The Inference Engine: The Hidden Cost of Local AI

You’ve chosen the model. You’ve invested in the hardware. So why is your local AI still slow—or more expensive than expected?

In this episode of AI Lab, we explore the inference engine: the software that turns model weights and computing power into usable responses. We discuss how engine selection and configuration influence latency, memory use, and deployment costs, from desktop experiments to production workloads.

We cover: • Where tools such as LM Studio, Ollama, llama.cpp, and vLLM fit. • How model architecture, quantization, and KV cache affect deployment choices. • Why queues, network bottlenecks, and configuration errors can undermine performance. • What to measure when benchmarks and real-world results disagree.

A practical look at getting more from your AI infrastructure—and understanding what to investigate before buying more hardware.
