Paper Banana: AI Multi-Agent System for Publication-Quality Diagrams. Unlike single-model approaches, Paper Banana uses 5 specialized AI agents working together to create, critique, and refine technical diagrams with stunning accuracy. How It Works: PaperBanana implements a two-phase multi-agent pipeline with 5 specialized agents: - Phase 1 -- Linear Planning: - Retriever selects the most relevant reference examples from a curated set of 13 methodology diagrams spanning agent/reasoning, vision/perception, generative/learning, and science/applications domains -Planner generates a detailed textual description of the target diagram via in-context learning from the retrieved examples -Stylist refines the description for visual aesthetics using NeurIPS-style guidelines (color palette, layout, typography) - Phase 2 -- Iterative Refinement (3 rounds): Visualizer renders the description into an image (Gemini 3 Pro for diagrams, Matplotlib code for plots) Critic evaluates the generated image against the source context and provides a revised description addressing any issues - Steps 4-5 repeat for up to 3 iterations Open source ❤️ implementation and extension of Google Research’s PaperBanana ***Official code coming soon...
