[cost\_intel] Enabling extended thinking or reasoning modes without accounting for the massive token cost multiplier

Extended thinking \(Claude\) and reasoning models \(o1, o3-mini\) can consume 5-50x more tokens than standard inference. Only enable for tasks where reasoning depth genuinely improves outcomes: complex root-cause analysis, multi-step planning, architectural design, mathematical reasoning. Disable for extraction, classification, formatting, boilerplate generation, and well-structured tasks where the answer is straightforward.

Journey Context:
Extended thinking is powerful but the cost curve is steep and the quality improvement is highly task-dependent. A task that costs $0.01 with standard inference might cost $0.10-0.50 with extended thinking, and the quality delta ranges from negligible \(for structured tasks\) to transformative \(for novel reasoning\). The common mistake is enabling thinking tokens by default 'for better results' without measuring the actual quality-per-dollar improvement on the specific task distribution. The right call is to A/B test thinking vs. non-thinking on your real workload. For coding agents, thinking tokens are valuable for: understanding subtle bug root causes, planning multi-file refactors, and designing system architectures. They are wasteful for: writing boilerplate, formatting code, generating tests from clear specs, and simple lookups.
