Context window management
What is Context window management?
Context window management refers to techniques and tools for making better use of the limited memory available to AI models during conversations—compressing information, tracking what the model sees, and caching repeated content to fit more interactions into the same space without losing capability.
As AI agents tackle longer tasks and handle more complex interactions, managing context efficiently directly impacts both operating costs and the quality of work the model can do, making this a practical lever for improving agent performance at scale.
