Researchers have explored the effectiveness of different text embeddings for diffusion language models (DLMs), finding that scaling embeddings within the T5 family, such as from T5 to T5Gemma-1 and then to T5Gemma-2, significantly improves generative performance. However, the highly discriminative nature of T5Gemma-2 embeddings can hinder generation by separating plausible alternative words. To address this, the researchers developed a distillation method where a student encoder learns from the teacher's decoded probabilities, creating a more connected and diffusible latent space. This approach resulted in a medium-sized DLM achieving a generation perplexity of 17.8 on OpenWebText, outperforming GPT-2-M. AI
