Args: |

alibi_starting_size (int): Use `alibi_starting_size` to determine how large of an alibi tensor to |

create when initializing the model. You should be able to ignore this parameter in most cases. |

Defaults to 512. |

attention_probs_dropout_prob (float): By default, turn off attention dropout in Mosaic BERT |

(otherwise, Flash Attention will be off by default). Defaults to 0.0. |
