FLUX 3 Image Launches: Native 4K Output, Multi-Image Reference Editing
Black Forest Labs released the image model FLUX 3 Image on October 1. A single request accepts up to 10 reference images, supports natural-language local editing, with native output up to 4K. API is half-price at launch; the open-weight version is expected within weeks.
What Launched
On October 1, German company Black Forest Labs released FLUX 3 Image. It’s the image-side model of the FLUX 3 series, shipping in two versions at once (FLUX 3 Image and FLUX 3 Image Edit). Free trial is already open.
The FLUX 3 series had previously only shown its video model, FLUX 3 Video. With image added, the lineup now spans video and image. The company also previewed what’s next: the FLUX 3 Action robot-action model and the FLUX 3 Dev open-weight release.
Editing Is the Core Sell
FLUX 3 Image leads with editing.
The official flow: modify a single object in the frame with natural-language instructions — recolor it, move it, swap it for something else. Background, lighting, and camera angle stay put. Keep editing across rounds.
Reference images go up to 10. One request can take up to 10 input images for cross-image style transfer, character consistency, or compositing material from multiple images into one frame.
Composition control uses bounding boxes. On a normalized 0–1000 coordinate grid, each element gets an ID, a text description, and a precise bounding box; the model lays out the frame by the boxes. The design comes from the FLUX 3 base — the pitch is “placed exactly right.”
4K Is Native Output, Not Post-Upscaling
Resolution comes in tiers: 768px, 1K, 1.5K, 2K, 4K — five stops, with 4K at 16 megapixels. Aspect ratios run from 21:9 panoramas to 9:21 portraits.
The key word is “native.” 4K resolution is generated directly in one pass, no post-generation upscaler — officially, details don’t smear after enlargement.
There’s also an optional web-retrieval toggle. Turned on, the model retrieves web data and real images before generating, to keep historical and contemporary subjects temporally accurate.
Pricing and Access
API is priced per image by resolution tier: $0.0205 per image at 768px, $0.024 at 1K, $0.3035 at 4K. Everything is half-price through October 8.
Enterprise users can buy commercial weight licenses to deploy and fine-tune the model on their own infrastructure. Community users are waiting on the open-weight release, officially “in the coming weeks.”
A Rival Moved at Almost the Same Time
Days before FLUX 3 Image, Ideogram announced its own editing-oriented 4.5 model. Same editing focus, same open-weight plans. Two launches colliding in the same window — image editing is going to be busy for the next few months.
For ordinary users, the free demo is worth trying. For developers, watch the open-weight release’s real-world performance once it lands, and the official pricing after the half-price window (through October 8) ends.
