FLUX 3 Image

FLUX 3 Image is a flagship image generation and editing model developed by Black Forest Labs, built to offer fine-grained control over complex visual compositions. Released on October 1, 2026, the model integrates advanced multimodal reference handling and layout management within a single pipeline. It is designed to address common visual layout challenges by allowing precise local edits while preserving the overall coherence of untouched regions.

Core Capabilities and Architecture

The model supports native high-resolution rendering up to 2K and 4K resolutions, alongside flexible aspect ratios across fixed tiers. A key feature of FLUX 3 Image is its layout control via named elements and bounding boxes, enabling users to specify exact spatial positioning for subjects and objects on a canvas prior to rendering. Additionally, it supports multi-reference workflows capable of combining up to 10 input reference images into a unified, balanced composition.

Editing and Prompt Workflow

FLUX 3 Image introduces targeted, pixel-level multi-turn editing capabilities that let creators modify, replace, or move individual sections of an existing image without altering the rest of the scene. This structural separation of elements makes it suitable for complex editorial layouts, product visualization, and design iterations where precise placement and background consistency are paramount.
