Shreya uses Google Sheets to run her evals, but [Airtable field agents](https://wow.pjh.is/journal/airtable-field-agents) are a better "no-code" option.

If you're a developer, try [PromptFoo](https://www.promptfoo.dev/docs/getting-started/).

Ideally, your evaluations are based on deterministic code (e.g. "pass" if response contains a string, "fail" otherwise). But you'll often have to use an LLM to judge your outputs. They share an example at [48:50](https://www.youtube.com/watch?time_continue=2930\&v=BsWxPI9UM4c).
