UnverifiedOpenAI 使用基于字节对编码（BPE）的 tiktoken 分词器将文本切分为 Token73% similarUnverifiedOpenAI uses the tiktoken tokenization algorithm, and Google uses the SentencePiece tokenization algorithm.67% similarUnverifiedThe Byte Pair Encoding (BPE) tokenization algorithm was originally introduced by OpenAI in GPT-2, splitting text into subword units by iteratively merging high-frequency character pairs.64% similarUnverifiedMainstream large models generally use Byte Pair Encoding (BPE) or its variants (such as SentencePiece and tiktoken) for tokenization.64% similarUnverifiedModern large language models universally use BPE algorithm variants to build tokenizers, with OpenAI's tiktoken, Google's SentencePiece, and HuggingFace's Tokenizers library being the three mainstream implementations63% similar
