We have been building BAML for around 3 years -- originally it was a DSL for getting structured outputs from llms using what we call 'llm functions'

Our users told us they wanted to do more, so we made it an actual turing-complete language, still with a focus on people building AI workflows and calling nondeterministic models. This is why we added very flexible testing capabilities into BAML itself for test parameterization, dynamic tests, etc.

As we were building it, we realized humans weren't going to be the ones writing the code, so we started researching what we could do on this front. This led us to design BAML to use all fully-qualified-names for everything (classes, enums,functions etc) to name one example. We found in some cases AI agents saved 30% tokens navigating baml codebases vs TypeScript ones. There's no imports to track down, etc.

We do aim to keep humans in the loop, and we'll do some more deep dives that tackle each feature.

I'll add it in!

- Created by an AWS team but aws logo is barely visible at the bottom.

- Actually cute logo and branding.

- Focuses on the lead devs front and center (which HN loves). Makes it seem less like a corporation and more like 2 devs working on their project / or an actual startup.

- The comment tone of "hey ive been working on this for a year" also makes it seem as if there weren't 10 6-pagers written to make it happen (maybe there weren't?).

- flashy landing page

Props to the team. Wish there were more projects like this to branch out of AWS. E.g. Lightsail should've been launched like this.
