3.1 END-TO-END INTERLEAVED GENERATIVE PRETRAINING (I-GPT)

All natural documents can be regarded as carriers of text-image interleaved information. Text-only, images-only, and text-image pairs data, on the other hand, can be seen as special cases of interleaved corpora with different modality compositions. Thus, it is critical to empower the model with the capability to learn and generate free-form interleaved documents that form all possible distributions.

Interleaved Structure Learning To model the interleaved structure, the interleaved sequence is operated by extending a new special token before images. During training, DREAMLLM is trained to predict this token that indicates where an image emerges, and the conditional image synthesis is performed afterward, as introduced next. During inference, DREAMLLM will generate an image on its “free will” when this token is predicted.
