As developers, we often think about translation as a binary choice: human or machine. But production systems handling diverse content types need more nuanced approaches. A recent analysis of translation service tiers highlights how different content requires different quality levels — and this maps directly to technical architecture decisions.

Let's explore how to build translation pipelines that automatically route content based on quality requirements, volume, and risk tolerance.
