Assuming a standard single-spaced document with ~500 words per page, a 1 page document contains approximately 500 words, which translates to roughly 640 tokens using o1 (Reasoning)'s tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
o1 (Reasoning) has a context window of 200,000 tokens. A 1 page document consumes only 0.32% 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 $0.0396. Using 24-hour async batch API queues drops this cost to $0.0198.
If your workflow repeatedly queries or chats with this same 1 page document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.0048 per turn instead of $0.0096).
