TL;DR.<\/strong> The context window is the part of an AI model that holds what you give it in a single request, and in 2026 it is huge. Anthropic, OpenAI and Google all list flagship models with about one million tokens of context, which by Google’s own conversion rate (100 tokens is about 60-80 English words) is roughly 600,000 to 800,000 words. The temptation is to paste everything in and let the model sort it out. The research says that is a mistake. In the RULER benchmark, 17 models all claimed 32K tokens or more, but only half held satisfactory performance at 32K (Hsieh and colleagues, 2024). In NoLiMa, a test that removes literal keyword matches, 11 of 13 models fell below half of their short-context score at 32K, and GPT-4o dropped from 99.3 to 69.7 percent (Modarressi and colleagues, 2025). Anthropic’s own documentation now calls the context window the model’s “working memory” and warns that accuracy and recall degrade as token count grows. Humans have the same constraint at a smaller scale: working memory holds about four chunks of new information (Cowan, 2001), and cognitive load theory has shown since 1988 that how information is presented matters as much as how much there is (Sweller, van Merrienboer and Paas, 2019). The CEO move is to treat context as a budget with a cost per token. The student move is to write prompts you could check yourself, using the Load-Fit Prompt method below.<\/p>\n

This piece is about the single request: what to put in it, in what order, and how much.<\/p>\n
