Tencent's ContextPilot: Agent Manages Context with Credit Assignment
omarsar0 · x · 2026-09-01
Tencent introduces ContextPilot to address unbounded context growth in long-horizon tasks. The framework enables agents to edit their working context using global planning, long-term memory, and adaptive soft compression to offload information rather than discard it.
The key innovation lies in training via credit assignment. Instead of equally distributing the final reward to all intermediate edits (standard RL), ContextPilot uses context and entropy variation to identify which edits actually mattered, sampling branches at those points to optimize memory management more precisely.
