In this episode of AI Lab, we explore the full journey from compute and inference to workflows, quality controls, and measurable results. We unpack why a faster model can still sit inside a slow application, how retries and human review change the economics, and why cost per successfully completed task matters more than token price alone.

Topics include choosing between managed APIs and self-hosting, finding bottlenecks through end-to-end observability, evaluating what agents actually accomplish, and enforcing data permissions throughout the workflow.

The practical starting point: define what successful work looks like, measure one representative workflow, and use that evidence to guide your infrastructure decisions.

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.
