Through October 8, 2026, Black Forest Labs offers a 50 percent introductory discount on Flux 3 Image API, pricing entry-level images at $0.0205 per image at 768px.

Flux 3 Image accepts up to ten reference images per generation, which can be supplied as URLs or base64-encoded data.

Pixel-preservation editing is now a baseline standard rather than a key competitive differentiator for AI image generators

Black Forest Labs said the price of a 1K-resolution image on the Flux 3 Image API will increase to approximately $0.048 after the introductory discount window closes

When editing a selected bounding box, Flux 3 Image regenerates only the specified region while leaving all pixels outside that box numerically unchanged

Bit-identical pixel preservation is essential for professional AI image editing

Programmatic JSON layouts are superior to natural-language prompting for AI image editing

Flux 3 Image includes a prompt upsampler that expands short instructions, but stable box IDs and coordinate arrays bypass this rewrite step to reach the model unchanged
