The Most Expensive Word in AI Agents Is “Parallel”

AI agents love searching everything in parallel. Your token budget probably doesn’t. A practical look at where the cost actually comes from in multi-agent systems and how to reduce it.

The Hidden Cost Curve of “One-Click” ML Observability

A “one-click” ML observability feature looked like an easy win until we modeled the cost at production scale. What seemed like basic logging turned into a high-volume data pipeline with non-trivial latency and a surprising price curve.

Tracing in Production: When 1–150ms Turns Into 700ms

We enabled tracing on a production ML system expecting a small latency overhead. Instead inference latency increased by ~700ms — far beyond the documented range, revealing how benchmarking assumptions may break under real workloads.
