لانغ تشين تكشف عن منصة لانغ سميث لوكلاء الذكاء الاصطناعي بعد تمويل بـ300 مليون دولار

We just raised 300 million in our series C at a 3 billion valuation to help every company own its intelligence.

Over the past three years, millions of developers have used LangChain frameworks to build agents.

And today, we're putting everything we've learned into one platform, the new LangSmith.

Right now, everyone is building agents, but only a handful of them are transforming businesses.

Those that do are proactive, specialized, and they get better over time.

The only way to build these agents is to keep iterating on them.

See what they did, measure it, fix it, and ship it again.

Today, these steps are spread across multiple tools that weren't built for agents, and that's where LangSmith comes in.

LangSmith is built for and powered by agents, supporting the entire agent development lifecycle, so you can build, run, improve, and govern every agent.

Here's how it works. LangSmith lets anyone on your team build an agent in natural language or in code.

You can use LangChain's open-source harnesses or any harness.

Deploy your agent in one click. LangSmith handles the infrastructure so it can run and scale reliably.

Workday adopted LangSmith, and deploying a new agent went from five months to under a day.

Every agent across your company is visible from one place, so you always know what's running.

You can trace every step an agent takes and see exactly where it went wrong.

Every time you make a change, evals test the new version, so you know it's better before it ships.

LangSmith Engine monitors your agents 24/7 to find failures.

It writes the fixes and evals for you. All you have to do is review and merge.

Teams using LangSmith Engine improve their agents five times faster.

Every run is governed by LangSmith, with model fallbacks, cost controls, and protection for sensitive data.

Today, LangSmith processes billions of traces a month, with more than 7,000 customers relying on it every day.

Our goal is to help every company own its intelligence, from the agents it builds to the systems that improve and govern them.

That starts with helping teams build agents they can trust in production.

So we're providing LangSmith Engine for free to all new plus subscribers through the end of the year.
