Assuming a standard single-spaced document with ~500 words per page, a 100 pages document contains approximately 50,000 words, which translates to roughly 66,650 tokens using Grok 4.1 Fast's tokenizer. Dense PDF tables, legal boilerplate, and OCR scans may increase this by 20–30%.
Grok 4.1 Fast has a context window of 2,000,000 tokens. A 100 pages document consumes only 3.33% 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 $0.0136. Using 24-hour async batch API queues drops this cost to $0.00679.
If your workflow repeatedly queries or chats with this same 100 pages document, prompt caching reduces subsequent turn input costs by up to 90% (to $0.002666 per turn instead of $0.0133).
