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

🚧 Code coming soon. Stay tuned!

Introduction

We present Agent Banana, a agentic planner–executor framework designed for high-fidelity, object-aware, thinking with editing. Agent Banana offers these key features:

• 🔥 Framework: Agent Banana couples high-level reasoning with tool-use capabilities to decompose complex requests into atomic sub-edits. It employs "Photoshop-style" layer isolation and masking to ensure precise modifications while preserving non-target content.

• 🔥 Context Folding: To enable stable long-horizon control, we introduce Context Folding, which compresses long interaction histories into structured memory. This allows the system to track state changes effectively and support rollback/replanning across multi-turn interactions.

• 🔥 Image Layer Decomposition: We propose Image Layer Decomposition to perform edits on isolated high-resolution layers. This approach prevents drift across iterations and ensures that edits are applied at native resolution without downsampling artifacts.

• 🔥 HDD-Bench: We release HDD-Bench, a high-definition, dialogue-based benchmark featuring verifiable stepwise targets and native 4K images. Unlike prior single-turn benchmarks, it supports rigorous diagnosis of long-horizon failures and professional workflow simulation.

• 🔥 Performance: On HDD-Bench, Agent Banana achieves state-of-the-art results in multi-turn consistency and background fidelity (e.g., IC 0.871, SSIM 0.84) while remaining competitive on instruction following.
