Beyond Text-to-Image: Context is Key

Developed by Black Forest Labs, FLUX.1 Kontext is not just another text-to-image model. Its architecture is designed to understand and process existing images as input, enabling flexible and instantaneous editing without complex workflows. This marks a significant step towards more interactive and intuitive creative processes.

The FLUX.1 Kontext Suite

The FLUX.1 Kontext family includes several models, each tailored for specific needs, from open-source development to premium commercial performance.

FLUX.1 Kontext [max]

The premium model offering maximum performance, greatly improved prompt adherence, and superior typography generation for editing without compromise.

FLUX.1 Kontext [pro]

A unified model for local editing, generative modifications, and text-to-image generation. Pioneers iterative workflows with character consistency.

FLUX.1 Kontext [dev]

An open-weights, 12B parameter model that delivers proprietary-level image editing performance on consumer hardware.

Core Capabilities

FLUX.1 Kontext introduces a suite of powerful features that redefine image editing and generation. These capabilities are built on its deep understanding of image content and context.

Character Consistency

Preserve unique elements of an image, such as a character or object, across multiple scenes and environments with remarkable fidelity.

Local Editing

Make targeted modifications to specific elements in an image using simple text instructions, without affecting the rest of the composition.

Style Reference

Generate entirely new scenes while preserving the unique artistic style from a reference image, all guided by text prompts.

Interactive Speed and Iterative Workflow

One of the standout features of FLUX.1 Kontext is its minimal latency. This allows for a truly iterative workflow where you can add more instructions and build upon previous edits step-by-step, refining your creation in real-time while preserving image quality and character consistency. This is a significant advantage over models that require re-generating the entire image for each change.

Competitive Landscape

FLUX.1 Kontext enters a competitive field, but its unique editing and context-aware features set it apart. Here’s how it compares to other leading models based on its core strengths:
