[cost\_intel] Optimizing only input costs when output generation dominates for creative tasks
For tasks generating >2k output tokens \(creative writing, code generation, long-form analysis\), prioritize models with low output token costs \(Gemini 1.5 Pro at $0.30/1M vs GPT-4o at $10/1M\) even if input costs are higher; output can dominate total cost by 10:1 ratio in these workloads.
Journey Context:
Cost calculators often assume short outputs. For a creative writing task generating 4k tokens, GPT-4o costs $0.04 just for output, while Gemini 1.5 Pro costs $0.0012—a 33x difference. Input costs \($5 vs $3.50 per 1M\) are negligible in comparison. Signature: creative writing, code generation, detailed analysis outputs. The trap is using GPT-4 for long drafts when Gemini/Flash suffices. Alternative: streaming to reduce perceived latency, but cost is determined by total tokens generated, not time.
