Dev teams replace raw chat history with Hindsight for LLM agents

Two development teams have detailed their experiences building LLM agents for customer support and sales intelligence, both encountering significant issues with traditional chat history management. They found that simply appending raw chat logs led to increased latency, higher token costs, and context window contamination, causing agents to mix up information or lose critical details. Both teams successfully transitioned to a structured memory architecture using Hindsight, which separates long-term semantic memory into distinct, queryable banks for individual and global resolutions, thereby improving agent performance and reliability.
