What is context window management in RAG?
0:31
Context window management decides how many retrieved chunks, how much chat history, and how much system prompt fits in a single generation call. Token counting is essential because overflowing the window causes errors or silent truncation. Strategies include dynamically selecting top-k chunks until a token budget is reached, summarizing older chat history, and truncating long chunks with careful boundary selection. Larger context windows have increased available budgets since 2024, but lost-in-the-middle effects still penalize naive packing of many chunks.
