Document size is the main cost driver
Document summarization cost usually rises with input length. Reports, policies and contracts can be much larger than chat messages, especially when OCR or extracted text includes tables and repeated headers.
For a useful estimate, paste extracted text from a representative document and set monthly interactions to the number of documents processed.
| Document type | Cost driver | Planning tip |
|---|---|---|
| PDF report | Long extracted text | Estimate from an average report, not a short sample |
| Contract | Detailed output requirements | Include clauses and extraction instructions |
| Policy document | Large input context | Chunk long documents if they exceed context limits |
