The original Transformer consists of an Encoder and a Decoder; BERT-type models use only the Encoder and excel at understanding and classification, while GPT-type models use only the Decoder and focus on text generation.

VerifiedThe Transformer's encoder is responsible for mapping the input sequence to a contextual representation and is suitable for classification and understanding tasks, while the decoder autoregressively generates the output sequence and is suitable for text generation tasks80% similarUnverifiedThe Transformer spawned two major technical paths: the encoder approach represented by BERT (excelling at understanding) and the decoder approach represented by GPT (excelling at generation), with the decoder approach becoming the dominant paradigm for large language models79% similarUnverifiedTransformer架构由Google于2017年提出，Encoder负责将输入文本编码为高维向量表示，Decoder基于编码表示逐token生成输出文本78% similarUnverified大语言模型通常采用仅解码器（Decoder-only）的Transformer变体，通过因果掩码确保每个位置只能关注其之前的token77% similarUnverifiedTransformer uses Positional Encoding to retain word order information while performing parallel computation.73% similar
