How LangChain Made Coding Agent Spend Predictable
LangSmith's LLM Gateway enables real-time cost management by setting budgets at various levels, providing visibility into spending, and allowing engineers to monitor and control agent usage without blocking productive work. The gateway integrates with platforms like Claude Code and LangChain Deep Agents, ensuring all eligible calls are tracked and analyzed alongside production data. It helps prevent accidental overuse and offers flexibility in managing spending, with internal testing revealing the importance of accurate cost accounting and real-time monitoring.
