Multimodal signals typically exhibit modality-specific information that has distinct structure but complementary semantics (Dong et al., 2023). This complementary property allows us to utilize deep language comprehension to enhance cross-modal image generation (Saharia et al., 2022). However, the potential of multimodal creation to improve comprehension remains largely unexplored. Learning Objective Our aim is to leverage MLLMs to model distributions via direct pixel space sampling. Here, the pretrained SD functions as a score metric, distilling the learned data distribution. This approach is similar to Score Distillation Sampling (Poole et al., 2023) (SDS, also known as Score Jacobian Chaining (Wang et al., 2023a)). In this context, image posterior is learned in a DeepDream-like manner (Mordvintsev et al., 2015), using MLLMs’ conditional parameterization. Conditional Embeddings Rather than converting the output space of MLLMs to align with CLIP, we propose to query MLLMs using learned embeddings. Consequently, MLLMs-enriched semantics serve as diffusion conditioning, and the distribution is implicitly modeled through synthesis sampling.
