A blog post on dev.to explores the effectiveness of different context window packing strategies for LLMs, highlighting that maximizing context utilization does not necessarily mean retaining the most crucial information. The author demonstrates that a greedy approach, which fills the window but may cut off answers, performs poorly in retaining the actual answer span. An 'oracle' strategy, which prioritizes placing the answer document first, proves to be 100% effective in retaining the answer, even when other methods fail due to budget constraints or inaccurate token counting.
