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.
