CliffCompaction is an autocompaction technique designed to reduce the cost of long-horizon coding agents by up to 50% while maintaining or improving performance. It efficiently manages limited context windows, achieving state-of-the-art results on Terminal-Bench and enhancing test-time scaling.

AI-assisted summary based on the listed source.

Agents often work on complex problems that require millions of tokens of context, which necessitates compacting across sessions due to limited context windows. We develop CliffCompaction, an autocompaction technique that reduces cost by up to 50% under a bounded context while maintaining or improving performance...

This technique addresses the challenge of limited context windows in AI coding agents working on complex, token-heavy problems, enabling more cost-effective and scalable solutions. Improved efficiency can accelerate development and deployment of advanced coding agents.
