How to Network Multiple PCs for Local LLM Inference: A Hardware Setup Guide
BinaryGrind · reddit · 2026-07-26
A developer is seeking advice on how to combine several spare high-performance PCs (equipped with multiple RTX 5070s, a 4070 Ti Super, and up to 96GB of RAM) to run large language models (LLMs) and agents locally.
The user has experimented with LM Studio's LM-Link feature but found it only runs different models on different machines rather than distributing a single large model across a cluster. They are asking whether to network these machines, break them down into a single host, or utilize vLLM's multi-host capabilities, while expressing concerns about potential bottlenecks with 2.5GbE networking.
