afr_latn_1000mb

Goldfish is a suite of monolingual language models trained for 350 languages. This model is the Afrikaans (Latin script) model trained on 1000MB of data, after accounting for an estimated byte premium of 1.04; content-matched text in Afrikaans takes on average 1.04x 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: afr_latn is an individual language code. It is not contained in any macrolanguage codes contained in Goldfish (for script latn).

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