FLUX 3 Max is a fast text-to-video model for creators and advertisers who need short, sound-bearing clips in seconds rather than minutes. Released October 19, 2026 by fal Research with Black Forest Labs, it generates 5 to 20 second clips with native audio from a prompt, a start image, or up to ten keyframes.
Core Features
- Built on Black Forest Labs' FLUX 3 foundation and post-trained by fal for closer prompt adherence and higher Elo.
- Native audio generated in the same pass, with ambience, effects, and quoted dialogue lip-synced to the speaker.
- Lengths from 5 to 20 seconds at 720p by default or 1080p, with seven text-to-video aspect ratios.
- Image-to-video and keyframe control, including an optional end frame.
- Vendor-reported about 22x faster than Seedance 2.5 at equal quality, a 10s clip in roughly 12 seconds.
Use Cases and Best For
- Ad agencies producing many storyboard variants quickly.
- Social teams making lip-synced short videos with spoken lines.
- Filmmakers previewing shots before committing to longer renders.
Pricing
Available through fal and Morphic on credit-based plans; a 5-second 720p clip costs 51 credits and a 20-second 1080p clip 348 credits on fal. Morphic offers free and paid tiers from $19 per month with a 75 percent launch discount through November 7.
Our Take
Best for speed-first short video with synchronized sound; the trade-off is a roughly 20-second clip ceiling and vendor-only latency claims.
