## AI overview

The article presents Boundary's BAML as a typed programming language for making LLM workflows more reliable. It describes using functions with defined inputs and outputs to structure prompts and extract data from messy model responses, with ClickHouse providing analytics for execution tracing and type-level monitoring.

## Source excerpt

"How do we move beyond prompting as guesswork, and start treating it like real programming, so we can build pipelines that are reliable not just in our code, but in our data too? That's BAML. And it would only have been possible with ClickHouse."
