arz_arab_full

Goldfish is a suite of monolingual language models trained for 350 languages. This model is the Egyptian Arabic (Arabic script) model trained on 122MB of data (all our data in the language), after accounting for an estimated byte premium of 1.55; content-matched text in Egyptian Arabic takes on average 1.55x as many UTF-8 bytes to encode as English. The Goldfish models are trained primarily for comparability across languages and for low-resource languages; Goldfish performance for high-resource languages is not designed to be comparable with modern large language models (LLMs).

Note: arz_arab is an individual language code. However, you may also want to consider the arb_arab (Standard Arabic) models which are trained on more data.

All training and hyperparameter details are in our paper, Goldfish: Monolingual Language Models for 350 Languages (Chang et al., 2024).

Model details:

To access all Goldfish model details programmatically, see https://github.com/tylerachang/goldfish/blob/main/model_details.json. All models are trained with a [CLS] (same as [BOS]) token prepended, and a [SEP] (same as [EOS]) token separating sequences. For best results, make sure that [CLS] is prepended to your input sequence (see sample usage linked above)! Details for this model specifically:

• Architecture: gpt2
