labs' consumer image tiers (FLUX.2 Pro around $10/mo) hint at the eventual model, and a free downloadable version is planned for later in 2026.
Our Take: Best for production studios that want sound and picture generated together rather than stitched; the trade-off is availability - it is gated, so most users will wait for the public release. Compare it with other tools in our AI Video category.
