%description
Provides access to word predictability estimates using large language
models (LLMs) based on 'transformer' architectures via integration with
the 'Hugging Face' ecosystem <https://huggingface.co/>. The package
interfaces with pre-trained neural networks and supports both
causal/auto-regressive LLMs (e.g., 'GPT-2') and masked/bidirectional LLMs
(e.g., 'BERT') to compute the probability of words, phrases, or tokens
given their linguistic context. For details on GPT-2 and causal models,
see Radford et al. (2019)
<https://storage.prod.researchhub.com/uploads/papers/2020/06/01/language-models.pdf>,
for details on BERT and masked models, see Devlin et al. (2019)
<doi:10.48550/arXiv.1810.04805>. By enabling a straightforward estimation
of word predictability, the package facilitates research in
psycholinguistics, computational linguistics, and natural language
processing (NLP).
