smg-grpc-servicer

gRPC servicer implementations for LLM inference engines. Supports vLLM, MLX, TokenSpeed, and SGLang.

Installation

For vLLM:

pip install smg-grpc-servicer[vllm]

For MLX:

pip install smg-grpc-servicer[mlx]

For TokenSpeed, install the TokenSpeed runtime first, then install the servicer bridge:

pip install smg-grpc-servicer

For SGLang:

pip install smg-grpc-servicer[sglang]

Usage

vLLM

vllm serve meta-llama/Llama-2-7b-hf --grpc

MLX

python -m smg_grpc_servicer.mlx --model meta-llama/Llama-2-7b-hf --host 0.0.0.0 --port 50051

TokenSpeed

python -m smg_grpc_servicer.tokenspeed --model meta-llama/Llama-2-7b-hf --host 0.0.0.0 --port 50051

SGLang

sglang serve --model-path meta-llama/Llama-2-7b-hf --grpc-mode

sglang                     ──optional──────>  smg-grpc-servicer (via --grpc-mode)

Backend dependencies are isolated via extras or runtime installs to avoid conflicts between vLLM, MLX, TokenSpeed, and SGLang.
