thanks for the shoutout, we benchmarked our approach against other function-calling techniques and we've been able to beat all other approaches every time (even by 8%!) just by getting better at parsing the data and representing schemas with less tokens using type definitions instead of json schema.

You can take a look at our BFCL results on that site or the github: https://github.com/BoundaryML/baml

We'll be publishing our comparison against OpenAI structured outputs in the next 2 days, and a deeper dive into our results, but we aim to include this kind of constrained generation as a capability in the BAML DSL anyway longterm!
