Microsoft's LLMLingua compresses prompts by removing filler tokens

Microsoft's LLMLingua project offers a method for compressing prompts by identifying and removing low-information tokens, such as articles and connectives, while retaining crucial elements like numbers, negations, and named entities. This technique aims to reduce token costs and latency by preserving the essential meaning of a prompt. Unlike simple truncation or abstractive summarization, LLMLingua's extractive compression is deterministic, cost-effective, and prevents the introduction of new information. AI

IMPACT Reduces LLM operational costs and latency by optimizing prompt efficiency.

RANK_REASON The item describes a technique for prompt compression developed by Microsoft, which is a tool or method rather than a core AI release or research breakthrough.

    Prompt Compression: Drop the Filler, Keep the Numbers, Negations and Entities

    <p>Most of your prompt is filler. A long system prompt, a stack of retrieved chunks, a block of few-shot examples — a large fraction of those tokens carry almost no information: articles, connectives, hedges, boilerplate. You pay for every one of them on <em>every</em> call, and …
