Agent Banana: High-Fidelity Image Editing with Agentic Thinking and Tooling

Researchers introduced Agent Banana, a hierarchical AI agent for high-fidelity, multi-turn image editing. It tackles persistent issues like models over-editing content and failing on long, complex workflows. The system uses 'Context Folding' for memory and 'Layer Decomposition' for localized edits, achieving 0.871 multi-turn consistency and strong background fidelity on the new 4K HDD-Bench. It outperforms existing methods by preserving object faithfulness across professional-grade, ultra-high-definition editing tasks.
