Tutorial runs seven offline AI models on one DGX Spark via n8n
What happened
An October 19 n8n tutorial shows how to deploy seven models on a single NVIDIA DGX Spark and run AI workflows through a unified LiteLLM interface without calling cloud APIs. It covers model version pinning, service configuration and n8n hookup. The model stack used 108GB of memory. On an invoice field extraction task, turning off thinking cut latency from 12.1 seconds to 0.59 seconds. Parallel image generation hurt chat performance, dropping single-user chat speed 69% and four-user speed 65%. The tutorial says tasks sharing the GPU need scheduling.
