Nope, a decoder only transformer is a variant of the original architecture proposed by Google [1]. All variants of GPT that we know about (1 through 3) all roughly use this same architecture which takes only the decoder stack from the original Google paper and drops the encoder [2] [1] Original Google Paper - https://arxiv.org/abs/1706.03762 https://arxiv.org/abs/1706.03762 [2] Original GPT Paper - https://s3-us-west-2.amazonaws.com/openai-assets/research-covers/language-unsupervised/language_understanding_paper.pdf https://s3-us-west-2.amazonaws.com/openai-assets/research-co...
