How much does email summarization cost?

Compare 14 AI models for email summarization. Prices shown at 10K calls/month with default token counts.

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.
