Producing publication-ready illustrations is a labor-intensive bottleneck within the analysis workflow. Whereas AI scientists can now deal with literature critiques and code, they wrestle to visually talk advanced discoveries. A analysis staff from Google and Peking College introduce new framework referred to as ‘PaperBanana‘ which is altering that through the use of a multi-agent system to automate high-quality educational diagrams and plots.

5 Specialised Brokers: The Structure
PaperBanana doesn’t depend on a single immediate. It orchestrates a collaborative staff of 5 brokers to remodel uncooked textual content into skilled visuals.


Section 1: Linear Planning
- Retriever Agent: Identifies the 10 most related reference examples from a database to information the type and construction.
- Planner Agent: Interprets technical methodology textual content into an in depth textual description of the goal determine.
- Stylist Agent: Acts as a design guide to make sure the output matches the “NeurIPS Look” utilizing particular shade palettes and layouts.
Section 2: Iterative Refinement
- Visualizer Agent: Transforms the outline into a visible output. For diagrams, it makes use of picture fashions like Nano-Banana-Professional. For statistical plots, it writes executable Python Matplotlib code.
- Critic Agent: Inspects the generated picture towards the supply textual content to seek out factual errors or visible glitches. It gives suggestions for 3 rounds of refinement.
Beating the NeurIPS 2025 Benchmark


The analysis staff launched PaperBananaBench, a dataset of 292 check instances curated from precise NeurIPS 2025 publications. Utilizing a VLM-as-a-Decide method, they in contrast PaperBanana towards main baselines.
| Metric | Enchancment over Baseline |
| General Rating | +17.0% |
| Conciseness | +37.2% |
| Readability | +12.9% |
| Aesthetics | +6.6% |
| Faithfulness | +2.8% |
The system excels in ‘Agent & Reasoning’ diagrams, reaching a 69.9% general rating. It additionally gives an automatic ‘Aesthetic Guideline’ that favors ‘Comfortable Tech Pastels’ over harsh major colours.
Statistical Plots: Code vs. Picture
Statistical plots require numerical precision that normal picture fashions usually lack. PaperBanana solves this by having the Visualizer Agent write code as a substitute of drawing pixels.
- Picture Technology: Excels in aesthetics however usually suffers from ‘numerical hallucinations’ or repeated components.
- Code-Based mostly Technology: Ensures 100% information constancy through the use of the Matplotlib library to render the ultimate plot.
Area-Particular Aesthetic Preferences in AI Analysis
In accordance with the PaperBanana type information, aesthetic selections usually shift based mostly on the analysis area to match the expectations of various scholarly communities.
| Analysis Area | Visible ‘Vibe‘ | Key Design Parts |
| Agent & Reasoning | Illustrative, Narrative, “Pleasant” | 2D vector robots, human avatars, emojis, and “Consumer Interface” aesthetics (chat bubbles, doc icons) |
| Pc Imaginative and prescient & 3D | Spatial, Dense, Geometric | Digicam cones (frustums), ray strains, level clouds, and RGB shade coding for axis correspondence |
| Generative & Studying | Modular, Movement-oriented | 3D cuboids for tensors, matrix grids, and “Zone” methods utilizing mild pastel fills to group logic |
| Idea & Optimization | Minimalist, Summary, “Textbook” | Graph nodes (circles), manifolds (planes), and a restrained grayscale palette with single spotlight colours |
Comparability of Visualization Paradigms
For statistical plots, the framework highlights a transparent trade-off between utilizing a picture technology mannequin (IMG) versus executable code (Coding).
| Characteristic | Plots through Picture Technology (IMG) | Plots through Coding (Matplotlib) |
| Aesthetics | Typically larger; plots look extra “visually interesting” | Skilled and normal educational look |
| Constancy | Decrease; susceptible to “numerical hallucinations” or ingredient repetition | 100% correct; strictly represents the uncooked information offered |
| Readability | Excessive for sparse information however struggles with advanced datasets | Constantly excessive; handles dense or multi-series information with out error |
Key Takeaways
- Multi-Agent Collaborative Framework: PaperBanana is a reference-driven system that orchestrates 5 specialised brokers—Retriever, Planner, Stylist, Visualizer, and Critic—to remodel uncooked technical textual content and captions into publication-quality methodology diagrams and statistical plots.
- Twin-Section Technology Course of: The workflow consists of a Linear Planning Section to retrieve reference examples and set aesthetic pointers, adopted by a 3-round Iterative Refinement Loop the place the Critic agent identifies errors and the Visualizer agent regenerates the picture for larger accuracy.
- Superior Efficiency on PaperBananaBench: Evaluated towards 292 check instances from NeurIPS 2025, the framework outperformed vanilla baselines in General Rating (+17.0%), Conciseness (+37.2%), Readability (+12.9%), and Aesthetics (+6.6%).
- Precision-Centered Statistical Plots: For statistical information, the system switches from direct picture technology to executable Python Matplotlib code; this hybrid method ensures numerical precision and eliminates “hallucinations” frequent in normal AI picture mills.
