FLUX 3: Black Forest Labs' Multimodal AI Model

FLUX 3 is Black Forest Labs' first truly integrated foundation model, unveiled in early access on July 23, 2026.

Instead of doing one thing, it works across images, video, audio and physical action prediction inside a single architecture, built on the company's Self-Flow approach for aligning multimodal generation and understanding.

The headline capability is text-to-video that produces clips up to 20 seconds long with native audio in sync with the visuals, dialogue, sound effects and ambient noise all matched to what is on screen.

Here is how the family breaks down.

FLUX 3's leap is that generation and understanding share one model across modalities.

In practice that means a single prompt can drive a video with matching audio, an image, or an action sequence, without stitching separate tools together.

The video side is the standout: up to 20-second clips with native audio, where dialogue, sound effects and ambient sound stay aligned with the picture, something most text-to-video models still handle as a separate step.

The Action variant, FLUX-mimic, extends the same architecture to predicting physical movement for robotics.

Black Forest Labs staged the launch rather than shipping everything at once. FLUX 3 Video went out first, in early access through an API and private weights to initial partners.

FLUX 3 Action / FLUX-mimic reached selected research and commercial robotics partners. FLUX 3 Image, the part most creators will use, is rolling out in the coming weeks.

An open-weight FLUX 3 Dev is planned for later in 2026 for developers who want to self-host. So if you cannot access it yet, that is expected, broad availability is still ramping.

FLUX.2, released in November 2025, is an image model: strong multi-reference editing, 4-megapixel output and sharp text. FLUX 3 is a different class of product, a multimodal model that adds video with synced audio and physical-action prediction on top of imagery.

If you need production image generation today, FLUX.2 is the widely available choice. If you are tracking where AI video is going, FLUX 3's 20-second, audio-synced clips are the headline.

For most creators the practical path is to use FLUX.2 images now and adopt FLUX 3 video as its image and open-weight tiers become available.

During early access FLUX 3 Video and Action are limited to Black Forest Labs' partners via API and private weights, with FLUX 3 Image arriving for broader use in the coming weeks and an open-weight Dev release later in 2026.

If your goal is finished video today, without waiting on early-access slots, FluxNote already turns a prompt into a narrated, captioned video using current top models, and generates FLUX-style images in its Image Studio, so you can produce and publish now and fold in FLUX 3 as it opens up.
