LLMs like GPT are heavy and costly (and BERT are LLMs too, params can up to like 1.5B). For niche problems like classification on a small domain, BERT like models are much better, cheaper. You don't need all knowledge gen AI LLM has. I have seen many companies using DeBERTa or RoBERTa for text classification, not using GPT/LLaMA.
