Assuming a standard single-spaced document with ~500 words per page, a 250 pages document contains approximately 125,000 words, which translates to roughly 166,625 tokens using DeepSeek R1 (Reasoner)'s tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
DeepSeek R1 (Reasoner) has a context window of 64,000 tokens. A 250 pages document consumes only 260.35% 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 $0.0927. Using 24-hour async batch API queues drops this cost to $0.0464.
If your workflow repeatedly queries or chats with this same 250 pages document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.0233 per turn instead of $0.0916).
