VerifiedA token is the smallest semantic unit segmented by subword tokenization algorithms such as BPE, and is not simply equivalent to a single character or word.75% similarVerifiedThe BPE algorithm originates from the field of data compression and builds a vocabulary by iteratively merging high-frequency character pairs.75% similarUnverified从表征到有限词汇的映射过程本质上是一种有损编码（Lossy Encoding）72% similarVerifiedLarge models process text using Token (word element) as the minimum processing unit, with tokenizers handling the segmentation.72% similarVerifiedModern LLMs generally use BPE (Byte Pair Encoding) or WordPiece algorithms for tokenization.71% similar
