Introducing FLUX.1 Kontext Dev Multi Ultra-Fast: Native Multi-Image Processing at Unprecedented Speed

The landscape of AI image editing has entered a new era. WaveSpeedAI is excited to announce the availability of FLUX.1 Kontext Dev Multi Ultra-Fast—an experimental endpoint that brings native multi-image handling to one of the most powerful image editing models available today. Whether you’re processing batch edits, creating multi-view compositions, or building complex visual workflows, this model delivers enterprise-grade performance without the wait.

What is FLUX.1 Kontext Dev Multi Ultra-Fast?

FLUX.1 Kontext is a 12 billion parameter rectified flow transformer developed by Black Forest Labs that has redefined what’s possible in AI-powered image editing. Unlike traditional text-to-image models, FLUX.1 Kontext performs in-context image generation—allowing you to prompt with both text and images simultaneously to seamlessly extract and modify visual concepts.

The Multi Ultra-Fast variant on WaveSpeedAI takes this foundation and optimizes it specifically for multi-image workflows. By concatenating image embeddings and text tokens into a unified sequence, the model processes multiple reference images in a single inference call, maintaining coherent style, pose, and lighting across all inputs.

This isn’t just incremental improvement—it’s a paradigm shift in how AI-driven image editing handles multiple visual inputs.

Key Features

Native Multi-Image Handling

Process multiple reference images simultaneously in a single API call
Maintain consistency across batch operations without manual intervention
Scale linearly with additional images—add three or four reference images with predictable performance trade-offs

Ultra-Fast Inference

Generate results in 3-5 seconds compared to 25-40 seconds for comparable models
Up to 8x faster than GPT-Image-1 and similar competitors
No cold starts—WaveSpeedAI’s infrastructure keeps models warm and ready

State-of-the-Art Consistency

Robust character and object preservation across multiple successive edits
Minimal visual drift during iterative refinement sessions
Outperforms existing open and closed models including Bytedance Bagel, HiDream-E1-Full, and Google’s Gemini-Flash Image

Unified Architecture

Single model handles both local editing and generative in-context tasks
Text manipulation capabilities for seamless in-image text changes
Style reference extraction for consistent visual language across scenes

Use Cases

Batch Product Photography

E-commerce teams can apply consistent edits across entire product catalogs. Change backgrounds, adjust lighting, or add branding elements to hundreds of product images while maintaining visual coherence. The multi-image handling ensures that edits applied to one image translate predictably across the entire batch.

Character-Consistent Content Creation

Content creators and marketing teams can generate multiple scenes featuring the same character or mascot. Feed reference images of your brand character, and the model preserves their identity across different environments, poses, and contexts—essential for maintaining brand consistency in campaigns.

Multi-View Asset Generation

Game developers and 3D artists can create consistent multi-view references from a single concept image. The model’s ability to understand spatial relationships helps generate turnaround views that maintain proportions and design details.

Style Transfer at Scale

Apply the unique aesthetic of a reference artwork across multiple target images. Whether you’re creating a unified visual style for a presentation, a social media campaign, or a video project, the model extracts and applies style characteristics consistently.

Iterative Design Workflows

Designers can refine compositions through multiple editing rounds without the visual degradation typical of other models. The model’s robust consistency allows for extensive iteration while preserving the core visual elements.

Getting Started with WaveSpeedAI

Accessing FLUX.1 Kontext Dev Multi Ultra-Fast through WaveSpeedAI is straightforward:

Sign up at WaveSpeedAI and obtain your API key
Explore the model at the model page
Integrate using our REST API with your preferred programming language

The API accepts multiple input images along with text prompts, returning processed results in seconds rather than minutes. With WaveSpeedAI’s infrastructure, you benefit from:

No cold starts: Models are always warm and ready for inference
Predictable pricing: Pay only for what you use with transparent per-image costs
Production-ready reliability: Built for integration into existing workflows and applications

Sample Workflow

A typical multi-image request might include:

Two or three reference images defining your desired style or character
A text prompt specifying the desired transformation
Optional parameters for resolution and output format

The model processes these inputs together, understanding the relationships between your references and applying your instructions coherently across the combined context.
