Using Entra ID for authentication

03/14/2026, 9:16 AMHi,
I'm currently exploring using BAML for a new project at work. I can't seem to get Entra ID auth to work. Is this not supported yet?
In the meantime I use the modular API to use my own python client from the openAI SDK. That also has the plus of utilizing responses API.

03/14/2026, 9:46 AMYeah used that when using modular API 🙂
It would be great to have it, since it is our only authentication method towards Azure OpenAI. Would it be possible to use openai-responses targeting Azure OpenAI ressource using EntraID as auth?
Please don't rush for my sake. I'm just doing preliminary discovery before we start the implementation. If its available in the coming weeks, that would suit me greatly.

03/14/2026, 9:51 AMwe do a thing every friday where each of us picks one problem a user is having and tries to ship it within the next release. i was trying to pick one anyways haha
so you really are doing me a favor by giving me this suggestion! 😉

03/14/2026, 10:00 AMAnother idea for your friday problem solver: Making it possible to control streaming on fields added via typebuilder 🙂
That or some inheritance on classes.
I would like to dynamically add some fields to my Extract class, where these are tagged @stream.done
Currently I can either do Extract @stream.done and have to wait for all fields to finish or I get partial streams for each field.

03/14/2026, 10:00 AMinheritance is something we're thinkign about deeply!

03/14/2026, 10:01 AMbut still a tricky thing atm because we dont like the way python / TS do it.
and traits in rust are also too complicated

03/14/2026, 10:01 AMso sadly no clear answer so far 🙁

03/15/2026, 11:39 AMWhen Steve Jobs learned 1 month before the release of the first iPad, that the team had just scaled up the UI from the iPhone version, he gave them an ultimatum: either redesign it for the new size, or it wouldn't be included at all.
The first iPad shipped without a calculator app.
And the first BAML shipped without inheritance. Cheers to not shipping junk! 🥂

So far I've found all the limitations of BAML to be the feature though. That's the whole point of managing prompts in a DSL. Do 1 thing good and build amazing tooling around it.
I prefer to work with a limited ✨ but amazing ✨ tool
- than a Swiss army knife dynamically typed runtime-only GPL multi-domain tool that can get me to mars in a rusty Tesla with a @types extension that makes everything resolve to

Eager to get my hands on more BAML reps
