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 Gemini 3.5 Flash-Lite's tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
Gemini 3.5 Flash-Lite has a context window of 1,000,000 tokens. A 250 pages document consumes only 16.66% 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 $0.0512. Using 24-hour async batch API queues drops this cost to $0.0256.
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 $0.004999 per turn instead of $0.05).
