Report #66356

[cost\_intel] o1 overthinks simple JSON extraction tasks

Use GPT-4o with outlines/guidance libraries for schema-constrained generation; reserve reasoning models for extraction requiring cross-document inference or ambiguous entity resolution

Journey Context:
Reasoning models spend tokens 'thinking' about whether a field should be null vs empty string, burning $0.50 on a $0.01 task. Structured generation with regex constraints \(outlines, jsonformer\) achieves 99% schema compliance with 4o at 1/30th cost. The failure mode is using o1 for 'extract email from this text.' Only use reasoning when extraction requires 3\+ hops \(e.g., 'find the CEO's email from subsidiary press releases considering name changes'\).
