What is Flux 3
Flux 3 is Black Forest Labs' multimodal AI model that generates video up to 20 seconds long in 720p or 1080p, with synchronized audio, from text or images. Released in July 2026, it uses a unified architecture trained on images, video, and audio to produce natural, dynamic clips with multilingual dialogue and scene transitions.
Using it anonymously on Venice
On Venice, Flux 3 runs with anonymized privacy — your prompts are never stored or profiled. This means you get full access to a frontier video model without surveillance, ideal for creators who value sovereignty over their ideas. Venice’s zero-retention policy ensures your concepts stay private, even as you generate high-fidelity, audio-rich video.

Assessment
Strengths and limitations
- Generates up to 20-second video clips: longer than most competing models on Venice.
- Native audio generation with multilingual dialogue and lip-syncing, fully synchronized to video.
- Unified multimodal architecture trained on images, video, and audio for more coherent, physically plausible motion.
- Supports image-to-video animation via the flux-3-image-to-video variant.
- Available on Venice with zero prompt retention, ensuring privacy and IP protection.
- No open weights: cannot be self-hosted or fine-tuned.
- No support for reference images, documents, or video continuation in current Venice implementation.
- Censored output: does not qualify as uncensored on Venice, limiting creative freedom in sensitive domains.
Use cases
What it is good for
- 01Creating short-form branded video content with natural dialogue and lip-sync.
- 02Animating concept art or product mockups into motion for pitches or previews.
- 03Generating social media clips in multiple aspect ratios and resolutions.
- 04Producing multilingual video content without voice actors or dubbing.
- 05Prototyping film scenes or ad concepts with dynamic camera movement and sound.
Prompting
Getting better results
Use clear scene transitions (e.g., 'cut to', 'zoom in') to guide camera movement.
Include dialogue in quotes and specify language (e.g., 'character says: "Hola" in Spanish') for accurate lip-sync.
Specify aspect ratio in the prompt (e.g., '16:9', '9:16') to match platform needs.
For image-to-video, start with a high-contrast, well-lit still to maximize motion clarity.
Use strong action verbs (e.g., 'explodes', 'glides', 'shatters') to trigger dynamic physics.
Avoid overly complex prompts — focus on one scene or action per 20-second clip.
Samples
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera
Alternatives
How it compares
| Model | Best for | Max duration | Max resolution | Native audio |
|---|---|---|---|---|
| Flux 3 | Longer clips with native audio | 20s | 1080p | Yes |
| Grok Imagine 1.5 | Fast ideation | 15s | 1080p | Yes |
| Wan 2.7 Enhanced | Open weights, research use | 15s | 1080p | Yes |
| Kling O3 Pro | Cinematic quality | 15s | — | Yes |
Flux 3 is the right pick on Venice when you need 20-second clips with native, synchronized audio — unmatched for storytelling, dialogue scenes, or social content requiring longer motion.

FAQ
Frequently asked questions
Flux 3 is Black Forest Labs' multimodal AI model that generates video up to 20 seconds long with native audio, from text or images. It uses a unified architecture trained on images, video, and audio for realistic motion and sound, and is available on Venice with privacy-preserving processing.
On Venice, Flux 3 starts at $0.94 per clip for 720p at 5 seconds, with pricing scaling based on resolution and duration. You pay per generation — no subscription required.
No. Flux 3 is a proprietary model from Black Forest Labs and is not open source. You cannot self-host or fine-tune it. Free trials may be available through Venice, but commercial use requires per-clip payment.
Yes. The variant flux-3-image-to-video allows you to animate a still image into a 5–20 second video with motion and sound. It’s available alongside the text-to-video version on Venice.
Flux 3 supports 720p and 1080p resolutions, with aspect ratios including 16:9, 9:16, and others. Output is native — no upscaling required.
Yes. Flux 3 generates native audio synchronized to the video, including multilingual dialogue with accurate lip-syncing. This is built into both text-to-video and image-to-video variants.
Flux 3 wins on clip length (20s vs 15s) and multimodal coherence, while Grok Imagine 1.5 is faster for quick ideation. If you need longer, audio-rich storytelling, Flux 3 is superior. For rapid prototyping, Grok is competitive.
