This release is a pre-release and may not be stable for production use.
baml_core
Python bindings for the BAML runtime (powered by bex_engine).
baml_core is the bridge layer that generated baml_sdk packages
import at runtime: it provides the BamlRuntime singleton, the
protobuf encoder/decoder, the function/method factories, and the
Collector / BamlCtxManager observability primitives.
from baml_core import BamlRuntime
rt = BamlRuntime.initialize_runtime(
root_path=".",
files={"main.baml": baml_source},
sdk_root="my_sdk",
)
This package is generally consumed indirectly via the code generated
by baml-cli generate --target python — direct use is reserved for
runtime authors and bridge tests.
Requirements
- Python 3.10+
protobuf >= 6.31.1
