A Critical Review of Large Language Models: Sensitivity, Bias, and the Path Toward Specialized AI

Abstract: This paper examines the comparative effectiveness of a specialized compiled LLM and a general-purpose model like OpenAI's GPT-3.5 in detecting SDGs within text data. It presents a critical review of LLMs, addressing challenges related to bias and sensitivity. The necessity of specialized training for precise, unbiased analysis is underlined. A case study using a company descriptions dataset offers insight into the differences between the GPT-3.5 and the specialized SDG detection model. While GPT-3.5 boasts broader coverage, it may identify SDGs with limited relevance to the companies' activities. In contrast, the specialized model zeroes in on highly pertinent SDGs. The importance of thoughtful model selection is emphasized, taking into account task requirements, cost, complexity, and transparency. Despite the versatility of LLMs, the use of specialized models is suggested for tasks demanding precision and accuracy. The study concludes by encouraging further research to find a balance between the capabilities of LLMs and the need for domain-specific expertise and interpretability.
