Kontext Bench

Kontext Bench is a benchmark for image editing models consisting of source images paired with image editing instructions and category tags.

The benchmark comprises 1026 unique image-prompt pairs derived from 108 base images from diverse sources. It spans five core tasks: local instruction editing, global instruction editing, text editing, style reference, and character reference. We found that the scale of the benchmark provides a good balance between reliable human evaluation and comprehensive coverage of real-world applications.

Fields

Each line in metadata.jsonl consists of

file_name: Path to the image file relative to the split directory
instruction: The editing instruction to apply to the image
category: Category of the editing instruction
key: Unique identifier for this image-instruction pair
image_idx: Index of the source image
prompt_idx: Index of the prompt for this image

An example entry is shown below:
