Best AI models for cost-sensitive tasks

Cheap-and-fast models for high-volume work where 80% quality at 5% cost is the right trade.

Triage, classification, lightweight transforms, and high-fanout fanouts (one prompt, many rows) all reward cheap models with predictable latency. Reserve the flagship LLMs for the few prompts where quality actually moves the metric.
