Flux Kontext Dev is an advanced image generation tool that empowers artists, designers, and AI researchers to edit existing visuals using nothing but text prompts. With key features like multi-layered image editing, embedded style and object memory, and robust consistency through successive edits, Flux Kontext Dev generates highly accurate, stylized, and refined imagery for a variety of creative workflows.

Features Of Flux Kontext Dev For Creators

Edit Existing Images with Text Prompts

With Flux Kontext Dev, you can change any existing image by simply describing your desired edits in words. Whether replacing objects or shifting mood, this advanced rectified flow transformer interprets your input with high precision. Flux Kontext Dev uses its 12B parameters to deliver dynamic image generation while giving you full creative control.

No Finetuning Needed for Style or Object Recall

You no longer need tedious finetuning to apply a specific artistic style or reference a known object. With Flux Kontext Dev, this capability is embedded out of the box. The model remembers visual elements and easily applies them across multiple tasks, giving Flux Kontext Dev a powerful edge in consistent visual generation and workflow efficiency.

Refine Visuals Through Successive Image Edits

Visual consistency across multiple edits is no longer a challenge. Flux Kontext Dev allows you to perform iterative refinements on an image with minimal visual drift. This feature supports creative feedback loops and detailed variations, making Flux Kontext Dev ideal for workflows where precision and coherence matter most.

Open-Access Model Fuels Innovation in AI Art

By providing open weights, Flux Kontext Dev empowers researchers and artists to explore novel transformations and remix techniques. This transparency supports reproducible AI research and creative exploration alike. Flux Kontext Dev becomes not just a generation tool, but a catalyst for future-forward experimentation in image editing AI.
