Try WaveSpeedAI FLUX Kontext Dev Ultra Fast for FREEIntroducing FLUX.1 Kontext Dev Ultra-Fast: Lightning-Speed Image Editing Has Arrived on WaveSpeedAI
The era of waiting for AI image edits is over. WaveSpeedAI is thrilled to announce the availability of FLUX.1 Kontext Dev Ultra-Fast, a groundbreaking image-to-image model that combines state-of-the-art editing capabilities with unprecedented inference speeds. Built on Black Forest Labs’ revolutionary 12 billion parameter architecture, this model delivers professional-grade image transformations in seconds—not minutes.
Whether you’re refining product photography, creating character variations, or implementing precise visual edits, FLUX.1 Kontext Dev Ultra-Fast represents a quantum leap in what’s possible with AI-powered image editing.
What is FLUX.1 Kontext Dev Ultra-Fast?
FLUX.1 Kontext Dev Ultra-Fast is an optimized version of Black Forest Labs’ FLUX.1 Kontext [dev], a rectified flow transformer specifically designed for in-context image generation and editing. Unlike traditional text-to-image models, Kontext performs in-context image generation, allowing you to prompt with both text and images simultaneously, extracting and modifying visual concepts to produce coherent, high-quality results.
The model was developed using guidance distillation training techniques, making it significantly more efficient than comparable solutions. At its core, it’s a 12 billion parameter powerhouse that can run editing operations up to 8x faster than leading competitors like GPT-Image, while delivering results that match or exceed proprietary alternatives.
Black Forest Labs introduced the Kontext family to address a critical gap in the market: until recently, all capable generative image editing models were locked behind proprietary platforms. FLUX.1 Kontext [dev] changed that paradigm by delivering proprietary-level performance in an open-weights model—and WaveSpeedAI’s ultra-fast implementation takes this accessibility even further.

Real-World Use Cases
E-Commerce and Product Photography
Transform product images for different campaigns, seasons, or target markets. Change backgrounds, adjust lighting conditions, or place products in lifestyle contexts—all without expensive photo shoots. A single product image can spawn dozens of variations in minutes.
Creative Agencies and Design Studios
Rapidly iterate on visual concepts with clients. Instead of lengthy revision cycles, generate variations in real-time during meetings. Test different color schemes, compositions, and styles before committing to final artwork.
Game Development and Character Design
Maintain character consistency across promotional materials, in-game assets, and marketing collateral. Generate characters in different poses, environments, and situations while preserving their distinctive visual identity.
Social Media Content Creation
Keep visual branding consistent across posts while adapting content for different platforms, campaigns, or trends. Create seasonal variations of evergreen content without starting from scratch.
Architectural Visualization
Modify interior designs, change materials, adjust lighting conditions, or add seasonal elements to property renders. Help clients visualize alternatives without regenerating entire scenes.
Fashion and Apparel
Visualize garments in different colors, patterns, or fabrics. Create lookbooks by placing items on various model types or in different settings. Test designs before committing to physical samples.
