Flux 3 (flux-ai.video)

Flux 3 is a web interface for Black Forest Labs' Flux 3 model, generating AI video, still images, and native audio from a single prompt. It is built for content creators, marketing teams, filmmakers, and developers who want image, video, and audio produced together and in sync.

Users describe a shot or upload a reference image or keyframe, choose to generate a still image or a video up to 20 seconds with native audio, set the aspect ratio and style, then generate; results can be extended, refined, or downloaded once ready.

Flux 3 generates up to 20 seconds of video with synchronized dialogue, sound effects, and music, alongside photoreal images with accurate multilingual typography. It keeps characters and style consistent across chained clips and supports multilingual dialogue with matching motion.

Flux 3 offers a free tier to start, plus monthly or annual subscription plans billed in credits: Basic at $7.50/mo, Pro at $19.50/mo, and Max at $80.00/mo, alongside one-time credit packs. The site is an independent web interface for Flux 3 and does not resell raw API access, though a provider API exists for developers.
