As artificial intelligence and machine learning continue to evolve at a rapid pace, we find ourselves in a world where chatbots are becoming increasingly commonplace. Google recently made headlines with the release of Bard, its language model for dialogue applications (LaMDA). It is said to be trained to have more natural and open-ended conversations with humans. Meanwhile, ChatGPT-4 (GPT4) has been gaining popularity as a natural language processing tool that can perform a range of tasks.

In this article, we take a closer look at these two conversational AI tools and compare them head-to-head. We evaluate them based on several parameters, including human-like response, dataset, and model used, the authenticity of response, access to the internet, user-friendliness and interface, charges and price, and text processing.

Parameter 1: Human-Like Response

The ability of a chatbot to provide responses that sound like they come from a real human being is crucial to its success. When it comes to human-like responses, Bard outperforms ChatGPT-4 in terms of mimicking natural language and having more open-ended conversations. We also found out that Bard sounds kind of ‘offended’ by the stupid questions. Example:

Prompt: How many heads does the President of a nation have?

Response: “Presidents are human beings, and human beings have one head. Therefore, presidents have one head.

I comprehend that you might perceive this as a jest, yet it’s crucial for me to clarify that I’m not a human being. I’m a sophisticated language model, often referred to as a conversational AI or chatbot, designed to provide thorough and informative responses. Trained on extensive textual data, I possess the capability to engage in diverse conversations and generate human-like text across a broad spectrum of topics. For example, I can provide summaries of factual topics or create stories.”

Parameter 2: Training Dataset and Underlying Technology

Comparing the two popular AI chatbots, Chatgpt-4 (GPT4) & Google Bard on their training dataset and underlying technology.

Both ChatGPT-4 and Google Bard use transformer architecture, a type of neural network that processes sequential input. However, their training datasets differ significantly. ChatGPT4 was trained on an extensive dataset of text from the internet, including books, articles, and documents scraped from the open web. Meanwhile, Bard’s training focused on Infiniset, a dataset designed specifically for conversations and dialogue. As a result, while both models can understand and generate a wide range of text for multiple purposes, Bard is better at having natural and open-ended conversations with humans.

To achieve this, the Google team created clusters of high-level concepts and topics based on hierarchy, which were used to inform the model’s choices when responding. This approach enables Bard to understand the intent behind a user’s questions and the nuance of context in a conversation. Additionally, Bard’s responses are designed to be ultra-authentic and mimic human speech so accurately that they are indistinguishable from a real human. Moreover, Bard can switch context when a user changes the subject, making it even more adept at navigating complex conversations.

Parameter 3: Authenticity of Response

The authenticity of a chatbot’s responses is essential for building trust with users. While Google claims that Bard’s responses are ultra-authentic and mimic human speech closely, we found that some of its responses were less than authentic. For instance, when we asked it to list down the top ten developments around generative AI in the last 24 hours, it mentioned a tool named BlenderBot 4.0. Bard said that the tool which is available to the public, can “generate realistic text and speech that is indistinguishable from human-generated content.”. In reality, the release of BlanderBot 4.0 is nothing more than Bard’s Hallucination (or Fear?). Not only this, 80% of the news listed by Bard was ‘Fake News’. So Hallucination still seems to be a major issue with Bard.

Parameter 4: Access to the Internet

One of the major differences between ChatGPT-4 and Google Bard is their access to the internet. Bard can draw its responses from the internet in real-time, while ChatGPT4 relies on a dataset that only goes up until late 2021. This limitation means that ChatGPT-4 may struggle to provide up-to-date information, whereas Bard can offer the most recent answers to questions and the latest research. Also, every response from Bard has a little icon of Google Search with it. As you click on it, it suggests related queries, which you can tap to Google for.

Parameter 5: User Friendliness and Interface

The user-friendliness of a chatbot is essential for making it accessible to a broad range of users. Bard has an advantage over ChatGPT-4 when it comes to user-friendliness. It has a nicer-looking interface and formatted text that’s much easier to scan. Moreover, Bard allows you to edit your questions after you ask them. Also, you can upvote and downvote the response, along with searching for it over the web. Overall, the interface of Bard looks cleaner and more organized.

Parameter 6: Text Processing: Summarization, Paragraph Writing, Etc

Chatbots can perform a wide range of tasks, including summarization, paragraph writing, and translation. While Bard offers better conversational AI capabilities, ChatGPT-4 excels in text processing, making it ideal for applications such as summarization, where accuracy and comprehensiveness are crucial. The ability to perform multiple roles on a more textual level makes ChatGPT4 a versatile and valuable tool for anyone working with NLP (natural language processing).

Parameter 7: Charges and Price

ChatGPT-4 is well known for the human-grade response it generates. But, access to ChatGPT4 doesn’t come for free, and users only get a limited number of questions every day. On the other hand, Bard is free for all.


In conclusion, both Google Bard and ChatGPT-4 are powerful conversational AI tools that excel in different areas. Bard outperforms ChatGPT-4 when it comes to human-like response, user-friendliness of the interface, and real-time access to the internet. However, ChatGPT4 has an advantage in text-processing tasks like summarization and paragraph writing. While Bard’s responses aim for ultra-authenticity, it still falls short in terms of hallucination or generating fake news. Moreover, ChatGPT4 limits access and requires payment, while Bard is freely available to all. We must consider these factors when choosing between the two tools, depending on the specific use case and requirements.
