There A new large-scale dataset from Apple aims to advance the development of text-guided editing models for images. The data set, dubbed Pico-Banana-400K, contains 400,000 real images coupled with artificially introduced edited versions, so researchers can train more effective and context-aware image-editing systems. It is distributed as open-source under a research-only licence, thus inaccessible for commercial applications.
A Dataset Designed for Real-World Editing Tasks
The paper, called “Pico-Banana-400K: A Large-Scale Dataset for Text-Guided Image Editing”, shows how Apple went about building a more comprehensive and real-world training set, as arXiv notes. The dataset is derived from OpenImages and contains 35 different edits. They are organised in single and multi-turn requests and preference pairs — aligning better with the types of requests users make.

This architecture facilitates that the dataset is not merely synthetic or overcurated, but rather it promotes real-world end-to-end editing techniques. That means both successful and negative edit results, which are essential for building a model that stays on script — teaching AI not just how to edit, but also how to pick higher-quality options.
How Pico-Banana-400K Was Built
Apple created the edited photo pairs by combining a generative model (named Nano Banana) and another multimodal system serving as an automated judge. In the event of a rejection, output had to be regenerated until it was not rejected. The images cover a variety of photographic settings (e.g., human-orientated, text-heavy), thus facilitating nuanced model learning.
The dataset also brings to light what’s still challenging in AI systems (text replacement or spatial placement of objects in images, for example), giving researchers more insight into why the state of the art may be falling short.
A Strategic Move Amid Apple’s Slow AI Rollout
The timing is interesting, given the continued spotlight on Apple's AI ecosystem, which could be being pillaged here. Although the company has increased Apple Intelligence capabilities in the newest iPhones, that long overdue Siri refresh — announced back in 2024 — is still yet to materialise.

One-eyed by releasing Pico-Banana-400K: This measure may allow Apple to enhance its position in the burgeoning AI research community, even if it hasn’t formally shown how its long-term AI plans work.
Availability
Pico-Banana-400K is available now via GitHub for academic and research development and provides a new tool for AI researchers to train next-gen image editing models.
