What is FLUX 3?
FLUX 3 is a multimodal foundation model from Black Forest Labs — the team behind the FLUX.1 and FLUX.2 series. It jointly learns from images, video, and audio within a single unified architecture, so every capability (image synthesis and editing, video with native audio, multilingual text, even action prediction) is built from the same underlying multimodal flow matching backbone.
For creators, that means one model can handle a wide range of tasks that used to require several separate tools — generating images, producing short videos with sound, editing visuals in context, and keeping characters or products consistent across frames.
- Unified multimodal model: image, video, audio, and action in one backbone.
- Image synthesis and editing across many styles, aspect ratios, and resolutions.
- Video generation up to 20 seconds with native audio in a single pass.
- Strong, high-accuracy multilingual text rendering inside images and video.
- In-context editing and multi-image reference for consistency.
- Action prediction for physical AI, developed with mimic robotics.
Capabilities
Four Capabilities, One Model
FLUX 3 covers image, video, audio, and action from a single unified backbone.
Image
Synthesize and edit images across many styles, aspect ratios, and resolutions, with high-accuracy multilingual text and strong prompt-following.
Video
Generate videos up to 20 seconds long with native audio in a single pass — text-to-video, image-to-video, video-to-video, and keyframe-to-video.
Audio
Audio is generated jointly with video, natively — sound is tied to the events on screen, including dialogue, ambience, and sound effects.
Action
FLUX 3 can predict physical actions for robotics, developed with mimic robotics and tested on real production tasks.
Architecture
Built on Self-Flow: One Model, Every Modality
FLUX 3 is a multimodal flow matching model. Rather than bolting a text-to-image model, a video model, and an audio model onto each other, Black Forest Labs trains a single backbone across video, images, and audio at the same time, using an approach they call Self-Flow.
Self-Flow is designed to efficiently align multimodal generation and understanding within the same architecture. According to Black Forest Labs, it achieves lower generation error and higher success rates on manipulation tasks than standard flow matching — which is why FLUX 3 can move so fluidly between generating, editing, and understanding across modalities.
- Single multimodal flow matching backbone shared across all modalities.
- Self-Flow aligns generation and understanding in one architecture.
- Reported lower generation error and higher manipulation success vs standard flow matching.
- Trained by scaling up compute and data across video, images, and audio jointly.

Where FLUX 3 Excels Across Modalities
From image synthesis to 20-second video with native audio, in-context editing, and action prediction.
Image Generation & Editing
FLUX 3 synthesizes and edits images across a wide variety of styles, aspect ratios, and resolutions. Compared with earlier versions of FLUX, it shows a significant improvement in handling complex prompts and in text generation — including high-accuracy text in multiple languages.
- Multiple styles, aspect ratios, and resolutions.
- Marked improvement in complex prompt handling over earlier FLUX.
- High-accuracy multilingual in-image text.
- In-context editing: swap backgrounds, extend canvas, repaint details.
Video Generation up to 20 Seconds — with Native Audio
FLUX 3 generates highly diverse videos up to 20 seconds long in a single generation, and every output includes native audio — sound that corresponds to what's happening on screen.
- Text-to-video, image-to-video, video-to-video, keyframe-to-video, continuation.
- Wide style and aspect-ratio diversity.
- Multilingual dialogue support and strong typography in video.
- Clip chaining into multi-shot, minutes-long sequences.
Native Audio and Multilingual Understanding
Because FLUX 3 is jointly trained on audio and video, sound is generated natively alongside the picture rather than dubbed on after the fact. That includes dialogue, ambience, and sound effects tied to physical events on screen.
- Native joint audio-video generation.
- Dialogue, ambience, and event-tied sound effects.
- Multilingual dialogue in video.
- High-accuracy multilingual text inside images and video.
In-Context Editing & Consistent References
FLUX 3 supports in-context editing across images and video — change backgrounds, extend a canvas, or repaint details while keeping the main subject intact. Multiple reference images keep characters, products, or style consistent across shots.
- Background swaps, canvas extension, detail repaints.
- Multi-image reference for character and product consistency.
- Essential for storytelling and multi-scene workflows.
Beyond Media: Action Prediction for Physical AI
FLUX 3 isn't only a media model. Because it learns a unified representation of the world, it can also predict physical actions — a capability aimed at robotics. Together with mimic robotics, Black Forest Labs developed FLUX-mimic for dexterous manipulation, tested on real production tasks at Audi.
- Native action prediction integrated into FLUX 3.
- Specialized action models fine-tuned from the video backbone.
- FLUX-mimic for dexterous manipulation with mimic robotics.

Prompt library
FLUX 3 Prompt Examples
General-purpose prompts covering cinematic video, multilingual typography, editing, multi-reference consistency, and native audio scenes.
Starting from the provided image, animate a gentle 10-second loop: soft hair movement, blinking eyes, shifting light from a window, and quiet room ambience with faint bird sounds outside.
A bold poster with the word "HELLO" in large serif type beside its equivalents in Chinese (你好), Japanese (こんにちは), and Arabic (مرحبا), vivid gradient background, high-accuracy multilingual text rendering, clean modern layout.
Keep the central character and motion of the source video, but transport the scene to a rainy neon city at night — reflect puddles, glowing signs, soft rainfall sound, and a lo-fi synth soundtrack.
Keep the subject exactly the same. Replace the background with a minimalist studio with a single soft light source, and extend the canvas to a 16:9 banner on the left side with clean negative space.
Using the uploaded reference images to keep the same character, generate a 15-second video of that character walking through three different locations — a forest, a subway station, and a beach — with consistent face, clothing, and proportions across all shots.
A 12-second video of a woodworker carving a chair in a workshop — include the rhythmic sound of the chisel, wood creaks, soft workshop ambience, and a faint radio playing in the background, all tied to the on-screen actions.
A whimsical Studio-Ghibli-style illustration of a floating market on clouds, warm watercolor textures, soft pastel palette, vendors on small boats, drifting lanterns, gentle depth of field.
