What drives pdf summarization cost
PDFs are the worst case for input cost: extracted text carries page furniture, headers, and footnotes that inflate token counts well past what the content warrants. Cleaning the extraction before sending it often cuts more cost than changing models. Long PDFs also routinely cross long-context pricing thresholds, so chunking is both a quality and a cost decision.
For Claude Fable 5.1 specifically, that means output tokens cost 5.0x more than input, at $50.00 vs $10.00 per MTok. At this use case’s 15,000/1,500 token split, output accounts for 33% of the $0.2250 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $10.00 | 15,000 |
| Output | $50.00 | 1,500 |
Prompt caching: 98% off input tokens
Caching drops input cost from $10.00 to $0.25/MTok. For repeated system prompts, that saves $0.1462 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.
