Report #79523

[cost\_intel] Overusing frontier models for simple entity extraction and classification

Use Haiku/Flash/Mini for structured extraction/classification; quality delta is <2% but cost is 10-20x cheaper.

Journey Context:
Developers assume 'better model = better extraction', but for well-defined schemas \(JSON mode\), small models are highly deterministic. They only fail on ambiguous context requiring deep reasoning. Paying 10x for Opus/GPT-4 to extract names and dates is pure waste because the task requires pattern matching, not world knowledge.
