Google Bard vs ChatGPT: Usage

Language Support

One of the key differences between Google Bard and ChatGPT is their language support. While Google Bard is limited to US English, ChatGPT offers support for 26 different languages. This makes ChatGPT a more versatile option for users who require communication in languages other than English.

User Distribution

Both Google Bard and ChatGPT have a significant user base in the United States. Approximately 62.6% of users for Google Bard are from the US, while ChatGPT has around 15% of its users from the US.


When it comes to availability, ChatGPT outshines Google Bard. ChatGPT is accessible in 162 countries, allowing users from various parts of the world to engage with the chatbot. On the other hand, Google Bard is officially available only in the US and the UK.

User Engagement

User session duration is a vital metric in assessing user engagement. ChatGPT demonstrates a higher average user session duration of 8.44 minutes, while Google Bard lags behind with an average session duration of 3.19 minutes. This suggests that users tend to engage with ChatGPT for longer periods, indicating higher user satisfaction.

Google Bard vs ChatGPT: Technicals

To understand the technical aspects of Google Bard and ChatGPT, let’s delve into their neural network architecture and pre-training data.

Neural Network Architecture

Both ChatGPT and Google Bard utilize the Transformer neural network architecture. However, there are differences in the training data size and parameters. ChatGPT, running on GPT 3.5, is trained on 300 billion words and consists of 175 billion parameters. On the other hand, Google Bard runs on LaMDA, which was trained on an impressive Infiniset dataset comprising 1.56 trillion words and 137 billion parameters. It is expected that GPT-4 will have even more parameters than GPT 3.5.

Pre-training Data

The pre-training data cut-off is another area where Google Bard and ChatGPT differ. ChatGPT has a more recent pre-training data cut-off of 2021, while Google Bard’s cut-off is 2019. This means that ChatGPT’s language model has access to more up-to-date information, allowing it to provide users with real-time data. In terms of data storage size, ChatGPT utilizes 570 GB for pre-training data, while Google Bard requires 750 GB.

Google Bard vs ChatGPT: Financials

Let’s now explore the financial aspects of using Google Bard and ChatGPT, including the cost analysis and subscription plans.

Cost Analysis

According to estimates by UBS, for every search query triggered by Google’s AI chatbot Bard, Alphabet incurs incremental costs ranging from $0.003 to $0.028 on top of the base search cost of approximately $0.003 per query. On the other hand, a report published by SemiAnalysis suggests that OpenAI bears a cost of $0.0036 for each query made in ChatGPT. These costs reflect the expenses associated with running these advanced AI language models.

Subscription Plans

While both Google Bard and ChatGPT offer free access to their chatbot services, ChatGPT provides an additional subscription plan called “Plus.” For $20 per month, ChatGPT Plus subscribers gain access to advanced models like GPT 3.5 Turbo and GPT-4, along with other benefits. As of now, there is no paid subscription plan available for Google Bard.


In this comprehensive comparison of Google Bard and ChatGPT, we have explored their usage, technical aspects, and financial considerations. While Google Bard offers real-time information and has a vast training data size, ChatGPT excels in language support and user engagement. Ultimately, the choice between Google Bard and ChatGPT depends on individual requirements and preferences. We hope this comparison has provided you with valuable insights into these AI chatbots and helps you make an informed decision.
