-   The chunk size of 500 characters is chosen to fit within the context size limit of the embedding model used in this tutorial, but could be raised up to 4096 characters for `bge-multilingual-gemma2` model (or slightly more as context size is counted in tokens). Keeping chunks small also optimize performance during inference.
