UnverifiedBoth the GPT series and the Claude series employ a tokenization mechanism similar to Byte-Pair Encoding (BPE).81% similarUnverifiedThe GPT series uses a BPE (Byte Pair Encoding) tokenizer, in which the em dash is encoded as an independent token.78% similarUnverifiedMainstream large language models generally adopt BPE (Byte Pair Encoding) or its variants (such as SentencePiece) as tokenization algorithms, and GPT-4's vocabulary is approximately 100,000 tokens.77% similarVerifiedThe GPT series uses tiktoken (based on BPE encoding) for tokenization.76% similarVerifiedThe BPE (Byte Pair Encoding) algorithm commonly used in the GPT series builds a vocabulary by counting the frequency of adjacent character pairs and merging the highest-frequency character pairs.76% similar
