Released October 1, 2026, FLUX 3 Image is the image pillar of Black Forest Labs' FLUX 3 ecosystem — native 4K output, multi-step local editing, up to 10 reference images, and a bounding-box system that lets you place elements on a grid before the render.

Black Forest Labs released FLUX 3 Image on October 1, 2026 — the dedicated image-generation and editing model that was promised when the lab unveiled its broader FLUX 3 multimodal effort on July 23, 2026. FLUX 3 Image is the image half of that ecosystem, which also spans FLUX 3 Video, a robotics action model, and a planned open-weight FLUX 3 Dev. This release is specifically about stills: generation, editing, and composition.
The headline features are layout control and high resolution. FLUX 3 Image uses a bounding-box composition system — you place named elements on a normalized 0–1000 grid, in any aspect ratio, and the model renders the whole frame respecting those boxes. It can also plan a layout for you from a single-line prompt using an LLM step. It renders natively up to 4K (about 16 megapixels) without a separate upscaling pass, accepts up to 10 reference images as composition guidance, and supports multi-step local editing that Black Forest Labs says leaves the unedited regions of an image largely untouched.
Access is through the BFL API — a single POST to the FLUX 3 Image endpoint with an API key, where only a prompt is strictly required. Pricing is per image and scales with resolution: Black Forest Labs lists roughly $0.041 at 768px up to about $0.607 at 4K, with a 50% launch discount running through October 8, 2026. The lab also offers commercial weights licensing, fine-tuning, and self-hosted deployment for companies generating at scale. Confirm current pricing and tiers on Black Forest Labs' own pages before budgeting against them.
One honest caveat: at launch FLUX 3 Image had no entries on independent leaderboards like Artificial Analysis or Arena, and Black Forest Labs' own materials describe edit preservation in qualified terms ("usually" identical outside the edited region). So treat the quality and editing-reliability claims as promising but not yet independently benchmarked.
A FLUX 3 Image render is a strong starting frame, not a finished post. The bounding-box control is genuinely useful for getting a composed, on-brand product or editorial image on the first try — but a 4K PNG sitting in your downloads has no caption, no per-platform crop, no surrounding copy, and no schedule. Kompozy is the layer that acts on it. Pull a FLUX 3 Image still in as a source and Kompozy fans it into a finished batch: a brand-exact multi-slide Carousel rendered through HyperFrames, Photo Posts reframed to 9:16, 1:1, and 16:9 for each destination, a Quote Graphic, and platform-native captions written in your voice through the Persona Brief.
The same still also seeds formats a raw image model doesn't make. Kompozy can set a FLUX 3 Image frame behind a Listicle Video with title and body cards, or spin the concept into a Blog Article and an Email Newsletter — then schedule and publish the whole set across eight social platforms plus blog and email from one queue with Autopilot and a per-post review pass. FLUX 3 Image owns the pixels; Kompozy owns the captions, the formats, the crops, and the publish.
FLUX 3 Image is Black Forest Labs' dedicated image-generation and editing model, released October 1, 2026. It is the image component of the broader FLUX 3 ecosystem (which also includes video and robotics models). Its standout features are a bounding-box layout system, native 4K rendering, up to 10 reference images, and multi-step local editing.
FLUX 3 is Black Forest Labs' broader multimodal effort unveiled on July 23, 2026, spanning video (with native audio), a robotics action model, and planned open weights. FLUX 3 Image, released October 1, 2026, is specifically the image generation and editing pillar — text-to-image, editing, and bounding-box composition, rather than video.
Black Forest Labs prices FLUX 3 Image per image by resolution through its API — roughly $0.041 at 768px up to about $0.607 at 4K — with a 50% launch discount running through October 8, 2026, plus commercial weights licensing for self-hosting. Pricing moves, so confirm current figures on Black Forest Labs' own pages.
No. FLUX 3 Image generates and edits image files through an API; it does not caption, reframe per platform, or publish anything. To turn its output into finished posts, carousels, and a blog scheduled across platforms, pair it with a content engine like Kompozy that ingests the still and distributes it.
