Assuming a standard single-spaced document with ~500 words per page, a 50 pages document contains approximately 25,000 words, which translates to roughly 33,325 tokens using Gemini 3.5 Flash (OpenRouter)'s tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
Gemini 3.5 Flash (OpenRouter) has a context window of 1,048,576 tokens. A 50 pages document consumes only 3.18% 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 $0.0545. Using 24-hour async batch API queues drops this cost to $0.0272.
If your workflow repeatedly queries or chats with this same 50 pages document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.004999 per turn instead of $0.05).
