FLUX 3 Image pricing
Priced per image by output resolution, flat across text-to-image and image-to-image. No subscription, no minimums, with the same key and billing as every other model on Runware.
One model, four ways to build an image
FLUX 3 Image can generate an entirely new image from a written prompt, compose from multiple reference images at once, make a precise local edit to an existing image, or render and edit text inside the frame.
Text to image
A prompt alone is enough. FLUX 3 Image generates natively at up to 4K, across 15 aspect ratios from 21:9 to 9:21.
Multi-reference generation
Attach up to 10 reference images and compose them into one consistent scene, with faces, outfits, products, and objects held recognisable across the result.
Local editing
Edit part of an existing image while the rest of the frame stays untouched. Relight a scene, remove a subject, or adjust one detail without regenerating everything around it.
Text rendering & editing
Render multilingual text directly inside a generation, or edit text already inside an existing image while keeping the original font, weight, and lighting.
Why FLUX 3 Image stands out
Native 4K generation
Generates directly at up to 4K resolution rather than upscaling a smaller output, across 15 aspect ratios from 21:9 to 9:21.
Multi-reference generation and editing
Up to 10 reference images composed into one consistent result in a single call, with no separate merge or compositing pass required.
Precise local editing
Edit one part of an image, a subject, a light source, a detail, while the rest of the frame stays exactly as it was.
Layout control with bounding boxes
Place every element where you want it. Give each one an id and a bounding box on a 0–1000 scale in a JSON table inside the prompt, for new generations and targeted edits alike.
Text rendering and editing
Multilingual text rendered directly inside a generation, or edited inside an existing image while keeping the original font, weight, and lighting.
Stronger prompt adherence
A generational step up in following complex, multi-subject prompts. Several distinct actions in one frame, each rendered as written rather than blended together.

Real FLUX 3 Image generations: a text-to-image gallery, multi-reference composition, local editing, bounding-box edits, complex prompt adherence, and text rendering.
1 / 7Built for real workflows
FLUX 3 Image is Black Forest Labs' first image model on the FLUX 3 backbone. It handles generation and editing through the same model and the same request shape, so a workflow doesn't need separate tools for each step.
Product and packshot photography
Generate clean, native-4K product shots and compose the same product across multiple scenes from a single reference image.
Multi-reference composition
Combine up to 10 reference images, a face, an outfit, a product, a setting, into one consistent scene without a separate compositing pass.
Iterative local edits
Relight a scene, remove a subject, or adjust one detail on an existing image, without regenerating everything around it.
Marketing and campaign creative
Fashion editorials, beauty photography, and documentary-style scenes rendered with strong adherence to detailed, multi-subject prompts.
Localized in-image text
Render multilingual text directly inside a generation, or edit text already inside an existing image while keeping the original font, weight, and lighting.
Poster and layout design
Typographic layouts, gig posters, and packaging comps with legible rendered text, not text stitched in afterward.

]Frequently asked questions
What is FLUX 3 Image?
Black Forest Labs' first image model built on the FLUX 3 multimodal backbone, the same architecture behind FLUX 3 Video. It generates natively at 4K, accepts up to 10 reference images in one generation, edits existing images without disturbing the rest of the frame, and renders and edits text with high accuracy.
Does FLUX 3 Image handle editing as well as generation?
Yes. Generation and editing run through the same model and the same request shape. That covers local edits that leave the rest of the frame untouched, multi-reference composition from up to 10 images, and text editing inside an existing frame while keeping the original font, weight and lighting.
How many reference images can FLUX 3 Image use at once?
Up to 10 reference images in a single generation. The model keeps characters, products and objects recognisable across an edit and across a composition that pulls from several references at once.
What resolutions does FLUX 3 Image support?
Four tiers: 0.75K, 1K, 2K and 4K. Set them via width/height presets for a plain generation, or via the resolution parameter once at least one reference image is attached, which then matches the reference's aspect ratio automatically.
How much does FLUX 3 Image cost on Runware?
From $0.041 per image, flat across text-to-image and image-to-image, so only the resolution changes the price. See the pricing page for the full breakdown and every other model's rates.
Can I use FLUX 3 Image through the Runware API?
Yes. FLUX 3 Image is available now through both the Runware Playground and API, under the AIR ID bfl:flux@3-image.
Is FLUX 3 Video also available on Runware?
Yes. FLUX 3 Video, the video half of the same FLUX 3 model line, is also live on Runware.
