[cost\_intel] Using o1 for high-volume PII redaction or JSON schema extraction

Use GPT-4o with Structured Outputs \(JSON mode\) for schema extraction; use o1 only if extraction requires multi-hop reasoning \(inferring missing fields from context\). Structured Outputs guarantee 100% schema adherence at 1/20th the cost.

Journey Context:
Reasoning models generate extensive internal monologue even for 'extract email' tasks, costing $0.06/1K vs $0.002/1K. GPT-4o's Structured Outputs use constrained decoding \(grammar sampling\) to enforce JSON schemas deterministically. The failure mode of instruct models \(hallucinating keys\) is eliminated by response\_format: \{type: 'json\_object'\}. Reserve o1 for ambiguous extraction \(e.g., 'infer the user's intent category from this messy conversation'\).
