What Makes the FLUX 3 API Different

Confirmed FLUX capabilities from Black Forest Labs' early-access announcement

FLUX Multimodal Foundation Model

The FLUX 3 API is based on a model that jointly learns images, video, audio, and action prediction in one architecture instead of isolating each generation task.

Video with Native Audio

The preview highlights synchronized visuals and sound, including dialogue, ambience, and event-aligned audio, without a separate audio-generation stage.

Up to 20-Second Video

For this model, BFL states that video with native audio can reach 20 seconds in one generation, with longer sequences built through chaining and references.

FLUX Video Workflows

The FLUX 3 API capability announcement includes text-to-video, image-to-video, video-to-video, keyframe guidance, video continuation, and video-plus-audio continuation.

FLUX Reference-Guided Generation

The FLUX 3 API preview combines text with image or video references to guide subjects, visual identity, motion, composition, and continuity.

FLUX Image Creation and Editing

The FLUX 3 API model can create or edit images across styles, aspect ratios, and resolutions while retaining the multimodal understanding used for video.

FLUX Prompt and Typography Control

The model improves complex-instruction adherence and supports typography and animated video designs, while BFL reports more accurate multilingual image text.

FLUX Action Prediction

The FLUX 3 API model extends its understanding of visual dynamics toward action prediction. APIMart availability will depend on the final integration.

Potential FLUX 3 API Workflows

Creative and production scenarios for future FLUX workflows across connected media

FLUX Storyboards and Pre-Visualization

A future FLUX 3 API workflow could turn scripts, keyframes, and reference footage into sequences with motion and native sound for production planning.

Multilingual Campaign Creative

Teams could use the FLUX 3 API to develop localized visuals and video concepts with multilingual dialogue and on-screen text from one creative direction.

FLUX Product Images and Video

A future FLUX 3 API workflow could use product references for campaign images, demonstrations, and short video variations with recognizable subjects.

FLUX Image Generation and Editing

Creators could use the FLUX 3 API to generate assets or revise images through natural-language instructions across styles, formats, aspect ratios, and resolutions.

FLUX Video Continuation and Re-Styling

A future FLUX 3 API workflow could continue clips, transform visual style, or guide motion from a starting frame, keyframes, or reference video.

Connected Creative Pipelines

The FLUX 3 API could connect image concepts, video, and native audio in one model family, reducing handoffs between separate tools during iteration.

FLUX 3 API Frequently Asked Questions

What Black Forest Labs has confirmed about the FLUX 3 API model and upcoming APIMart availability

What is the FLUX 3 API?

The FLUX 3 API refers to access for Black Forest Labs' multimodal foundation model across image, video, audio, and action prediction, with text and visual reference inputs.

When will the FLUX 3 API be available on APIMart?

The FLUX 3 API is coming soon to APIMart. No launch date has been announced. Supported modalities, documentation, limits, and pricing will be published when integration is ready.

Can the FLUX 3 API generate video with audio?

BFL describes the FLUX 3 API model as generating video and native audio together, including multilingual dialogue, ambience, and sounds associated with scene events.

How long can a FLUX 3 API video be?

For the FLUX 3 API model, BFL states that video with native audio can reach 20 seconds in one generation. Longer sequences may use chaining and references; APIMart limits remain unconfirmed.

Which FLUX 3 API video workflows are announced?

The FLUX 3 API capability announcement includes text-to-video, image-to-video, video-to-video, keyframe-to-video, video continuation, video-plus-audio continuation, and reference guidance.

Can the FLUX 3 API generate and edit images?

BFL says the FLUX 3 API model can synthesize and edit images across styles, aspect ratios, and resolutions, with better handling of complex prompts and multilingual text.

What does action prediction mean for the FLUX 3 API?

Within the FLUX 3 API model, action prediction uses learned visual dynamics to anticipate what may happen next. APIMart has not confirmed access to this capability.

Will every FLUX 3 API modality be available through APIMart?

The final FLUX 3 API integration scope has not been announced. Supported modalities, request formats, output limits, commercial terms, and pricing will be published when access becomes available.
