Assuming a standard single-spaced document with ~500 words per page, a 500 pages document contains approximately 250,000 words, which translates to roughly 320,000 tokens using o3-mini's tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
o3-mini has a context window of 200,000 tokens. A 500 pages document consumes only 160.00% of its total window, easily fitting in a single prompt without requiring chunking or vector search.
Ingesting the document and outputting a concise 500-token executive summary costs $0.3542. Using 24-hour async batch API queues drops this cost to $0.1771.
If your workflow repeatedly queries or chats with this same 500 pages document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.176 per turn instead of $0.352).
