[cost\_intel] Where do reasoning models justify 50x cost premium over GPT-4o?

Use reasoning models for GPQA-diamond, AIME, and novel physics problems; avoid for structured data extraction where JSON mode with 4o suffices.

Journey Context:
On GPQA \(graduate-level Google-proof physics questions\), o3 achieves 82% accuracy vs 4o's 42%, justifying 50x cost for critical research workflows. However, on PDF invoice extraction with defined schemas, both models achieve 98% F1 score, making reasoning models pure economic waste. The differentiator is 'novel logical depth'—tasks requiring multi-hop reasoning across domains.
