SMG Python Bindings

This directory contains the Python bindings for SMG (Shepherd Model Gateway), built using maturin and PyO3.

Quick Start

Installation

pip install maturin
cd smg/bindings/python
maturin develop --features vendored-openssl

Usage

The smg serve command launches backend workers and the SMG router in a single command:

# sglang with gRPC (default)
smg serve --backend sglang --model-path /path/to/model --port 8080

# sglang with HTTP
smg serve --backend sglang --model-path /path/to/model --port 8080 --connection-mode http

# vLLM (gRPC only)
smg serve --backend vllm --model /path/to/model --port 8080

# TensorRT-LLM (gRPC only)
smg serve --backend trtllm --model /path/to/model --port 8080

# Multiple workers (data parallel)
smg serve --backend sglang --model-path /path/to/model --port 8080 --dp-size 4

Serve Options

Option Default Description
--backend sglang Backend to use: sglang, vllm, or trtllm
--connection-mode grpc Connection mode: grpc or http. vllm/trtllm only support grpc
--host 127.0.0.1 Host for the router
--port 8080 Port for the router
--dp-size 1 Data parallel size (number of worker replicas)
--worker-host 127.0.0.1 Host for worker processes
--worker-base-port 31000 Base port for workers
--worker-startup-timeout 300 Seconds to wait for workers to become healthy

Backend-specific options (e.g., --tensor-parallel-size, --quantization) are passed through to the backend.
