Transcript
0:00 I'm excited to announce the release of our latest LangChain Academy course, LangSmith Essentials. In this quickstart course, you'll learn to observe, evaluate, and deploy an AI agent in less than 30 minutes. Testing applications is an essential part of the development lifecycle, but LLM systems are non-deterministic, meaning we can't predict exactly what output a given input will produce. When you add multi-turn interactions and tool-calling agents into the mix, the process becomes even more complex and less straightforward than traditional software testing.
0:33 And that's where LangSmith comes in. LangSmith is a comprehensive platform for agent engineering that helps AI teams use live production data for continuous testing and improvement. In this course, you'll learn how to trace your agent step by step to understand its behavior and fix issues that slow it down or hurt quality. When building agents, it's easy to get stuck guessing why performance changes or which version actually works better. You'll learn how to move beyond this guesswork and evaluate your system in real world conditions with live requests.
1:06 We'll also dive into how to level up your prompt engineering beyond the “vibe check,” using real evaluation metrics and A/B testing to understand what truly drives better results. And lastly, you'll learn how to deploy an agent. Deploying agents often means wrestling with infrastructure, state management, and custom endpoints. We'll show you how to skip the complexity and deploy with a single click using LangSmith Deployment. I'm excited for you to dive into this new course and learn how to build more reliable agents.
1:35 You can get started today.
