ChatGPT is a transformer, which is a neural network architecture that is primarily designed for sequence-to-sequence tasks, such as machine translation, text summarization, and chatbots. The Transformer's key innovation is its self-attention mechanism, which allows the model to weigh the importance of different input elements relative to each other. But a Transformer is not the only language model around. Another model, BERT (Bidirectional Encoder Representations from Transformers) is built on top of the Transformer architecture and is specifically designed for natural language understanding tasks, such as sentiment…
