Assuming a standard single-spaced document with ~500 words per page, a 500 pages document contains approximately 250,000 words, which translates to roughly 333,250 tokens using Gemini 1.5 Flash's tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
Gemini 1.5 Flash has a context window of 1,048,576 tokens. A 500 pages document consumes only 31.78% 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 $0.0251. Using 24-hour async batch API queues drops this cost to $0.0126.
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 $0.006248 per turn instead of $0.025).
