Academic research often depends on clear diagrams, methodology figures, and statistical illustrations to communicate complex ideas. However, creating publication-quality figures can be time-consuming and usually requires both technical understanding and design skills.
PaperBanana is an agentic framework proposed to automate this part of the research workflow. The system uses vision-language models and image-generation models to create academic illustrations from research content, with the goal of producing figures that are accurate, readable, concise, and visually suitable for scientific publications.

The Need for Automated Academic Illustration
Research papers frequently contain complex methodologies, architectures, workflows, and experimental results. Converting these concepts into clear illustrations requires considerable manual effort.
For AI researchers in particular, the growing speed of research makes automated assistance for scientific communication increasingly valuable. PaperBanana addresses this problem by treating illustration generation as a structured research task rather than simply generating an image from a text prompt.
PaperBanana Framework
PaperBanana uses multiple specialized agents to coordinate different stages of illustration creation.
The framework involves processes for:
- Retrieving relevant references
- Planning the content of an illustration
- Planning visual style
- Generating the illustration
- Reviewing the generated result
- Refining the output through self-critique
This agentic structure allows different stages of the generation process to work together rather than relying on a single image-generation step.
Reference Retrieval
Reference retrieval helps the system understand how academic illustrations should represent particular concepts.
By using relevant research material as a reference, the framework can better align generated figures with the information and visual conventions associated with scientific communication.
This is particularly important for methodology diagrams, where preserving the relationship between components is more important than simply producing an attractive image.
Content and Style Planning
PaperBanana separates the planning of what should be shown from how it should look.
Content planning focuses on representing the important ideas and relationships from the research material. Style planning focuses on the visual organization and presentation of those ideas.
This separation helps create illustrations that are both informative and visually structured.
Iterative Self-Critique
A major component of the framework is iterative refinement.
Instead of accepting the first generated illustration, PaperBanana uses a self-critique process to evaluate the output and improve it.
This approach is important because academic illustrations need more than visual quality. They must also preserve the meaning of the research and communicate information clearly.
PaperBananaBench
The researchers introduce PaperBananaBench, an evaluation benchmark containing 292 methodology-diagram test cases derived from NeurIPS 2025 publications.
The benchmark covers different research domains and illustration styles, providing a way to evaluate automated academic illustration systems systematically.
Evaluation Criteria
PaperBanana evaluates generated illustrations across several important dimensions, including:
Faithfulness
The illustration should accurately represent the information and methodology being communicated.
Conciseness
The figure should communicate the important information without unnecessary complexity.
Readability
Labels, components, and relationships should be understandable to the viewer.
Aesthetics
The final illustration should have a professional and visually coherent appearance suitable for academic communication.
According to the paper, PaperBanana outperforms the evaluated baseline methods across these dimensions.
Statistical Plot Generation
The framework is not limited to methodology diagrams. The researchers also show that the approach can be extended to generate high-quality statistical plots.
This suggests that automated scientific illustration could potentially support multiple stages of research communication, from explaining methodologies to presenting experimental findings.
Importance for AI Research
PaperBanana highlights a broader direction in AI research: AI systems that assist not only with scientific discovery but also with scientific communication.
As autonomous and semi-autonomous AI scientists become more capable, automatically producing understandable figures can reduce the manual effort required to communicate research results.
Future of AI-Assisted Research
The idea behind PaperBanana represents a shift toward more complete AI research workflows. Instead of AI systems focusing only on writing, coding, or experimentation, future systems may also assist with visual explanation, documentation, presentation, and publication preparation.
This can make scientific workflows more efficient while allowing researchers to spend more time on ideas, experimentation, and interpretation.

Conclusion
PaperBanana presents an agentic approach to automating academic illustration using vision-language and image-generation models. Its workflow combines reference retrieval, content planning, style planning, image generation, and iterative self-critique to produce publication-oriented illustrations.
The introduction of PaperBananaBench also provides a structured way to evaluate the quality of automatically generated academic figures. Overall, the work demonstrates how AI can move beyond generating text and code toward automating visual scientific communication, an important direction for the future of AI-assisted research.
