Pre-release

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
