# prs_arab_full

Goldfish is a suite of monolingual language models trained for 350 languages.
This model is the <b>Dari</b> (Arabic script) model trained on 162MB of data (all our data in the language), after accounting for an estimated byte premium of 1.66; content-matched text in Dari takes on average 1.66x 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: prs_arab is an [individual language](https://iso639-3.sil.org/code_tables/639/data) code. Macrolanguage code fas_arab (Persian) is included in Goldfish. Consider using that model depending on your use case.

All training and hyperparameter details are in our paper, [Goldfish: Monolingual Language Models for 350 Languages (Chang et al., 2024)](https://www.arxiv.org/abs/2408.10441).

## 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)!
