Use-Case Guide

Choosing an AI API for document analysis

Long documents make cost and accuracy trade-offs sharp. Every page you send is billed as input, and a model that misses a clause can be worse than no model at all.

Side-by-side pricing comparison

Active pay-as-you-go rates from our pricing catalog, sourced from each provider's official page. The catalog may lag new launches. Use the category filter to narrow the list.

Catalog rates are a single pricing snapshot, not a full tier schedule. This table does not select rates by prompt length; long prompts may cost more and change the ranking. Use the API cost calculator for supported Haiku 5.5 and xAI prompt tiers. Announced Google increases are not applied before their effective date.

Prices are per 1M tokens (standard pay-as-you-go). Always verify with your provider before budgeting.

How to evaluate a model on long documents

Test retrieval accuracy and input cost together, because they pull against each other.

  1. 01
    Plant-and-find accuracy

    Insert a few known facts at different depths of a real document and ask for them with citations. Record hit rate at your actual document lengths.

  2. 02
    Full context vs chunking

    Sending the whole document is simple but bills every page each time. Retrieval over chunks sends less. Price both for your query volume.

  3. 03
    Watch pricing thresholds

    Some providers change rates once a prompt passes a size threshold, for example 100K or 200K tokens. Check where your documents fall before using a flat rate.

  4. 04
    Caching repeated documents

    If many questions hit the same document, cached-input pricing can lower cost substantially. Check whether your model supports it in the table.

These official pricing references and our calculation methodology remain available while the live catalog loads. Confirm the provider's current rates and billing conditions before committing to a workload.

Frequently asked questions

Which model has the largest context window?
Context limits change frequently. Check the context column in the table above, and confirm on the provider's model page. Larger is not automatically more accurate.
Should I send the whole document or use retrieval?
For a handful of questions per document, sending it whole is simpler. For many questions or very large collections, retrieval usually costs less. Price both.
How many tokens is a PDF page?
It depends on density and formatting. Extract the text from a few real pages and run it through the token estimator; scanned pages may also need OCR.
Can I trust extracted figures?
Verify them. Ask the model to quote the source passage, then check that quote exists in the document.
Do these estimates include taxes or enterprise discounts?
No. Rates are standard pay-as-you-go prices from our active catalog, sourced from official pricing pages. Enterprise agreements, committed-use discounts, regional pricing, and taxes are not reflected. Confirm final pricing with the provider.
