Calling BAML Functions

Once you’ve generated the BAML client and set your environment variables, you can call BAML functions from your code.

You can check out more examples in the BAML Examples repo.

We’ll use function ClassifyMessage(input: string) -> Category for our example:

classify-message.baml

Python

TypeScript

Ruby (beta)

OpenAPI

BAML will generate b.ClassifyMessage() for you, which you can use like so:

main.py

1 import asyncio
2 
3 from baml_client import b
4 from baml_client.types import Category
5 
6 async def main():
7     category = await b.ClassifyMessage("I want to cancel my order")
8     print(category)
9     assert category == Category.CancelOrder
10 
11 if __name__ == '__main__':
12     asyncio.run(main())

1	import asyncio
2
3	from baml_client import b
4	from baml_client.types import Category
5
6	async def main():
7	category = await b.ClassifyMessage("I want to cancel my order")
8	print(category)
9	assert category == Category.CancelOrder
10
11	if __name__ == '__main__':
12	asyncio.run(main())
