What drives email summarization cost

Individually cheap, collectively expensive. A single thread is small, but summarization runs across an inbox at volume, so per-call price multiplied by message count is the number that matters, not the cost of any one summary. This is the use case where a fast-tier model and batch processing usually beat a smarter model outright.

For Claude Fable 5 specifically, that means output tokens cost 5.0x more than input, at $50.00 vs $10.00 per MTok. At this use case’s 3,000/500 token split, output accounts for 45% of the $0.0550 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $10.00 to $1.00/MTok. For repeated system prompts, that saves $0.0270 per call.

Batch API: 50% off all tokens

Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
