Multimodal
Generate and edit images through both text and image prompts. Flux.1 Kontext is a multimodal flow matching model that enables both text-to-image generation and in-context image editing. Modify images while maintaining character consistency and performing local edits up to 8x faster than other leading models. Model developer: Black Forest Labs Supported languages: English Model Release Date: June 30, 2025

Intended Use

Primary Use Cases

The model is intendended for broad commercial and research use. The model provides powerful text-to-image and image-editing capabalities:
  1. Change existing images based on an edit instruction.
  2. Have character, style and object reference without any finetuning.
  3. Robust consistency allows users to refine an image through multiple successive edits with minimal visual drift.
You can add more descriptions as needed.

Out-of-Scope Use Cases

Describe the use case that the model is not designed for.

Responsible AI Considerations

Black Forest Labs is committed to the responsible development of generative AI technology. Prior to releasing FLUX.1

Performance Evaluation

To validate the performance of our FLUX.1 Kontext models we conducted an extensive performance evaluation that we release in a tech report . Here we give a short summary: to evaluate our models, we compile KontextBench, a benchmark for text-to-image generation and image-to-image generation from crowd-sourced real-world use cases. The benchmark can be found here . In-Context Performance We show evaluation results across six in-context image generation tasks. FLUX.1 Kontext [pro] consistently ranks among the top performers across all tasks, achieving the highest scores in Text Editing and Character Preservation. We evaluate image-to-image models, including our FLUX.1 Kont
