LangChain

LangChain provides a comprehensive platform for the entire agent engineering lifecycle, helping you ship reliable AI agents to production. It offers full visibility and control over every step of your agent's process, allowing for rapid iteration through the build, test, and deploy cycle. The infrastructure is designed for durable performance, handling long-running workloads and human oversight at scale, while remaining model-neutral to prevent vendor lock-in.

The platform includes several key components:

• Open Source Frameworks: Use the main LangChain framework to ship quickly with pre-built agent architecture, or use LangGraph for low-level primitives to build custom agent workflows.
• LangSmith Agent Engineering Platform: This tool provides deep visibility into agent behavior through tracing, helps improve quality with robust evaluation tools, and offers deployment infrastructure built for memory management and auto-scaling.
