LangSmith is a platform to help developers close the gap between prototype and production. It’s designed for building and iterating on products that can harness the power–and wrangle the complexity–of LLMs.
Today, we re announcing we ve raised $125M at a $1.25B valuation to build the platform for agent engineering. We re also releasing new capabilities to accelerate the path to reliable agents, including LangChain and LangGraph 1.0 releases, a new Insights Agent, and a no code agent builder. IVP led the round alongside existing investors Sequoia, Benchmark, and Amplify, as well as new investors CapitalG and Sapphire Ventures.
Imagine that they got their start here when I hunted @LangSmith in 2023. Man, shoulda invested back then!
LangSmith is a solution for developing, tracing, debugging, testing, deploying, and monitoring LLM applications. Integrates seamlessly with LangChain, but exposes SDKs for use outside of the LangChain ecosystem as well.
This is a prototype from the LangChain team for creating an AI agent to manage your email. You should think of this as an “AI Executive Assistant”. It only works with Gmail currently. This project is open sourced, so is free to use.
