### Abstract

Despite rapid advances in autonomous AI scientists powered by language models, generating publication-ready illustrations remains a labor-intensive bottleneck in the research workflow. To lift this burden, we introduce PaperBanana, an agentic framework for automated generation of publication-ready academic illustrations.

Powered by state-of-the-art VLMs and image generation models, PaperBanana orchestrates specialized agents to retrieve references, plan content and style, render images, and iteratively refine via self-critique. To rigorously evaluate our framework, we introduce **PaperBananaBench**, comprising **292 test cases** for methodology diagrams curated from NeurIPS 2025 publications.

## Multi-Agent Architecture

### Five Agents, One Mission

Each agent specializes in a critical stage of the illustration pipeline, working in concert to deliver publication-quality results.

#### 🔍 Retriever
Identifies relevant reference examples from academic databases to guide style and content alignment.

#### →

#### 📐 Planner
Translates scientific content into a detailed visual plan, decomposing structure and layout.

#### →

#### 🎨 Stylist
Enforces academic aesthetic standards — color palettes, typography, line weights, and visual hierarchy.

#### →

#### 🖼️ Visualizer
Renders the initial image or generates Python/Matplotlib plotting code from the visual plan.

#### →

#### 🔬 Critic
Performs iterative self-critique, inspecting generated results against source content and triggering refinement.

## Capabilities

### What PaperBanana Can Do

🗂️ NeurIPS-ready

#### Methodology Diagrams
Neural networks, flowcharts, multi-agent pipelines, and complex system architectures — all rendered to publication standards.

📊 Data-exact

#### Statistical Plots
Accurate data visualization via Matplotlib code generation. Bar charts, ablation studies, accuracy comparisons — zero hallucination guaranteed.

✏️ Sketch input

#### Sketch-to-Pro
Transform rough hand-drawn sketches into clean, harmonious academic figures with consistent fonts and styling.

✨ Polish mode

#### Aesthetic Refinement
Upload existing diagrams to upgrade fonts, colors, and spacing without altering underlying content or structure.

📚 Context-aware

#### Reference-Driven
Retrieves relevant papers to align style with academic conventions — your figures will match the venue aesthetic.

🔄 Auto-refine

#### Iterative Refinement
Self-critique loop ensures publication-quality output. The Critic agent reviews and forces regeneration until quality passes.

### PaperBananaBench

## How It Works

### From Text to Publication Figure in Seconds

Describe your methodology or paste your data. PaperBanana's agents collaborate to deliver a figure that passes peer review.

### STEP 01

✍️ Describe
Input your methodology, data, or sketch. PaperBanana accepts text, PDFs, or images.

### STEP 02

🔍 Retrieve
The Retriever agent scans reference databases to find style-aligned academic examples.

### STEP 03

📐 Plan & Style
Planner and Stylist agents create a detailed visual plan with academic-grade aesthetics.

### STEP 04

✨ Render & Refine
Visualizer renders the figure; Critic reviews and iterates until quality is publication-ready.
