Automatic Evaluators
Automatic evaluators can be rule-based or graded by large language models (LLMs), and they can programmatically run on LLM input or output. Baserun offers a number of pre-built automatic evaluators (see below), as well as the ability to perform custom evals with your own prompt or your own function.
