LangSmith Fleet & Polly

Building an agent is easy. Managing 10,000 parallel agent sessions in production is hard. LangSmith Fleet is the industry standard for agent fleet management in 2026.

Fleet Management

Fleet provides a command center to monitor all active agents. You can:

  • View real-time state transitions of every active graph.
  • Interrupt long-running agents that are stuck in infinite loops.
  • Inject "Human-in-the-Loop" approvals directly from the dashboard.

AI-Assisted Debugging (Polly)

Polly is an AI-powered debugging assistant built into LangSmith. When an agent fails, Polly analyzes the execution trace, identifies the exact node where the context was lost or the tool schema failed, and proposes a fix for your graph logic.

💡 Key Insight: Enterprise SLAs require absolute visibility. You cannot deploy agents to production without tracing their thoughts, tool calls, and LLM latency. LangSmith Fleet is non-negotiable for enterprise deployments.
