| Challenge: | a number of pre-trained language models use sequences of tokens corresponding to word units . token-free models that operate directly on raw text have many advantages . |
| Approach: | They propose a standard Transformer architecture that can be used to process byte sequences . they also characterize trade-offs in terms of parameter count, training FLOPs, and inference speed . |
| Outcome: | The proposed model is more robust to noise and more robust on spelling and pronunciation tasks. |
