What LangChain Said The Platform Does

LangChain said companies should be able to choose the best models for their needs, control their data and infrastructure, and continuously improve their agents while maintaining governance to operate securely at scale.

The company said LangSmith provides that foundation across three pillars: Agent Runtime, Agent Improvement, and Agent Governance.

Customers And Usage Examples

LangChain said more than 7,000 organizations already rely on LangSmith, including startups such as Harvey, Rippling, and Listen Labs and Fortune 500 companies such as NVIDIA, Toyota, and Salesforce.

According to LangChain, Clay uses LangSmith to monitor hundreds of millions of agent runs per month and improve its agents. The company also said Workday uses LangSmith to run and govern agents across the organization, reducing the time to deploy a new agent from five months to under a day.

Three Pillars Of LangSmith

LangChain said Deep Agents, LangGraph, and LangChain give developers flexibility across models and control over how context is managed. It also said its LLM and Tool Gateways help teams manage model budgets and fallbacks, protect sensitive data, and govern tool access and authentication across teams and agents.

The company said it will share several new LangSmith capabilities on Nov. 20 at a special release event.
