  1. artificial intelligenceA technique used by AI agents to manage and reduce the size of accumulated conversation history or data during long-running tasks.

    The complex task sent the AI agent into a phenomenon called context compaction, which refers to a process that occurs in long-running AI agent sessions, leading to the model's context window becoming full. As a result, it ends up compressing the data so that it can continue running.
