SMG gRPC proto definitions for vLLM, TRT-LLM, MLX, TokenSpeed, and SGLang
Decision gist · record as of 2026-08-14
Yes, if you are building or deploying an SMG-based inference system or integrating with vLLM, TensorRT-LLM, or SGLang via gRPC. The package is actively maintained, has no known vulnerabilities, low install friction, and a permissive license. Install only if you actually need these specific proto stubs; it is a narrow-purpose dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; grpcio>=1.81.1 and protobuf>=5.26.0 must be installed.
- Low friction: pure Python wheel with only two runtime dependencies (grpcio and protobuf).
- Repository is active with recent commits and no archived status.

What it is and what it does
smg-grpc-proto is a package of pre-compiled Python gRPC service stubs for the Shepherd Model Gateway (SMG), an orchestration layer for large language model inference. It bundles protocol buffer definitions for four LLM inference backends: SGLang scheduler and encoder services, vLLM engine service, and TensorRT-LLM service. Rather than requiring users to compile proto files themselves, the package ships ready-to-use Python stubs generated at build time.
The package is lightweight—a pure Python wheel with only grpcio and protobuf as runtime dependencies—and targets Python 3.10 and later. It is primarily useful for developers building clients or integrations that communicate with SMG-orchestrated inference services, or for projects like vLLM that need to speak to multiple backend engines via gRPC.
Use it for
- Building a client application that communicates with SMG-orchestrated vLLM or TensorRT-LLM inference engines.
- Integrating multiple LLM backends (SGLang, vLLM, TRT-LLM) into a single inference orchestration system.
- Testing or developing SMG itself by importing the proto stubs without manually compiling proto files.
- Deploying inference services that use gRPC for inter-service communication in a distributed LLM system.
