Scope and Purpose

ChatGPT

ChatGPT is an advanced language model developed by OpenAI. Its primary purpose is to generate human-like responses in a chatbot-like conversation with users. ChatGPT has been trained on a vast amount of data from the internet, allowing it to understand and respond to a wide variety of topics and questions. The scope of ChatGPT is focused on engaging in conversation and providing relevant and helpful responses.

Bard

Bard, also developed by OpenAI, is another impressive language model with a distinct purpose. Unlike ChatGPT, Bard is designed specifically for creative writing, storytelling, and generating narrative content. Its scope revolves around generating high-quality text, such as poems, stories, and scripts, with a focus on literary expression. Bard's purpose is to assist users in enhancing their creative writing or even automate aspects of content creation.

Training Approach

ChatGPT

ChatGPT utilizes a method called Reinforcement Learning from Human Feedback (RLHF) for its training. Initially, human AI trainers engage in conversations and provide written responses as both the user and an AI assistant. These conversations, along with high-quality demonstrations from human AI trainers, form the dataset. Afterward, a reward model is created through comparison data, where two or more model-generated responses are ranked. Proximal Policy Optimization is used to fine-tune the model using this reward model, resulting in the final ChatGPT.

Bard

Unlike ChatGPT, which relies on supervised fine-tuning, Bard uses a method known as Reward Modeling with Proximal Policy Optimization. Initially, human AI trainers create a dataset of text passages in different writing styles. In this dataset, they imitate different prompts, allowing Bard to learn from their creative choices. Then, comparison data is collected by ranking multiple model responses according to quality. This data is used to create a reward model, which is used to further train Bard using Proximal Policy Optimization.

Level of Generality

ChatGPT

ChatGPT aims to provide responses that are generally helpful across a wide range of topics and conversational contexts. It has been designed to be a multipurpose conversational agent that can engage in various discussions and answer user queries. While it may not have the expertise of a subject matter expert, it can still generate informative and coherent responses on a broad spectrum of topics.

Bard

Bard, on the other hand, is more specialized in generating creative and narrative content. It excels in generating text that is engaging, expressive, and artistic. Bard understands narrative elements such as character development, plot progression, and pacing, enabling it to craft compelling stories, poems, and other forms of creative writing. Its focus on creative expressions makes Bard less suitable for general conversational purposes.

System Architecture

ChatGPT

ChatGPT follows a sequence-to-sequence architecture. It takes user messages as input, processes them, and generates corresponding model-generated responses. The input messages are tokenized and transformed into a fixed-length representation vector using an encoder model. This representation vector is then decoded by the model to generate a response. The model generates text word by word, taking into account the context of the conversation.

Bard

Similar to ChatGPT, Bard also uses a sequence-to-sequence architecture. It takes a prompt or starting sentence as input and generates a coherent and creative piece of writing. Bard's training process allows it to understand the context and generate text that follows the style and tone of the input prompt. Whether it's a sonnet, a screenplay, or a short story, Bard has the capability to generate text in various literary forms.
