Pico-Banana-400K: A Large-Scale Dataset for Text-Guided Image Editing (2510.19808v1)
Abstract: Recent advances in multimodal models have demonstrated remarkable text-guided image editing capabilities, with systems like GPT-4o and Nano-Banana setting new benchmarks. However, the research community's progress remains constrained by the absence of large-scale, high-quality, and openly accessible datasets built from real images. We introduce Pico-Banana-400K, a comprehensive 400K-image dataset for instruction-based image editing. Our dataset is constructed by leveraging Nano-Banana to generate diverse edit pairs from real photographs in the OpenImages collection. What distinguishes Pico-Banana-400K from previous synthetic datasets is our systematic approach to quality and diversity. We employ a fine-grained image editing taxonomy to ensure comprehensive coverage of edit types while maintaining precise content preservation and instruction faithfulness through MLLM-based quality scoring and careful curation. Beyond single turn editing, Pico-Banana-400K enables research into complex editing scenarios. The dataset includes three specialized subsets: (1) a 72K-example multi-turn collection for studying sequential editing, reasoning, and planning across consecutive modifications; (2) a 56K-example preference subset for alignment research and reward model training; and (3) paired long-short editing instructions for developing instruction rewriting and summarization capabilities. By providing this large-scale, high-quality, and task-rich resource, Pico-Banana-400K establishes a robust foundation for training and benchmarking the next generation of text-guided image editing models.
Summary
- The paper introduces Pico-Banana-400K, a large-scale dataset for text-guided image editing enhanced with dual-instruction formats and rigorous quality control.
- The dataset is structured into three subsets—SFT, preference pairs, and multi-turn sequences—covering 35 diverse editing types across various categories.
- Experimental results reveal high success for global photometric and stylistic edits, while highlighting challenges in precise spatial, symbolic, and human-centric modifications.
Pico-Banana-400K: A Comprehensive Resource for Text-Guided Image Editing
Introduction
Pico-Banana-400K introduces a large-scale, systematically curated dataset for text-guided image editing, addressing the limitations of prior resources in terms of scale, diversity, and quality control. The dataset is constructed from real photographs sourced from OpenImages, with edits generated by the Nano-Banana model and quality-filtered by Gemini-2.5-Pro. The design emphasizes comprehensive coverage of editing intents, rigorous automated and manual quality assurance, and support for both single-turn and complex multi-turn editing scenarios.

Dataset Construction and Taxonomy
The dataset comprises approximately 400K examples, organized into three primary subsets: single-turn supervised fine-tuning (SFT), preference pairs for alignment and reward modeling, and multi-turn editing sequences for compositional reasoning. Edits span 35 distinct types across eight major categories, including photometric, object-level semantic, scene composition, stylistic, text/symbolic, human-centric, scale, and spatial/layout operations. Each edit is executed by Nano-Banana and evaluated by Gemini-2.5-Pro using a weighted scoring system that prioritizes instruction compliance, seamlessness, preservation balance, and technical quality.

A dual-instruction format is provided for each example: a long, detailed prompt generated by Gemini-2.5-Flash for training, and a concise, user-style instruction rewritten by Qwen2.5-7B-Instruct, facilitating research on prompt granularity and natural user interaction.
Preference Data and Alignment
Failed editing attempts are automatically retried, and both successful and failed outputs are retained as preference pairs. This subset (56K examples) is critical for alignment research, enabling direct preference optimization (DPO) and reward modeling. Preference triplets consist of the original image, the instruction, and two outputs (success and failure), supporting robust model training and evaluation.

Multi-Turn Editing and Compositionality
The multi-turn subset (72K examples) extends single-turn edits into sequences of 2–5 consecutive modifications, with instructions generated to maintain discourse continuity and referential coherence. This design supports research into iterative refinement, context-aware editing, and planning across temporally ordered edit chains.

Dataset Analysis and Edit Success Rates
Quantitative analysis reveals strong performance for global photometric and stylistic edits, with success rates exceeding 0.90 for style transfer and film grain effects. Object-level semantic edits and scene composition operations achieve moderate reliability (0.80–0.83), while fine-grained spatial manipulations, outpainting, and text operations remain challenging (success rates as low as 0.57). Human-centric stylizations, especially those requiring identity preservation under large shape or style changes, also exhibit lower reliability.
Figure 5: Per–edit type success rates, highlighting the relative difficulty of spatial, symbolic, and human-centric edits.
These results indicate that current editing models excel at global transformations but struggle with precise geometry, layout extrapolation, and symbolic fidelity. The dataset’s fine-grained taxonomy and failure cases provide a valuable foundation for targeted improvements in spatial conditioning, geometry-aware objectives, and explicit text rendering supervision.
Comparison to Prior Work
Pico-Banana-400K distinguishes itself from previous datasets by its scale, real-image provenance, comprehensive edit taxonomy, and rigorous quality control. Unlike synthetic-only corpora or limited human-annotated sets, it offers both breadth and depth, including multi-turn and preference data for advanced alignment and compositionality research. The dataset is fully shareable under clear licensing, supporting open research and benchmarking.
Practical and Theoretical Implications
Practically, Pico-Banana-400K enables the training of instruction-faithful, robust image editing models capable of handling diverse real-world editing intents. The inclusion of multi-turn and preference subsets supports research into iterative editing, reward modeling, and alignment techniques such as DPO. Theoretically, the dataset facilitates studies on prompt granularity, compositional reasoning, and the limitations of current MLLM-based editing systems, especially in spatial and symbolic domains.
Future developments may focus on integrating region-referential prompting, geometry-aware training, and OCR-informed losses to address the identified challenges. The dataset’s structure also supports benchmarking and ablation studies on controllability, visual fidelity, and instruction following.
Conclusion
Pico-Banana-400K establishes a new standard for text-guided image editing datasets, combining scale, diversity, and quality. Its systematic construction, dual-instruction format, and specialized subsets provide a robust foundation for advancing both practical model development and theoretical research in multimodal editing. The resource is publicly available, enabling broad adoption and further innovation in the field.

Pico-Banana-400K: A big, high-quality dataset for teaching AI to edit images with words
Overview
This paper introduces Pico-Banana-400K, a huge collection of about 400,000 examples that teach AI how to edit real photos using simple text instructions. Think of it like a giant practice workbook for an AI photo editor: each example shows a real picture, a written instruction (like “make the sky look like sunset” or “add a hat to the cat”), and the edited result. The goal is to help researchers build better, safer, and more accurate image-editing AIs.
Key objectives and questions
The authors set out to:
- Build a large, shareable dataset from real photos (not just AI-generated images).
- Cover many different kinds of edits (colors, adding/removing objects, styles, text changes, people edits, zooming, and expanding the scene).
- Make sure the edits are high quality and truly follow the instructions.
- Support different research tasks: single edits, multi-step edits, and “which edit is better?” preference training.
In simple terms, they ask: Can we create a big, trustworthy set of before-and-after examples that helps AI follow editing instructions well? What kinds of edits are easy or hard for current models? And how can we automatically check quality without needing a human for every image?
How they built the dataset (methods)
The team used a step-by-step pipeline, like an assembly line:
- Start with real photos from OpenImages, a public collection.
- Organize edits into a “taxonomy,” which is a careful list of 35 edit types grouped by category. For example: change overall color tone, add/remove an object, replace a background, switch seasons, apply an art style, edit text on signs, adjust a person’s expression, zoom in, or extend the edges of a photo.
- Create two versions of instructions for each edit:
- Long, detailed instructions that are extra clear for training.
- Short, user-style instructions that sound like how people normally talk.
- Use an editing model (called Nano-Banana) to carry out the instructions on the image.
- Use another model (Gemini) as an “automatic judge” to score the result on four things:
- Instruction compliance: did it follow the request?
- Seamlessness: does the edit look natural, without weird artifacts?
- Preservation balance: did it keep the parts that shouldn’t change?
- Technical quality: is the image sharp, well-lit, and properly colored?
- If the edit fails, automatically try again. Keep both the good result and the failed one for “preference” training, where models learn which output is better.
- Build multi-turn sequences (2–5 step edit chains) to paper how models handle a series of related changes, like first adding a hat, then changing its color, then adjusting the lighting.
Think of the “judge” like a fair teacher grading homework. If the edit scores high enough, it’s kept in the dataset; if not, it’s marked as a failure and saved for training models to prefer better edits.
Main findings and why they matter
The dataset reveals which edits current AI models do well and which they struggle with:
- Easier edits: Big, global changes and style effects. For example, making an image look vintage, switching the overall color tone, or transforming the photo into an artist’s style. These succeed often (around 0.9 success rate for some).
- Medium difficulty: Object-level changes and scene tweaks. Removing or replacing an object or changing the season and weather usually work fairly well, but can sometimes affect nearby areas or drift slightly in color or texture.
- Hard edits: Precise geometry and text. Moving an object to a specific spot, changing its size or angle perfectly, or editing the exact font on a sign is tough. Text edits are especially brittle because letters must look clean, aligned, and readable in a realistic photo.
These insights matter because they point researchers toward the biggest challenges: fine spatial control, accurate layout changes, and clean text rendering. The dataset gives them the training material and the measurements to make progress on these tricky areas.
What this means for the future
Pico-Banana-400K is a strong foundation for building the next generation of text-guided image editors. It can help:
- Train models to follow instructions more faithfully and avoid breaking parts of the image that shouldn’t change.
- Align models using preference pairs (good vs. bad edits), so they learn what great edits look like.
- Teach models to plan multi-step edits and keep track of context across several changes.
- Bridge the gap between detailed training prompts and natural, human-style requests through its long and short instruction versions.
In the long run, this can lead to smarter, more reliable photo-editing tools that artists, students, and everyday users can trust—tools that make realistic changes, respect the original content, and understand what people want when they describe edits in plain language. The authors plan to use the dataset for model training and benchmarking, and they share it publicly to support open research and faster progress for everyone.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, focused list of what the paper leaves missing, uncertain, or unexplored.
- Reliance on proprietary models: The dataset generation (Nano-Banana), instruction authoring (Gemini-2.5-Flash/Pro), and automated judging (Gemini-2.5-Pro) depend on closed systems, leaving reproducibility with open-source tooling and the influence of vendor-specific biases unaddressed.
- Judge validity and calibration: No human ground-truth evaluation is reported to validate the automated judge’s scores or weights (40/25/20/15), nor any inter-rater agreement, calibration curves, or per–edit-type reliability analyses.
- Threshold sensitivity: The 0.7 quality cutoff is “empirically set,” but the paper does not examine how varying this threshold affects dataset composition, success rates, or downstream model performance.
- Human evaluation gap: There is no human-verified benchmark or audit (single- and multi-turn) to quantify instruction compliance, artifact types, preservation balance, typography fidelity, or identity preservation relative to the automated judge.
- Annotation richness: The dataset lacks spatial supervision (masks, bounding boxes, keypoints, click points/scribbles) and does not include region-level annotations for where edits occurred, limiting training of localization-aware editing models.
- Text edit ground truth: For text-related operations, there is no OCR transcript before/after, font metadata, bounding boxes, alignment/kerning metrics, or typography-specific labels to evaluate symbolic fidelity rigorously.
- Identity preservation signals: Human-centric edits have no identity-level annotations (face embeddings, landmarks, attributes) to measure identity drift or shading/geometry artifacts quantitatively.
- Multi-turn realism: Multi-turn sequences are created by randomly sampling additional edit types; the paper does not verify whether these sessions reflect real user workflows or measure discourse coherence/coreference resolution with human raters.
- Instruction diversity: Instructions appear to be English-only and are largely model-generated/summarized; there is no exploration of multilingual, noisy, ambiguous, or colloquial user prompts and their impact on training.
- Long vs short instructions: No ablations or training studies demonstrate how long (Gemini-authored) versus short (Qwen-summarized) instructions affect controllability, fidelity, generalization, or robustness.
- Preference data granularity: Preference pairs are binary (success vs failure) and sourced from retry attempts; there is no graded/ranked preference spectrum, taxonomy of failure types, or diversification beyond “failed until success,” which may bias negative samples.
- Per-criterion judge outputs: It is unclear whether per-criterion judge scores (instruction compliance, seamlessness, preservation, technical quality) are released; without them, reward modeling and error analysis are constrained.
- Dataset balance: The taxonomy is imbalanced across edit types (some with far fewer examples), but the effects of imbalance on training, generalization, and fairness are not studied.
- Hard-case retention: Examples that fail all three retries are discarded, potentially underrepresenting the hardest edits; the impact of excluding these cases on model robustness remains unknown.
- Domain coverage: Images are from OpenImages; generalization to other domains (e.g., medical, satellite, UI/screens, diagrams) and out-of-distribution settings is not evaluated.
- Safety and ethics: Human-centric edits (age/gender changes, caricatures, stylizations) raise questions about consent, identity misuse, demographic bias, and societal harms; the dataset lacks safety annotations, usage guidelines, or fairness audits.
- Typography challenges: The paper notes low success for typography edits but provides no specialized supervision (vector text overlays, font libraries, layout constraints) or benchmarks to address symbolic correctness.
- Spatial/layout conditioning: Difficult spatial operations (relocation, size/shape/orientation changes, outpainting) lack auxiliary conditioning signals (e.g., reference points, masks, depth/geometry priors); feasibility of adding such signals is not explored.
- Compositional single-turn edits: Each single-turn example is assigned one primary edit type; complex multi-constraint single-turn instructions (common in real use) are not represented or annotated.
- Artifact taxonomy: There is no systematic taxonomy or statistics of common artifacts (perspective breaks, boundary discontinuities, texture drift, color shifts) by edit type and content domain.
- Benchmarking baselines: The paper does not provide baseline models trained on Pico-Banana-400K or standardized evaluation suites to quantify gains over prior datasets on key axes (spatial accuracy, text fidelity, identity preservation).
- Versioning and provenance: Model versions, prompts, seeds, and configuration details (for Nano-Banana, Gemini variants) are not exhaustively documented, hindering precise replication and longitudinal comparisons.
- Resolution and canvas metadata: Image resolution/aspect changes (especially for zoom and outpainting) are not documented; lack of per-turn dimension metadata limits analysis of boundary continuity and scaling artifacts.
- Multi-turn state annotations: There are no intermediate state-change annotations (e.g., which regions were modified per turn, dependency graphs), making it hard to paper planning, coreference, and cumulative error.
- Impact on training dynamics: The dataset’s effects on training stability, sample efficiency, scaling laws, and compute cost trade-offs are not empirically assessed.
- Comparative quality: Although related datasets are listed, there is no quantitative side-by-side evaluation (human or automated) comparing Pico-Banana-400K’s instruction faithfulness, artifact rates, or diversity against alternatives.
