LangChain AI Agent & Prompt Orchestration

Build multi-step AI agent workflows and RAG knowledge systems using LangChain.

The Framework for Production AI Agents

LangChain is the leading developer framework for building applications with large language models. We use LangChain to orchestrate multi-step agent workflows — connecting LLMs to vector databases, SQL query engines, external APIs, and custom tools. Our LangChain implementations include structured output parsers, retry logic, and telemetry tracing via LangSmith. LangGraph extends LangChain's capabilities by introducing stateful graph architectures where agent nodes can branch, loop, and hand off to specialized sub-agents based on decision outputs — enabling complex multi-agent collaboration workflows. We instrument every LangChain deployment with LangSmith tracing, giving you visibility into exactly which prompts fired, what retrieval results were injected, and where latency occurs in each agent chain run. This observability is essential for diagnosing quality issues and optimizing prompt performance in production environments.

Common Use Cases

RAG Knowledge Bases

Autonomous search engines referencing local documents with source attribution.
