Features of FLUX Kontext
Instant In-Context Image Editing
With FLUX Kontext, edit images using both text prompts and reference images. FLUX.1 Kontext Pro allows you to perform precise, local edits—modify specific objects, adjust environments, or change styles—without impacting the rest of your image. Experience context-aware modifications and seamless blending powered by FLUX Kontext technology.
Step-by-Step Iterative Creation
FLUX.1 Kontext Pro empowers users to iteratively refine their images—add new instructions, build on previous edits, and maintain character consistency across every change. FLUX Kontext's rapid feedback and multimodal understanding enable stepwise creation and experimentation, making it the perfect tool for ideation, conceptual design, and prototyping.
Unmatched Speed & Quality
FLUX.1 Kontext Pro is optimized for high-speed image generation and editing, outperforming competing models in latency while delivering state-of-the-art quality. With FLUX Kontext, you get top-tier text-to-image synthesis, accurate prompt following, photorealistic rendering, and reliable typography—all at speeds up to 8x faster than other leading models.

Frequently Asked Questions
What is Flux Kontext and what can it do?
Flux Kontext is an AI model for image-to-image generation and editing. It lets you modify existing images with text prompts, change styles, swap objects, or even edit text directly inside the image. You can use it to remaster images, apply art styles, or transform subjects while preserving context, layout, and character identity.
How does Flux Kontext work with image editing?
Flux.1 Kontext uses both an image and a text prompt to understand the visual context and perform edits. It can change specific objects, modify backgrounds, alter text, or even restyle the whole image—without affecting unrelated areas. The model understands local details and lets you make multiple edits step by step.
Does Flux Kontext support consistent characters across edits?
Yes, Flux Kontext preserves character identity, clothing, and style across different scenes and edits. If you want consistency, describe the subject clearly and say what should stay the same. This allows you to evolve a character while keeping them recognizable throughout.
What are FLUX Kontext’s Key Performance Benchmarks?
FLUX.1 Kontext is exceptionally fast: around 3.2 seconds for 1024x1024 text-to-image and 3.8 seconds for image-to-image edits. This is 8x faster than GPT-Image and significantly quicker than previous models. On the specialized KontextBench, it ranks top in text editing and local editing, and leads in character preservation. It performs excellently across all context image generation tasks and shows strong overall quality in aesthetics, prompt following, text generation, and realism.
What makes Flux Kontext different from other image generators?
Flux Kontext stands out with its ability to handle both text-to-image and in-context image edits. It supports consistent character tracking, localized changes, fast iteration, and strong style preservation—all while delivering competitive speed and accuracy compared to leading models.
What’s the best way to write prompts for Flux Kontext?
With Flux.1 Kontext, clarity is key. Use specific descriptions like colors, styles, or actions. Say exactly what to change and what to keep. For best results, write in steps, name visual elements directly, and avoid vague terms like "make it better." This helps the model follow your intent closely.
What’s the Difference Between FLUX Kontext [Pro] and [Max]?
The FLUX Kontext suite includes two models:
- FLUX.1 Kontext Pro: Focuses on fast iterative image editing workflows, excelling in text editing, local editing, and character preservation. It’s designed for production use.
- FLUX.1 Kontext Max: An experimental model for maximum performance, significantly improving prompt adherence and text generation. It leads in global editing and style reference. Max offers premium rendering quality without speed compromise for higher-end, experimental applications.
Crucially, FLUX.1 Kontext Pro (an image editing suite, May 29, 2025) is distinct from FLUX 1.1 Pro (a text-to-image model, October 2, 2024).
API Considerations for FLUX Kontext Integration?
FLUX Kontext is primarily accessible via API, available through Black Forest Labs’ API (endpoint: black-forest-labs/FLUX.1-kontext-pro). An open-source version isn’t released yet. The API accepts both text prompts and reference image URLs (Base64 data URIs or hosted file URLs) as input.
