What are the differences between Bard AI and Chatgpt"s language models, GPT-2, GPT-3 & GPT-4?

The knowledge required to elucidate on the contrast between Bard AI by Google and ChatGPT by OpenAI, as well as their respective variations: GPT-2, GPT-3, and GPT-4. Bard AI operates on the BERT architecture, a system that stands for Bidirectional Encoder Representations from Transformers. The objective of BERT is to tackle natural language processing tasks, like text classification and question-answering, via the training of a transformer-based model that can handle massive amounts of text data. Bard AI, in particular, has been fine-tuned for the purpose of dialogue applications, and it can manage multi-turn conversations. In contrast, ChatGPT functions based on the GPT architecture, a model that stands for Generative Pre-trained Transformer. The GPT model is also transformer-based, but it is optimized for generating text, such as language translation and text completion. ChatGPT has the ability to generate coherent and fluent text, which makes it an ideal option for dialogue applications in which it can generate responses to user input. The GPT-2, GPT-3, and GPT-4 are different variations of ChatGPT, each possessing a progressively higher degree of model complexity and training data size. GPT-2 has 1.5 billion parameters and was trained on a dataset of 40 GB of text data, while GPT-3 has 175 billion parameters and was trained on a dataset of 45 TB of text data. Currently, GPT-4 is under development, and the details of its parameters and training data size have not been disclosed yet. One of the major differences between Bard AI and ChatGPT/GPT variations is their primary focus. Bard AI is designed for dialogue applications, while ChatGPT/GPT variations are optimized for text generation tasks. Additionally, their training data size and model complexity differ, with GPT-3 and GPT-4 being significantly larger than Bard AI. To conclude, Bard AI and ChatGPT/GPT variations are advanced language models that excel in different natural language processing tasks. Bard AI is fine-tuned for dialogue applications, while ChatGPT/GPT variations are optimized for text generation tasks. The choice of which to use is ultimately dependent on the specific needs and requirements of the application.
