Free Tier Limits
Google Cloud Vision offers 1,000 free pages/mo recurring forever. Azure offers 500 pages/mo. AWS offers 1,000 pages/mo for the first 3 months.
The Table Surcharge
Extracting tables can increase your bill by 7x-10x on legacy cloud APIs. Azure Document Intelligence Layout model ($10/1k) is 33% cheaper than AWS Textract Tables ($15/1k).
Vision-Language Model Shift
Vision-Language models like Mistral OCR 4 charge flat pricing ($2.00-$4.00/1k pages) covering text, HTML tables, and LaTeX math formulas with zero add-on charges.
❓ OCR Pricing & Billing FAQs
How do OCR APIs bill for multi-page documents? ▼
Virtually all cloud OCR APIs (AWS, Google, Azure, Mistral, LlamaParse) bill on a per-page basis rather than per-document. For example, a 10-page PDF uploaded to AWS Textract counts as 10 page units.
Why does Table Extraction cost so much more on legacy cloud APIs? ▼
Basic OCR only detects character bounding boxes and raw text strings. Table extraction (like AWS Textract Tables or Azure Layout) uses deep learning spatial graph networks to reconstruct rows, columns, merged headers, and nested cell relationships, which requires significantly more GPU compute. Modern VLMs like Mistral OCR 4 and olmOCR-2 output HTML tables natively in a single pass.
Are there hidden fees in OCR API billing? ▼
Common hidden costs include: asynchronous PDF storage read/write charges (S3/GCS buckets), API querying fees (e.g. AWS Queries adds $25/1k), Azure Custom Classification triage fees ($50/1k), and LlamaParse unrouted Agentic Plus runs ($56.25/1k).
How much does it cost to self-host open-source OCR and VLMs? ▼
With open-weight models like olmOCR-2, DeepSeek-OCR, and PaddleOCR-VL, you pay $0 in software licensing fees. Hosting on dedicated GPU cloud instances (like an AWS A10G or A100) translates to an effective compute cost of ~$0.05 to $0.176 per 1,000 pages.
