PEEK: Context Map as an Orientation Cache for Long-Context LLM Agents
The paper introduces PEEK, a system designed to enhance long-context LLM agents by maintaining reusable orientation knowledge. This context map allows agents to interact with recurring external contexts more effectively and efficiently. PEEK demonstrates significant improvements in performance metrics compared to existing frameworks.
- ▪PEEK caches and maintains orientation knowledge as a context map, which is a small artifact in the agent's prompt.
- ▪The system improves long-context reasoning and information aggregation by 6.3-34.0% while using fewer iterations and incurring lower costs.
- ▪PEEK also enhances context learning, increasing solving rates and rubric accuracy by 6.0-14.0% and 7.8-12.1%, respectively.

Across invocations, existing approaches preserve either the agent's trajectory, passive access to raw material, or task-level strategies.
