Assuming a standard single-spaced document with ~500 words per page, a 100 pages document contains approximately 50,000 words, which translates to roughly 64,000 tokens using o4-mini's tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
o4-mini has a context window of 256,000 tokens. A 100 pages document consumes only 25.00% 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 $0.0726. Using 24-hour async batch API queues drops this cost to $0.0363.
If your workflow repeatedly queries or chats with this same 100 pages document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.0176 per turn instead of $0.0704).
