Self-hosted Inference Orchestrators Compared: LocalAI, exo, GPUStack, vLLM

A detailed benchmark comparison of four major self-hosted inference orchestrators reveals key differences in performance, ease of deployment, and feature sets. This analysis evaluates LocalAI for its simplicity and CPU-friendly approach, exo for distributed inference across multiple devices, GPUStack for enterprise-grade resource management, and vLLM for high-throughput serving with sophisticated batching strategies.

For practitioners deploying LLMs locally or in hybrid cloud environments, understanding these orchestrator trade-offs is critical. The comparison likely covers aspects such as memory efficiency, latency characteristics, multi-GPU support, model format compatibility (GGUF, SafeTensors, etc.), and ease of integration with existing infrastructure. Each platform serves different deployment scenarios—from resource-constrained edge devices to multi-node clusters.

This benchmark helps teams select the right orchestration layer based on their specific constraints around hardware availability, inference throughput requirements, and operational complexity tolerance.
