How much does document summarization cost?
Compare 14 AI models for document summarization. Prices shown at 10K calls/month with default token counts.
Summarization tasks compress long documents into concise overviews for faster reading. These tasks are input-heavy because the full source text must be included. Output stays relatively short compared to the original source document length.
What drives document summarization cost
The archetypal input-heavy task: the entire source document goes in, a short summary comes back. Cost is almost entirely a function of document length, and the output rate barely registers. Long documents can cross a provider's long-context threshold, where the whole request is re-priced at a multiple. Check the threshold before feeding in a hundred-page PDF as one call.
