Unverified对于代码而言,一个token通常对应3-4个字符66% similarUnverifiedWhether prompt caching hits depends on byte-for-byte consistency of the request prefix; if even one character at the beginning differs, the entire cache is invalidated.65% similarUnverifiedEncoding text into token IDs and then decoding back to text does not necessarily yield a string identical to the original input (the round-trip consistency problem).65% similarUnverifiedDifferent strings may be caused only by format drift (different key order, 1 vs 1.0, whitespace, Markdown code fences), while the logic may be completely identical.64% similarUnverifiedThe byte fallback mechanism decomposes characters not found in the vocabulary into their corresponding UTF-8 byte sequences when the tokenizer encounters them, mapping each byte to a special token in the form of <0xE4>.64% similar
