Flux 3 unifies image, video, audio and action in one world model.
Flux 3 is Black Forest Labs’ multimodal foundation model for image, video, native audio and action prediction. Build one coherent scene brief here, then continue to Flux3.co to explore the available workflow.

The architecture changes the brief
The modalities are evidence about the same scene.
Separate generators hand work from one model to another. Flux 3 is trained so appearance, motion and sound constrain each other inside one foundation. The practical goal is not more switches—it is fewer contradictions between the parts of a scene.
Separate generation stack
- A still establishes the look
- A video model rebuilds the motion
- Audio is layered after the picture
- Continuity is repaired between tools
Flux 3 world brief
- References guide one shared scene
- Motion follows objects and materials
- Sound belongs to visible events
- Action is grounded in predicted change
What is being unified
Four capabilities, one creative direction.
Flux 3 is broader than an image upgrade. Each capability contributes a different constraint to the same imagined world.
Image synthesis and editing
Create or revise still images across varied styles, aspect ratios and resolutions. Black Forest Labs reports stronger complex-prompt handling and multilingual text than earlier Flux generations.
Video with scene continuity
Generate from text, a starting frame, visual references, an existing clip or defined keyframes. The model is designed to carry central subjects and scene logic through motion.
Native synchronized audio
Dialogue, ambience and sound effects can be produced with the visuals. This connects a sound to the event that causes it instead of treating audio as a detached finishing layer.
Action and physical prediction
The same backbone can support action prediction through specialized systems such as Flux-mimic. For creators, that research explains the emphasis on contact, weight, cause and response.
A practical prompt sequence
Write one world brief in four passes.
Do not compress every idea into a cloud of adjectives. Establish what must stay fixed, then direct what changes over time.
- 01
Anchor the world
Define the subject, environment, time of day, materials and visual style. Name the details that should survive every shot or edit.
- 02
Direct change over time
Describe the action in playback order. Add camera movement separately so subject motion and camera motion are not confused.
- 03
Connect sound to events
Specify dialogue, ambience and only the important effects. Tie each effect to a visible cause and state when music should enter or recede.
- 04
Use references with a job
Explain whether each image or clip controls identity, style, layout, motion or continuity. Remove references that repeat the same instruction without adding information.
Where the unified model matters
Start where picture and sound must agree.
Flux 3 is most distinctive when a deliverable crosses modalities. A dedicated tool may still be the better choice for a single isolated asset.
Film and campaign previsualization
Explore a scene’s composition, motion, dialogue and atmosphere together before committing to a shoot, final animation or full post-production pipeline.
Product stories
Carry a product, material language and brand mood from a hero still into launch clips, demonstrations and sound-aware social concepts.
Character and world development
Use visual references to test recurring characters, locations, camera language and multi-shot sequences without re-describing the world from zero.
Interactive and physical prototyping
Sketch how a world or object might respond to an action. Treat this as exploration; production control and robotics remain separate, specialized workflows.
Prompt anatomy
Give every modality a clear job.
This compact structure keeps the scene legible. Use only the lines your deliverable needs.
A ceramic repair robot works inside a humid greenhouse just after sunrise.
Keep the same robot, chipped glaze, plant layout and warm glass reflections across every shot.
It tightens a copper valve, pauses when steam escapes, then shields a nearby seedling.
Begin wide, glide toward the hands, then hold a close profile as the steam clears.
Use quiet servo clicks, birds beyond the glass and one soft hiss synchronized to the valve.
Before you plan production
Announced capability is not the same as general availability.
Flux 3 launched as an early-access program. Read the current product controls before building a deadline, budget or local deployment plan around it.
The rollout is staged
Flux 3 Video is available through early access. Black Forest Labs says image access, additional APIs, private weights and Flux 3 Dev will follow through separate rollout stages.
Evaluations are preliminary
Published comparisons were run during development and may change as the model and evaluation harness improve. Treat them as early signals, not permanent benchmark conclusions.
Local requirements are unknown
An open-weight multimodal backbone is planned, but final model size, hardware requirements, licensing and practical consumer deployment details are not yet established.
A first cut still needs finishing
Native audio and continuity can reduce assembly work, but exact timing, edits, safety review, rights clearance and final mastering remain production responsibilities.
Practical answers
Frequently asked questions
What is Flux 3?
Flux 3 is Black Forest Labs’ multimodal foundation model trained jointly across images, video and audio, with related work in action prediction. It is designed to model how a scene looks, changes, sounds and responds rather than treating each modality as an isolated task.
Can I generate with Flux 3 on this page?
No. This is an independent editorial guide, not a disguised generator. The main buttons open Flux3.co, where you can review the currently available playground, account requirements, controls and pricing.
What can Flux 3 Video generate?
Official materials describe text-to-video, image-to-video, reference-guided video, video-to-video, video and audio continuation, keyframe transitions, multilingual dialogue and native audio. Individual controls depend on the current early-access surface.
How long can Flux 3 videos be?
Black Forest Labs says Flux 3 can generate video with native audio up to 20 seconds in a single generation. Its published preliminary evaluation used 10-second, 720p text-to-video clips.
Is Flux 3 open source?
Black Forest Labs plans Flux 3 Dev as an open-weight multimodal backbone. That does not automatically mean an open-source license, and the final license, size and hardware requirements should be checked when the weights are released.
Is Flux 3 Image available now?
At the time of writing, Black Forest Labs says Flux 3 Image early access will open in the following weeks. Availability may change quickly, so check the linked playground and official announcement for the current state.
