1. Bard vs ChatGPT at a glance

Before we dive deeper into comparing Bard vs ChatGPT, let’s start with a quick overview of the two chatbots.

ChatGPT: the conversational companion

ChatGPT, powered by OpenAI’s remarkable GPT 3.5 architecture, has emerged as a versatile conversational companion, revolutionizing how we interact with AI-powered chatbots. ChatGPT can offer observations on complex problems, engage in casual conversation, or even help spur creativity (with the right prompts).

With its impressive language capabilities, ChatGPT can provide insightful answers, imitate different writing styles, and hold engaging conversations across various topics.

It has found its home in customer support chatbots, virtual assistants, and any application where interactive and engaging text-based conversations are essential.

To master the basics, check out our step-by-step guide on how to use ChatGPT.

How does ChatGPT work?

ChatGPT, like other models based on the GPT (Generative Pre-trained Transformer) architecture, works through pre-training and fine-tuning on a massive amount of text data. 

ChatGPT was initially trained on a large and diverse corpus of text from the internet, with an information cutoff point in 2021.

During this pre-training phase, the model learned grammar, vocabulary, and general knowledge to predict the next word in a sentence. It built a deep understanding of language by capturing patterns and relationships between words and phrases.

ChatGPT utilizes the Transformer architecture, a neural network architecture that excels at processing data sequences, making it well-suited for natural language understanding and generation tasks.

After pre-training, the model is fine-tuned for specific tasks to make it more useful and safe for real-world applications. Fine-tuning involves training the model on a more narrow dataset that is carefully generated with human reviewers following guidelines provided by OpenAI.

These reviewers review and rate model outputs for various inputs to help the model learn appropriate responses.

When you use ChatGPT, it takes your input text and processes it through its trained neural network. It responds by predicting the most likely next word or phrase based on the patterns it learned during pre-training and fine-tuning.

The model can generate text one word at a time, and this process continues until it decides to stop based on the context and a defined stopping criterion.

It’s important to note that both Bard and ChatGPT employ safety mechanisms to prevent harmful or inappropriate content. These mechanisms filter out or reject outputs that violate content guidelines.

However, they are imperfect, and there can be challenges in striking the right balance between safety and the model’s ability to generate creative and useful responses.

ChatGPT’s user interface

ChatGPT utilizes a “conversational” UI, which presents a stream of questions and answers as if you were chatting to a friend on a messaging app. This is opposed to a visual interface, which would present information in various graphics, icons, and other imagery. 

Conversational UIs have existed for some time (you may remember the Microsoft Office assistant “Clippy”, launched in 1997), but the limitations of AI have meant that—up until now—conversational interfaces have led to underwhelming user experiences.

In ChatGPT’s case, with its strikingly human-like (and often witty) responses, the conversational UI works fantastically for inputting prompts.

Bard: the accurate wordsmith

Bard is an experimental, multilingual chatbot developed by Google and launched in the spring of 2023. Bard can assist with writing needs, math problems, and even coding. 

Named after William Shakespeare (often called The Bard), Bard is pitched as a creative content generator, offering poetry, creative writing, and storytelling services.

Bard’s unique selling point, however, is its accuracy. Unlike ChatGPT, Bard draws live information from the internet, meaning it needs to fill in the gaps or “hallucinate” less than GPT models trained on old data.

How does Bard work?

Bard currently uses Google’s cutting-edge PaLM 2 language model. This is a bold move, as most popular AI chatbots today, such as ChatGPT and Bing Chat, rely on models from the GPT series. 

PaLM 2 is significantly larger than OpenAI’s free architecture, boasting up to 340 billion parameters compared to GPT-3.5’s 175 billion. This impressive scale enables PaLM 2 to draw from masses during training.

PaLM’s two knowledge base contains information from millions of documents that it can reference during tasks. In contrast, ChatGPT relies solely on the patterns and examples from its training data.

Bard’s user interface

Like ChatGPT, Bard’s UI presents a vertical flow of questions and answers, together with a list of past conversations on the left-hand side.

As Bard is integrated with other Google apps, a few more buttons and icons surround the screen. 

This familiar interface, combined with the distinct lack of ChatGPT’s subversive humor, leaves Bard feeling like a functional workplace tool rather than interacting with a magical being.
