tam_taml_1000mb

Goldfish is a suite of monolingual language models trained for 350 languages. This model is the Tamil (Tamil script) model trained on 1000MB of data, after accounting for an estimated byte premium of 2.73; content-matched text in Tamil takes on average 2.73x 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: This language is available in Goldfish with other scripts (writing systems). See: tam_latn.

Note: tam_taml is an individual language code. It is not contained in any macrolanguage codes contained in Goldfish (for script taml).

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:
