[cost\_intel] Optimizing input token costs while ignoring the 3-5x output token price multiplier

For generative tasks, prioritize reducing output length. Sonnet charges $3/M input vs $15/M output \(5x\). Switching from 'write a detailed analysis' to 'list 5 key findings in bullet points' can cut output tokens 70% with disproportionate cost savings.

Journey Context:
Cost optimization instinct focuses on input—shorter prompts, caching, compression—but for generative tasks, output is where the money goes. A summarization call producing 2000 output tokens on Sonnet costs $0.03 in output alone vs maybe $0.006 for a 2K-token input. At 100K calls/day, that's $3000/day in output vs $600/day in input. The leverage is in constraining output: bullet points instead of prose, 'key findings only' instead of 'comprehensive analysis', code without explanatory comments. The quality tradeoff is often neutral or positive because verbose AI output has diminishing information density. A 500-token bullet list often communicates more than a 2000-token essay.
