ByteDance has introduced a new framework called Over-Tokenized Transformers, which aims to enhance vocabulary design in language models. This innovative approach reduces costs associated with larger vocabularies to less than 5% while achieving performance comparable to models with double the size, without incurring additional costs through vocabulary size scaling. The framework decouples input and output tokenization, potentially unlocking new pathways for advancements in artificial intelligence and machine learning. Additionally, Google DeepMind has proposed a technique named TokenVerse, which allows for multi-concept personalization by utilizing a pre-trained text-to-image diffusion model to generate new images based on learned concepts in desired configurations.
