Report #56925

[cost\_intel] Using reasoning models for simple classification or entity extraction wastes 10x cost with no accuracy gain

Use GPT-4o-mini for binary/ternary classification; only escalate to o1 if the task requires handling >3 edge cases that explicitly require counterfactual reasoning

Journey Context:
Reasoning models shine on 'System 2' tasks $math, debugging$ but suffer 'overthinking' on pattern-matching tasks. Benchmarks show o1-preview achieves 94% on simple NER vs 92% for GPT-4o, but costs $15 vs $0.30 per 1M tokens. The cost-per-correct-answer curve is flat for simple tasks, exponential for complex ones.
