Goldfish is a suite of monolingual language models trained for 350 languages. This model is the <b>Maithili</b> (Devanagari script) model trained on 41MB of data (all our data in the language), after accounting for an estimated byte premium of 2.39; content-matched text in Maithili takes on average 2.39x 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: mai_deva is an individual language code. It is not contained in any macrolanguage codes contained in Goldfish (for script deva).

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): 99.73MB
• Training text data (byte premium scaled): 41.735MB
• Training tokens: 11159040 (x10 epochs)
• Vocabulary size: 50000
• Compute cost: 5.6935272480768e+16 FLOPs or ~5.4 NVIDIA A6000 GPU hours
