Good VQA performance is taken as evidence that the model will perform well on a broader range of tasks that require both visual and language inputs. Howeve…

Tokenization is an understudied and often neglected component of modern LLMs. Most published works use a single tokenizer for all experiments, often borrowed from another model, without performing ablations or analysis to optimize tokenization. Moreover, the tokenizer is generally kept unchanged whe…
