# fas_arab_1000mb

Goldfish is a suite of monolingual language models trained for 350 languages.
This model is the <b>Persian</b> (Arabic script) model trained on 1000MB of data, after accounting for an estimated byte premium of 1.59; content-matched text in Persian takes on average 1.59x 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: fas_arab is a [macrolanguage](https://iso639-3.sil.org/code_tables/639/data) code. Individual language codes pes_arab (Iranian Persian) and prs_arab (Dari) are included in Goldfish, although with less data.

All training and hyperparameter details are in our paper, [Goldfish: Monolingual Language Models for 350 Languages (Chang et al., 2024)](https://github.com/tylerachang/goldfish/blob/main/goldfish_paper_20240815.pdf).

## 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.
