prs_arab_full

Goldfish is a suite of monolingual language models trained for 350 languages. This model is the Dari (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 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).

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
• Parameters: 124770816
• Maximum sequence length: 512 tokens
• Training text data (raw): 270.74MB
• Training text data (byte premium scaled): 162.705MB
• Training tokens: 37549568 (x10 epochs)
• Vocabulary size: 50000
• Compute cost: 1.91613547118592e+17 FLOPs or ~18.1 NVIDIA A6000 GPU hours

Training datasets (percentages prior to deduplication):

• 99.28229%: NLLB (CommonCrawl and ParaCrawl)
