FinBert vs. ChatGPT: Unveiling the Superiority in Financial Text Analytics

 A study by JPMorgan and Queen's University highlights FinBert's dominance over ChatGPT in financial text analysis. FinBert excels in sentiment analysis and arithmetic reasoning, showcasing its specialization in finance, while ChatGPT falters in domain-specific tasks.

In a groundbreaking study by JPMorgan and Queen's University, the remarkable FinBert, fine-tuned on intricate financial domain data, has showcased its supremacy over ChatGPT in the realm of financial text analytics.

Comparing the capabilities of Gpt-3.5-turbo and GPT-4 (both with 8k tokens) to FinBert, a battery of tests including Arithmetic Reasoning, News Classification, Sentiment Analysis, and Named Entity Recognition were conducted. The results unveiled the distinct advantages of FinBert in the financial landscape.

•Sentiment Analysis Success: FinBert excels in sentiment analysis tasks pertaining to financial texts. Understanding nuanced expressions and comprehending the influence of news on investors is paramount in financial sentiment analysis. FinBert's domain-specific design grants it a competitive edge without requiring extensive adaptation or fine-tuning.

•Struggles in Financial NER and Sentiment Analysis: In financial named entity recognition (NER) and sentiment analysis, where profound domain-specific knowledge is indispensable, ChatGPT and GPT-4 face challenges. Their inability to grasp the intricacies of financial terminologies becomes evident in these domains.

This comparative analysis juxtaposes these models against finely-tuned counterparts tailored explicitly for the financial sector, like FinBert and FinQANet. The results underscore that while Large Language Models (LLMs) exhibit potential, they are not yet at par with their specialized counterparts. This study marks the initial step towards further refinement.

The disparity between state-of-the-art generative language models and domain-specific proficiency persists, but it also heralds a promising opportunity for enhancement. As Rajiv Shah, a machine learning engineer at Hugging Face, aptly puts it, "A domain-specific model like FinBERT is more accurate for finance tasks than GPT-4." The future holds exciting possibilities for the intersection of AI and finance.
