Flux 3 Max

• 🆕 Black Forest Labs' top-tier Flux 3 text-to-video generation endpoint
• 🎬 Turns a text prompt into clips with synchronized audio
• 📏 Up to 20 seconds, FHD 1920×1088, 24 fps per request
• 💬 Multilingual speech with strong lipsync, effects and ambience
• 🧠 Built on one multimodal model trained jointly across images, video, audio
• ⚡ Draft mode previews ideas cheaply before full-quality rendering
• 🔧 Keyframes, continuation and agentic chaining into multi-shot sequences
• 🏢 From Freiburg-based Black Forest Labs, founded by ex-Stability AI staff

Black Forest Labs

Black Forest Labs is a generative AI company based in Freiburg im Breisgau, Germany, founded by former members of Stability AI. The lab is best known for developing the Flux family of text-to-image models, which generate images from natural language prompts…

Flux 3 Max is the highest-tier text-to-video configuration of Black Forest Labs' Flux 3 line, generating a video clip — with sound — directly from a written prompt. Per BFL's documentation, a single request can return up to 20 seconds at FHD resolution (1920 × 1088 for 16:9) at 24 fps, with multilingual speech, effects and ambience produced alongside the frames rather than dubbed in afterwards.

The jump from the previous generation is structural. The Flux 2 family on this catalog — Flux 2 Pro, Flux 2 Max and the editing-oriented Flux 2 Max Edit — is image-only. Flux 3 is described by BFL as a single multimodal model that mixes modalities and can generate images and video-with-audio jointly, from text alone or from image and video references; in preliminary midtraining evaluations the lab reports significant improvement over earlier Flux versions on complex prompts and text generation.

Within Flux 3, this entry is the Max-tier sibling of Flux 3 text-to-video and complements Flux 3 Max image-to-video, as well as Flux 3 First Last Frame and Flux 3 Extend. The same underlying model also powers Flux 3 image generation and Flux 3 editing.

Supporting features documented by BFL include keyframe control, video-to-video reference transfer, generative video-audio continuation, broad style range, and agentic chaining of clips into longer multi-shot sequences. A draft mode returns a fast, low-cost preview that can later be re-rendered at full quality.
