Doubao (ByteDance)

1 glitch tokens

These tokens have been publicly documented on this model or model family. Inclusion does not mean that every version still shows the same behavior.

<think_never_used_51bce0c785ca2f68081bfa7d91973934>

A special token in Doubao's vocabulary: a <think_never_used_ prefix followed by a hash — judging by the name, likely a reserved placeholder prefilled into the vocabulary before training (akin to GPT-J's reserved <|extratoken_xx|> slots). The Zhihu source gives no further detail, listing it simply as a Doubao dirty token.
