Black Forest Labs' dedicated image model — bounding-box layout control, native 4K output, up to 10 reference images, and targeted multi-step editing.

FLUX 3 Image is Black Forest Labs' dedicated text-to-image and image-editing model, released on October 1, 2026. It's the image pillar of the broader FLUX 3 ecosystem the lab unveiled in July 2026 — which also spans a video model, a robotics action model, and a planned open-weight FLUX 3 Dev. Black Forest Labs is the German studio founded by several of Stable Diffusion's original researchers, and FLUX 3 Image is its most control-focused release.
The defining feature is composition. Rather than re-rolling a prompt and hoping elements land where you want, FLUX 3 Image lets you place named elements as bounding boxes on a normalized 0–1000 grid, in any aspect ratio, and renders the whole frame respecting those boxes — or it can plan the layout for you from a single-line prompt using an LLM step. That makes it well suited to editorial layouts, typography, product scenes, collages, and panel grids where spatial relationships matter.
On output, it renders natively up to 4K (about 16 megapixels) without a separate upscaling pass, accepts up to 10 reference images supplied as URLs or base64 for style and asset guidance, supports targeted multi-step local editing that aims to leave unedited regions intact, and can use search grounding to pull in web and image references. Access is through the BFL API — a single request where only a prompt is required — plus commercial weights licensing, fine-tuning, and self-hosting for scale.
Pricing is per image and scales with resolution (roughly $0.041 at 768px up to about $0.607 at 4K at launch, with a 50% launch discount through October 8, 2026). Black Forest Labs published no independent benchmark results at launch and describes edit preservation in qualified terms, so treat the quality and reliability claims as promising but not yet third-party verified; confirm current specs and pricing on the lab's own pages.
FLUX 3 Image is unusually good at one thing most generators fumble: putting the elements exactly where you want them. That precision is what makes it worth pairing with Kompozy — because a perfectly composed 4K still is still a static file, and a static file is the start of a post, not the post. The most useful move is turning that one frame into motion and volume. Drop a FLUX 3 Image still into Kompozy and it can sit the image behind a Listicle Video with title and body cards, animate into short-form video that actually survives a feed that autoplays muted, and reframe to 9:16, 1:1, and 16:9 so the same composition works on every destination.
Then Kompozy fans the single frame into a whole content unit a model can't assemble on its own. Its HyperFrames engine renders brand-exact multi-slide Carousels from the image and your copy; the Persona Brief writes platform-native captions in your voice; and the concept spins out into Photo Posts, a Quote Graphic, a Blog Article, and an Email Newsletter. FLUX 3 Image controls the pixels inside the frame with its bounding boxes; Kompozy controls everything around the frame — motion, formats, captions, crops, and the scheduled publish across eight social platforms plus blog and email. If you also need a recurring face across posts, Kompozy's Gemini face-locked Persona Photos complement FLUX 3 Image's scene control rather than competing with it.
FLUX 3 Image is Black Forest Labs' dedicated image-generation and editing model, released October 1, 2026. It is the image pillar of the broader FLUX 3 ecosystem, and its standout features are a bounding-box layout system, native 4K rendering, up to 10 reference images, and targeted multi-step local editing.
Its bounding-box composition system. You place named elements on a normalized 0–1000 grid before the render, in any aspect ratio, and the model fills the frame respecting them — a more repeatable way to control layout than re-rolling a prompt. It pairs that with native 4K output, up to 10 reference images, and local multi-step editing.
It is priced per image by resolution through the BFL API — roughly $0.041 at 768px up to about $0.607 at 4K at launch, with a 50% discount through October 8, 2026 — plus commercial weights licensing for self-hosting. The 4K tier costs several times a 1K render. Confirm current pricing on Black Forest Labs' pages.
FLUX 3 Image renders the image but doesn't publish it. Bring the still into Kompozy to animate it into short-form video and Listicle Video, reframe per platform, build a brand-exact carousel and quote graphic from it, write captions in your voice, and schedule and publish across eight social platforms plus blog and email from one queue.
