Ask HN: How are you checking if your LLM is giving customers the right answer?

[navaed01]

Something that’s been bothering me is observability with LLMs and how to check it’s giving customers the right answer.

There seems to be multiple failure points: hallucinations, partial responses (missing facts), saying information does not exist, response accuracy depends on how and what is being asked.

How are you measuring this in production today? - Thumbs up/ down seems like a weak signal - Running a sample of ‘known queries’ Assumes you know what is being asked.

What have you tried that works for you?
