An open-source LLM tuner called PolyServe was developed to optimize model serving configurations. Benchmarking revealed several flaws in the tuner's assumptions, including a quality gate that failed to enforce its intended function and a search space that excluded the fastest configurations. The tuner also experienced issues with generalizing multi-GPU performance across different hardware setups. After addressing these bugs, the tuner demonstrated that using pre-quantized checkpoints could significantly increase throughput, though careful evaluation is still needed to assess the impact on answer quality.
