GoogleByt 5 Small
ByT5 Small, developed by Google, is a token-free language model that operates directly on raw UTF-8 bytes, making it particularly effective at handling noisy text data. It is best utilized after fine-tuning for a specific downstream task, and its standard Transformer architecture allows it to process byte sequences with minimal modifications.
