The LangSmith platform

LangChain began in 2022 as a popular open-source project. It was designed to perform tasks that early large language models struggled with, including web searches, API calls and interactions with databases.

The company later focused on managing AI agents through its LangSmith platform. LangChain says that this product does not tie users to a specific model, cloud infrastructure or ecosystem. The company also states that LangSmith makes it possible to control agent behavior. According to the company, the platform has 7,000 customers, including Harvey, Rippling, Clay, NVIDIA, Toyota and Salesforce.
