FinBERT

FinBERT (ProsusAI/finbert) is a BERT model further pretrained on a large financial corpus (Reuters TRC2) and fine-tuned on the Financial PhraseBank for three-way sentiment classification of financial text: positive, neutral, negative. Published in 2019, it became the default baseline for finance NLP, widely reported to beat general models on financial sentiment benchmarks.

A decade-old architecture by current standards, it remains in heavy practical use for earnings-call analysis, headline scoring, and market-signal pipelines because it is small, fast, and well understood. The Hugging Face release is the canonical checkpoint most downstream work builds on.
