In a world where artificial intelligence (AI) technologies are developing at a breakneck pace, two industry heavyweights, Google and OpenAI, are in a fierce battle to dominate the AI chatbot market. With the recent launch of the long awaited Google Bard it’s time to compare this newcomer with the proven skills of the popular ChatGPT.

In this article, we will analyze the main differences between these two platforms and examine their respective strengths and weaknesses.

ChatGPT vs Google Bard, what are the differences?

Google Bard

Google Bard is a chatbot developed by Google Research, capable of generating creative texts such as poems, stories, essays and songs. It uses a transform model trained on various text sources and takes into account user input and context.

Google Bard is a standalone tool that is not yet integrated with other applications. In the future, it may be integrated with the Chrome browser and its Chromium derivatives. Google also plans to open Google Bard to third-party developers. The main difference between the two is the language models used: Google Bard uses Google’s LaMDA model, while ChatGPT uses the GPT-3.5 and GPT-4 model.

ChatGPT is a chatbot capable of conversing naturally with humans, developed by OpenAI. It uses a transform model trained on a large corpus of conversations and can adapt to different personalities and topics.

It is particularly appreciated for its ability to answer direct questions and write creatively, despite some accuracy and plagiarism issues. It is integrated into various applications and services, such as the Bing search engine, Microsoft Teams, Edge and Microsoft Office applications. In the future, the Opera browser also plans to integrate ChatGPT.

The difference between Google Bard and ChatGPT

While Google Bard is based on the PaLM (Parallel Language Model) technology, ChatGPT uses the GPT-4 model developed by OpenAI.

While the two models are similar in terms of power and capabilities, there are subtle differences in the way they generate responses and interact with the user.


To compare Google Bard and ChatGPT, we will evaluate several key aspects such as:

  • Relevance, quality and accuracy of responses
  • Ease of use
  • Customization options
  • Cost and availability

Accuracy of Google Bard and ChatGPT

Both chatbots indicate that the accuracy of their responses should not be taken at face value. Nevertheless, Google Bard should have an advantage by having access to real-time information.

  • When asked the question “How many fans attended the 2022 World Cup in Qatar?”, Google Bard gave accurate numbers, while ChatGPT could not provide up-to-date information.
  • On non-topic data, such as “How long would it take to drive to the sun?”, Google Bard gave complete details, while ChatGPT provided a disappointing answer.

Creativity of Google Bard and ChatGPT

It’s harder to test these tools for the quality of their creative output. Both chatbots were asked to compose a short poem about chatbots in the style of William McGonagall. ChatGPT proved to be better at creative tasks than Google Bard.

Relevance and quality of answers

In our comparative tests, ChatGPT seems to slightly outperform Google Bard in terms of the relevance and consistency of the answers provided. However, both systems are able to generate highly contextual and informative responses. It should be noted that performance may vary depending on the knowledge area and complexity of the question being asked.

Ease of use

In terms of ease of use, both platforms offer an intuitive and easy-to-learn interface for users. However, Google Bard benefits from tight integration with other Google services and applications, which can be an advantage for users already familiar with the Google ecosystem.

Personalization options

Both systems offer customization options, allowing developers to tailor the chatbot’s behavior to the specific needs of their application or service. However, ChatGPT seems to offer a slightly wider range of options, especially in terms of fine-tuning the model and control over the responses generated.

Cost and Availability

Although Google Bard is currently only available to a select few users, it is expected to be rolled out gradually to all users in the near future. As for ChatGPT, it is already widely available and competitively priced. It will be interesting to see how Google positions its offering in terms of cost and accessibility compared to OpenAI.

The rivalry between Google Bard and ChatGPT highlights the intense competition in the AI chatbot market. Despite subtle differences in terms of underlying technology and response quality, it’s clear that both platforms are highly capable and promising. However, ChatGPT seems to maintain a slight edge in terms of response relevance and personalization options, while Google Bard benefits from integration with the Google ecosystem. The choice between these two solutions will ultimately depend on specific user needs and technology ecosystem preferences.

ChatGPT or Google Bard : Which to choose?

The decision between the two will depend more on user intent than preference.

  • Accuracy: Google Bard is the winner for factual, real-time information.
  • Creativity: ChatGPT produces more creative responses and is better for writing.
  • Security and safety: ChatGPT uses a reactive approach to security, while Google Bard is more proactive.
  • Ease of Use: Both tools are easy to use, but Google Bard lacks follow-up suggestions to prompts.

Both platforms have imperfections, which is normal for a new technology. However, widespread use and the feedback it generates will help accelerate the development of both models.

Tools like Bard and ChatGPT will transform the way we work, rest and play, marking the beginning of a technological revolution whose impacts are largely yet to be determined.
