Pre-Built Evaluators | LangSmith Evaluations - Part 5

With the rapid pace of AI, developers are often faced with a paradox of choice: how to choose the right prompt, how to trade-off LLM quality vs cost? Evaluations can accelerate development with structured process for making these decisions. But, we've heard that it is challenging to get started. So, we are launching a series of short videos focused on explaining how to perform evaluations using LangSmith.

This video introduces how to use LangSmith's many pre-built evaluators for tasks such as RAG (question answering), evaluating generations based upon supplied criteria, etc.
