Report #92917

[cost\_intel] Using frontier models for simple JSON extraction where Haiku/Flash suffice

Route flat-schema extractions \(under 5 fields, no deep nesting\) to Claude 3.5 Haiku or Gemini 1.5 Flash; reserve Sonnet/Pro for nested or relational schemas.

Journey Context:
Haiku/Flash are 50-100x cheaper per token than frontier models. For flat schemas, quality is within 1-2%. The cliff happens on nested objects or when entity resolution requires deep context understanding. Watch for 'null' injections or hallucinated keys on smaller models as the degradation signature.
