[cost\_intel] Task types where o1-mini outperforms o1-preview despite 80% lower cost

Deploy o1-mini for coding tasks under 200 lines, competitive programming, and structured math problems; it is 80% cheaper than o1-preview and actually outperforms it on algorithmic tasks with clear specifications, while o1-preview only wins on 'messy' real-world codebases with unclear requirements.

Journey Context:
The assumption that 'preview > mini' always holds is wrong due to training data composition. o1-mini is optimized for STEM and code competition formats, making it faster and more accurate on self-contained problems. o1-preview's strength is reasoning over ambiguous natural language specifications and legacy code comments. If your coding task includes 'TODO: fix this hack' or spans >5 files with unclear dependencies, use preview; for greenfield algorithm implementation, mini is superior and 5x faster.
