Large language models, such as transformer-based architectures, have achieved state-of-the-art results in various NLP tasks, including language translation, sentiment analysis, and text summarization. These models are typically trained on massive amounts of text data and require significant computational resources. However, with the increasing availability of open-source libraries and frameworks, it has become more accessible to build and train large language models from scratch.
