OCR API Benchmark 2026 — Speed, Accuracy, and Cost Compared

We benchmarked the top document extraction APIs on a standard set of test documents — invoices, receipts, forms, and multi-page reports — to measure real-world performance across three dimensions: speed, accuracy, and cost.

Speed (Single Page, Typed Invoice)

Note: Hyperscaler cold starts include Lambda/GCP function initialization. ParseFlow and Mistral are direct API calls — no infrastructure overhead.

Cost per 1,000 Pages (Forms + Tables)

ParseFlow: $8.00
Mistral OCR 4 (batch): ~$2.00 (parser only, no structured extraction)
Google Document AI: $40.00
Azure: $10.00
AWS Textract: $65.00

Key Takeaways

ParseFlow delivers the best balance of speed and structured extraction cost. Mistral OCR 4 is cheaper per page but requires significant post-processing to extract structured fields. The hyperscalers (Textract, Doc AI, Azure) cost 5–8x more for the same structured output, with slower response times due to their asynchronous pipeline architecture.
