Chain-of-Density

Chain-of-density is an iterative summarisation technique: the model produces a first summary, then rewrites it several times at fixed length, adding missing entities and details each pass while compressing the rest. The final result is information-dense yet the same length. Example prompt: "Summarise this article in 60 words. Then rewrite the summary 4 times, keeping 60 words but adding 2-3 important previously-omitted entities each pass, without increasing length." The model returns a progression from generic to rich, specific summary.

Definition

Use it when you need short but information-dense summaries: abstracts, executive summaries, product blurbs, metadata. It is the right tool when packing maximum useful information into a fixed space matters.
