FLUX 3 Max AI is an independent web workspace at flux3max.com that provides access to the FLUX 3 Max video model alongside FLUX 3, H3 Max and H3 Max Turbo. FLUX 3 Max is described as a video model post-trained by fal Research in partnership with Black Forest Labs, starting from Black Forest Labs' FLUX 3, and released in October 2026; the site states it is not affiliated with or endorsed by either company. The workspace turns a text prompt or a start image into a 5–20 second clip with synced audio at 720p or 1080p.
Key Features
- Two input modes: text to video, and image to video, which requires a start frame (JPG, PNG or WebP) and accepts an optional end frame.
- Audio is generated in the same run as the picture — spoken lines, narration, background ambience and music — with an "Include audio" toggle that is checked by default.
- Duration is set on a slider from 5 to 20 seconds in one-second steps; resolution is selectable at 720p or 1080p.
- Text to video offers aspect ratios from 9:16 vertical to 21:9 widescreen (Auto gives 16:9); image to video keeps the shape of the first frame.
- An Agent mode in the AI Studio can write the prompt, run it, and produce a first frame using GPT Image 2.5 Flare or Nano Banana 2.1.
- Finished takes are saved to your assets, where they can be rewatched and downloaded.
