TokenPilot: Stabilizing context for efficient LLM inference.

The escalating computational cost of LLM agents operating in long-horizon sessions presents a significant bottleneck. As context accumulates, inference expenses surge, prompting existing solutions to resort to text pruning or dynamic memory eviction. However, these methods often disrupt sequence continuity, leading to prefix mismatches and cache invalidation. This paper introduces TokenPilot, a novel dual-granularity context management framework designed to navigate this inherent trade-off between text sparsity and prompt cache integrity.

Ingestion-Aware Compaction: Stabilizing the LLM Foundation

TokenPilot tackles context management at two critical levels. Globally, its Ingestion-Aware Compaction mechanism acts as a robust harness. It stabilizes prompt prefixes by acting at the ingestion gate, effectively filtering out open-world environmental noise before it can inflate the context window. This ensures a consistent and reliable starting point for agent interactions.

Lifecycle-Aware Eviction: Maximizing Contextual Utility

Locally, the framework employs Lifecycle-Aware Eviction. This component intelligently monitors the residual utility of context segments, ensuring content is offloaded only when its task relevance has demonstrably expired. By enforcing a conservative batch-turn schedule, TokenPilot avoids premature discarding of valuable information, thereby maintaining prompt cache continuity and enhancing overall agent performance.

Quantifiable Efficiency Gains in Long-Horizon Tasks

Experiments conducted on the PinchBench and Claw-Eval benchmarks, across both isolated and continuous modes, underscore the efficacy of TokenPilot. In isolated mode, the system achieved cost reductions of 61% and 56%. Under continuous mode, which better simulates real-world long-horizon deployments, these savings jumped to 61% and an impressive 87%, all while preserving competitive performance levels against existing systems. This demonstrates the significant economic and operational advantages of the TokenPilot LLM context management approach.
