Contextual Compression
Contextual compression is a technique used to reduce the size of the input context for a Large Language Model (LLM) while retaining its most relevant information, typically by summarizing or filtering.
/ quick answer
A set of techniques applied to raw input context (e.g., retrieved documents, conversation history) to reduce its token count before feeding it to a Large Language Model, typically involving summarization, filtering, or selective extraction of the most relevant information.

What's the difference between compression and chunking?
Chunking is the process of breaking down a large document into smaller, predefined segments (chunks) for easier storage and retrieval. Compression, on the other hand, actively reduces the content within those chunks or retrieved segments by summarizing or filtering, aiming to maintain core information while reducing token count.
Can contextual compression lead to loss of important details?
Yes, there's always a trade-off. Over-compression can lead to the loss of nuanced or specific details. The key is to balance reduction in token count with the preservation of critical information. Advanced compression methods often prioritize information based on its relevance to the current user query or task.
