Give each reference a role
Say what to take from each upload, for example: use image 1 for the face, image 2 for the jacket, and image 3 for the street.

Image: Black Forest LabsWhat is FLUX 3?
FLUX 3 is Black Forest Labs' third-generation model family. The family was announced on July 23, 2026 as one multimodal model for image, video, audio, and action generation. FLUX 3 Image, the image generation and editing model on this page, was released on October 1, 2026. It succeeds FLUX.2 (November 2025) and focuses on control: native high resolution, up to ten references, bounding-box layouts, and multi-step edits that leave the rest of the picture unchanged.

How to use FLUX 3 online
- 01
Write the brief
Describe the subject first, then the setting, composition, lighting, and style. Put any exact on-image text in quotes.
- 02
Add references (optional)
Switch to image mode and upload up to 10 images for a person, product, outfit, or location. Files above 4 MP are resized before upload, the largest size FLUX 3 accepts.
- 03
Choose canvas and resolution
Pick one of 14 aspect ratios. Use 1K for drafts, 2K for web and social, and 4K for print or large crops. The credit cost updates before you submit.
- 04
Generate and download
Each run returns one JPEG. Lower resolutions return fastest; Fal notes that 4K can take several minutes. Download the result or continue in the layer tools.
FLUX 3 pricing
On Image to Layers, each FLUX 3 image costs a fixed number of credits by resolution. Reference images add no surcharge, and failed generations are refunded automatically. For developers, Black Forest Labs publishes per-image API prices by resolution as well.
| Resolution | Approx. size | Credits here | BFL API list price |
|---|---|---|---|
| 1K | About 1 MP | 10 credits | $0.048 |
| 2K | About 4 MP | 20 credits | $0.100 |
| 4K | About 16 MP, up to 5456 × 3072 | 120 credits | $0.607 |
BFL list prices are taken from its pricing documentation on October 7, 2026 (1 BFL credit = $0.01). BFL ran a 50% launch discount through October 8, 2026, and also sells a 768 × 768 tier at $0.041 that this workspace does not offer.
BFL pricing documentationFLUX 3 image editing with up to 10 references
Switch the studio to image mode, upload one to ten references, and describe the change. FLUX 3 is designed to change only what you ask for, so you can refine one area across several runs while the rest of the picture stays the same.
Edit one region at a time
Ask for one change per run, such as recoloring a sofa or removing a sign. Black Forest Labs built FLUX 3 to keep untouched areas unchanged across multiple edits.
Each reference: 256 px to 4 MP
Fal accepts references of at least 256 pixels per side and at most 4 megapixels. The studio downsizes larger files automatically; images that are too small are rejected.
Official before and after edits
Black Forest Labs published these edits in its bounding-box guide, with the share of pixels that stayed identical to the source.

Image: Black Forest LabsPlace elements with bounding boxes
FLUX 3 has no separate layout setting. Name each element in the prompt with a tag such as <bottle_1>, then append a JSON array of rows. Each box is [top, left, bottom, right] on a 0–1000 grid measured from the top-left corner, so [0, 0, 500, 500] is the top-left quarter of any canvas.
Minimal square poster for a perfume launch: a headline <headline_1> across the top, a clear faceted glass perfume bottle <bottle_1> in the center, and a pale travertine plinth <plinth_1> beneath it, on a warm sand-colored studio background. [{"id":"headline_1","bbox":[60,150,200,850],"desc":"text reading \"GOLDEN HOUR\" in a thin, widely spaced serif, dark brown"},{"id":"bottle_1","bbox":[260,330,760,670],"desc":"a clear faceted glass perfume bottle with amber liquid and a brass cap, soft caustic highlights"},{"id":"plinth_1","bbox":[740,230,950,770],"desc":"a pale travertine plinth with a soft contact shadow"}]Keep the aspect ratio you designed the boxes for, give each line of text its own box with the exact words in quotes, and avoid tiny boxes. Boxes guide placement; they are not hard masks.
FLUX 3 prompting guide
Write FLUX 3 prompts as a visual brief rather than a keyword list: subject and action first, then setting, composition, lighting, style, and any exact text. Each example below loads into the studio with its aspect ratio and resolution.
Prompt formula:Subject and action → setting → composition → lighting → style → exact text in quotes
Ecommerce · 4:5 · 2K
Product ad with an exact headline
Premium product advertisement of a matte black insulated water bottle standing on wet slate, cold mist around its base, crisp side light with a soft rim highlight, shallow depth of field, dark charcoal background. Above the bottle, the headline text reading "STAY COLD 24H" in bold condensed sans-serif, centered, white. Photorealistic commercial photography with generous negative space.
Quoting the headline and naming its font style helps FLUX 3 render legible text in the right place.
Portrait · 2:3 · 1K
Editorial portrait
Editorial portrait of an elderly ceramic artist in her studio, seated at a pottery wheel with clay-covered hands, medium shot from slightly below eye level, warm late-afternoon window light from the left, shelves of glazed bowls softly out of focus behind her, natural skin texture, muted earthy palette, 85mm lens look, subtle film grain.
Camera distance, light direction, and lens look give the model concrete photographic choices instead of vague quality words.
Reference edit · 16:9 · 2K
Multi-reference campaign shot
Use image 1 for the model's face and hairstyle, image 2 for the denim jacket, and image 3 for the street location. Show the model walking toward the camera on that street at golden hour, full-body shot, the jacket's stitching and wash clearly visible, soft motion blur in the background crowd, realistic fashion campaign photography.
Assigning one job to each reference keeps the face, product, and location from blending together.
Layout · 1:1 · 1K
Bounding-box poster layout
Minimal square poster for a perfume launch: a headline <headline_1> across the top, a clear faceted glass perfume bottle <bottle_1> in the center, and a pale travertine plinth <plinth_1> beneath it, on a warm sand-colored studio background. [{"id":"headline_1","bbox":[60,150,200,850],"desc":"text reading \"GOLDEN HOUR\" in a thin, widely spaced serif, dark brown"},{"id":"bottle_1","bbox":[260,330,760,670],"desc":"a clear faceted glass perfume bottle with amber liquid and a brass cap, soft caustic highlights"},{"id":"plinth_1","bbox":[740,230,950,770],"desc":"a pale travertine plinth with a soft contact shadow"}]
The caption names three elements and the JSON rows fix where each one sits on the 0–1000 grid.
Reference examples switch the studio to image mode. Add your own uploads before generating.
FLUX 3 vs other image models

Specifications reflect the versions offered in this workspace on October 7, 2026.
FLUX 3 vs FLUX.2
Compared with FLUX.2 (November 2025), which generated up to about 4 MP, FLUX 3 Image adds native 4K output of about 16 MP, prompt-level bounding-box layouts, and multi-turn edits designed to keep unedited pixels unchanged. FLUX 3 Image is a single model rather than separate pro, flex, or dev variants; resolution is the only setting that changes its price.
FLUX 3 FAQ
Is FLUX 3 free to use?
Not here. Image to Layers does not give free signup credits, and each FLUX 3 image uses credits: 10 at 1K, 20 at 2K, or 120 at 4K. The smallest purchase is a $5 trial pack with 100 credits, enough for 10 FLUX 3 images at 1K. Black Forest Labs also offers FLUX 3 in its own Playground at its API prices.
When was FLUX 3 released?
Black Forest Labs announced the FLUX 3 family on July 23, 2026 and released FLUX 3 Image, its image generation and editing model, on October 1, 2026. FLUX 3 follows FLUX.2, which was released in November 2025.
Is FLUX 3 open source?
Not yet. Commercial weights for self-hosting and fine-tuning are available from Black Forest Labs by request, and BFL has said public weights will follow. As of October 7, 2026 no public download or license has been published. Earlier FLUX releases used both non-commercial and Apache 2.0 licenses, so check the final terms when they appear.
Is FLUX 3 Image the same as FLUX 3 Video?
No. They are separate products in the FLUX 3 family with separate APIs and pricing. FLUX 3 Video generates clips with synchronized audio and is billed per second of output. This page offers only FLUX 3 Image, billed per image.
How much does the FLUX 3 API cost?
Black Forest Labs lists FLUX 3 Image at $0.048 per 1K image, $0.100 per 2K image, and $0.607 per 4K image, plus a 768 × 768 tier at $0.041. The API is also offered by providers such as Fal and Replicate. In this workspace you pay with site credits instead and need no API key.
How many reference images can FLUX 3 use?
Up to 10 per request. On Fal, each reference must be at least 256 pixels per side and no larger than 4 megapixels; this studio resizes larger uploads automatically. Tell the model what each reference contributes, such as a face, a product, or a location.
What resolution does FLUX 3 support?
FLUX 3 renders natively, without an upscaling pass, at about 1 MP (1K), 4 MP (2K), or 16 MP (4K), up to 5456 × 3072 pixels. This workspace offers 1K, 2K, and 4K with 14 aspect ratios from 21:9 to 1:2.
Why is there no seed or batch setting?
The FLUX 3 Image API does not accept a seed, and each request returns one image. To compare options, run the same prompt again or change one detail at a time.
Is this the official FLUX 3 website?
No. Image to Layers is an independent workspace and is not affiliated with Black Forest Labs. Requests run on the official FLUX 3 Image model through Fal's API. Results are saved privately in your account, and downloads have no added watermark.
