FLUX.1 Kontext [max] ‍ FLUX.1 Kontext [pro] Try now in Playground Contact us for Enterprise ‍ Get notified

Starting today on Together AI, you can access FLUX.1 Kontext [max] and FLUX.1 Kontext [pro] from Black Forest Labs (BFL), a suite of generative flow matching models that allow you to generate and edit images through in-context image generation. Unlike existing text-to-image models, FLUX.1 Kontext allows you to prompt with both text and images, and seamlessly extract and modify visual concepts to produce new, coherent renderings. TL;DR: FLUX.1 Kontext [max] and [pro] now available on Together AI: In-context image generation combining text and images FLUX.1 Kontext [dev] coming soon (currently in private beta at BFL) Character consistency, local editing, style reference, and interactive speed Iterative editing capabilities for step-by-step refinement

What's New? We're launching support for the FLUX.1 Kontext family, a suite of generative flow matching models for in-context image generation and editing. FLUX.1 Kontext [max] : Maximum performance at high speed Try now → Experimental model with greatly improved prompt adherence and typography generation Premium consistency for editing without compromising on speed Available now on Together AI

FLUX.1 Kontext [pro] : Pioneer for fast, iterative image editing Try now → Single model delivering local editing, generative in-context modifications and text-to-image generation Handles both text and reference images as inputs for targeted edits Operating up to an order of magnitude faster than previous state-of-the-art models Available now on Together AI

FLUX.1 Kontext [dev] : Open weights model - Coming Soon Lightweight 12B diffusion transformer suitable for customization Currently in private beta at Black Forest Labs for research usage and safety testing Will be available on Together AI upon public release Compatible with previous FLUX.1 [dev] inference code

Your Images. Your Words. Your World. FLUX.1 Kontext goes beyond traditional text-to-image by enabling you to modify input images via simple text instructions - no need for fine-tuning or complex editing workflows. How FLUX.1 Kontext Works FLUX.1 Kontext marks a significant expansion of classic text-to-image models by unifying instant text-based image editing and text-to-image generation. As a multimodal flow model, it combines character consistency, context understanding and local editing capabilities with leading text-to-image synthesis. Play. Create. Manipulate... Iterate. Character Consistency Preserve unique elements of an image, such as a reference character or object in a picture, across multiple scenes and environments. Starting from a single reference photo, you can place the same person in different scenarios while maintaining identity.

Local Editing Make targeted modifications of specific elements in an image without affecting the rest. Whether changing colors, adding objects, or altering backgrounds, Kontext applies changes while maintaining the overall composition. Style Transfer Generate novel scenes while preserving unique styles from a reference image, directed by text prompts. Transform images into different artistic styles while keeping important visual elements intact.

Interactive Speed & Iterative Editing Iterate at minimal latency for both image generation and editing. FLUX.1 Kontext allows you to iteratively add more instructions and build on previous edits, refining your creation step-by-step while preserving image quality and character consistency. Text Editing Edit text within images for updating marketing materials, signage, product labels, and social media content. Use simple quoted prompts like "Replace ‘JOY’ with 'BFL'" while maintaining the original font style and layout.

Getting Started with FLUX.1 Kontext Try Kontext today in our playground or connect via our APIs: ‍ FLUX.1 Kontext [max]: Available now on Together AI FLUX.1 Kontext [pro]: Available now on Together AI FLUX.1 Kontext [dev]: Coming soon (currently in private beta at BFL)

Compatible with existing Together AI workflows. Use our Python SDK to quickly integrate Kontext into your applications:

from together import Together

client = Together()

imageCompletion = client.images.generate( model="black-forest-labs/FLUX.1-kontext-pro", prompt="make the bird red and the background a desert", image_url="https://cdn.sanity.io/images/gsvmb6gz/production/373431a80014dad2e2614b4e1b8936ff8753e62d-832x1248.png?fm=webp", )

print(imageCompletion.data[0].url)
