Technical implementation details of the chunking strategy
Yek provides industry-leading intelligent chunking technology, with its core innovation being a dual metric chunking system. The tool allows users to specify the upper limit of chunking via the -max-size parameter, which supports either the number of tokens (e.g., 128K) or byte units (e.g., 10MB) as the metric. This dual-measure design addresses the preprocessing needs of different types of LLM inputs.
In token counting mode, Yek employs an approximate computation algorithm that ensures computational efficiency while maintaining reasonable segmentation accuracy. When dealing with programming language source code, the tool recognizes syntactic structures to avoid splitting in the middle of critical code segments. For natural language documents, chunking at paragraph boundaries is prioritized.
Byte mode is more suitable for binary data processing or strict storage limitation scenarios, and its chunking process realizes efficient processing through memory mapping technology. Both modes use a sliding window algorithm to ensure that the chunked content maintains semantic coherence and avoids information fragmentation.
