Black Forest Labs launched FLUX 3 Image on October 2, introducing an image generator and editor built around bounding boxes: users can specify where elements should appear, then revise selected parts of an image while leaving untouched areas intact. The model is available through the company’s API and Playground, with native 2K and 4K output and support for up to 10 reference images.
Bounding boxes put users in control of placement
Rather than relying only on a text prompt to describe a composition, FLUX 3 Image lets users draw a box for each element and describe what belongs inside it. A global prompt ties the elements together; the model generates the image with those elements placed within their assigned regions. Black Forest Labs also says an LLM agent can plan the layout from a short instruction, leaving the boxes editable.
The same box-based approach applies to revisions. Users can move an element, replace it or change its description, and the company says other parts of the image remain unchanged. The model page presents examples including adding divers to an existing image, replacing an object and changing a person’s hair color.
Four-kilopixel output and ten image references
FLUX 3 Image accepts as many as 10 reference images for a single composition, which the model places and scales according to the prompt. Black Forest Labs says it generates at native 2K and 4K resolution. One example on the product page is listed at 5,456 by 3,072 pixels, or 16.8 megapixels.
The company describes the model as supporting text-to-image and image-to-image generation, along with detailed text rendering and editing. Those are company claims; the announcement does not provide an independent benchmark or a comparative test against other image models.
API discount now, open weights later
Black Forest Labs is cutting API use of FLUX 3 Image by 50% through October 8. Its launch post does not give a standard per-image price, so the discount alone does not establish what a generation costs.
An open-weights version is planned “in the coming weeks,” according to the company, but the post does not specify a release date. Separately, Black Forest Labs says it is making the model available under a commercial weights license for companies that want to fine-tune it and run image generation on their own infrastructure. That license offers a route to self-hosting for commercial customers; the open-weights release is not available yet.
Two routes beyond the hosted Playground
The launch separates immediate access from future or licensed deployment. Users can try the hosted model now through the Playground or API, while companies seeking their own infrastructure can contact Black Forest Labs about the commercial weights license. Broader access to downloadable weights depends on the promised release in the coming weeks.
For now, the most concrete change is the editing workflow: FLUX 3 Image combines spatial instructions, reference images and successive targeted edits in one product. Black Forest Labs’ launch terms are equally specific: API users get half-price access through October 8, while the company has not yet dated the open-weights release.
