Compare ChatGPT and Google Gemini - Which tool stands out more?

ChatGPT and Google Gemini are two AI tools that are causing a stir in the market with many useful features for users. Both have a free service, a paid subscription enhancement service with similar features. Not to mention, in terms of interface and usage, there is not much difference. So what is the difference between these two tools? Let's find out together now.

What is ChatGPT?
ChatGPT, the standout AI chatbot in 2023, attracted 1 million users in just five days after its launch on November 30, 2022. Based on the Generative Pre-trained Transformer (GPT) model, ChatGPT analyzes data to generate feedback for the user and provides an interface to the AI language model. As of May 2024, the free version uses GPT-4o, with the option of GPT-3.5, while paid versions such as ChatGPT Plus, ChatGPT Team, and ChatGPT Enterprise provide access to GPT-4 with extended features. GPT-4 is considered the most advanced GenAI model, although Google Gemini Advanced is a notable competitor.
ChatGPT has many applications such as content creation, text summarization, language translation, and research support. ChatGPT Voice version allows users to chat via voice on iOS and Android. The free version is available on browsers and mobile devices, while ChatGPT Plus offers seamless access and integration with Dall-E 3, a text-to-image model. ChatGPT Team and ChatGPT Enterprise serve businesses, with additional features like larger message volumes and faster response times. ChatGPT Enterprise also provides unlimited high-speed GPT-4 access and advanced analytics and administration tools.
What is Google Gemini?

Google Gemini is Google's GenAI model, developed by DeepMind and launched as Bard in March 2023, before changing its name to Gemini in February 2024. Gemini Advanced version, available from May 2024, replaces Gemini 1.5 Pro and offers big data analytics for 1 million tokens.
Gemini works like other smart assistants, providing answers based on information from Google services. Integrating into Google Search and Google Workspace apps like Docs, Gmail, and Sheets, Gemini is available on both Android and iOS. Image creation has been paused for improvements, but Gemini Advanced is still available through the Google One AI Premium plan for $19.99 monthly, including 2 TB of storage. Gemini Pro, the free version, is suitable for simple tasks.
Differences between ChatGPT and Gemini
1. Training model

ChatGPT is developed based on OpenAI's GPT-3.5 and GPT-4 models. Meanwhile, Gemini comes in three versions: Gemini Pro for multiple tasks, Gemini Ultra for very complex tasks, and Gemini Nano for mobile devices. The Gemini Advanced version, built on Gemini Pro 1.5, provides faster and more advanced performance than the free version of Gemini.
2. Data source

The biggest difference between ChatGPT and Gemini is the data source used to train the language models. ChatGPT, uses the GPT-4o model, based on pre-defined and collected data, valid until October 2023. In contrast, Gemini uses data collected from the internet in real time, which is regulated and tailored to specific topics like coding or the latest scientific research.
3. User experience
ChatGPT users can log in with any email account and use the API to integrate ChatGPT into other software applications. Although there is no built-in storage option, users can copy and paste answers into another application. ChatGPT does not support sending images, videos, or links, and does not have internet search capabilities. This feature is part of a partnership between OpenAI and Microsoft, allowing ChatGPT to be used across Windows applications such as Word and Excel.

Gemini offers more options to users. Gemini Pro's interface allows users to like or dislike responses, modify the size or tone of responses, and export responses to Google Docs or Gmail. Users can also upload images, however, the image creation feature is paused for improvements. Gemini also has a "review other drafts" option, allowing users to view alternative versions of answers.
4. Data storage and privacy
ChatGPT stores all chats and queries, allowing users to review previous conversations. While users can delete responses and conversations, OpenAI can continue to use this information to train its models, leading to privacy concerns. OpenAI collects personal information such as email addresses, phone numbers, and device information, and may share data with third parties or law enforcement agencies if necessary.

In contrast, Gemini stores chat in a user's Google account for 18 months, but users can adjust the storage period. Chats can also appear in searches, creating privacy concerns. Google collects data about conversations, location, feedback and usage information, and uses it to develop and improve the service. Users can delete information from their Google account or delete their account if they wish.
Which tool is better?
Currently, the race between GenAI models is very exciting. Therefore, both OpenAI and Google continuously update their technology. While Google is actively developing Gemini, especially when ChatGPT is the tool released first, competing and catching up is one of the prerequisites. Below are some reviews from experts when comparing these two tools:

- Ethan Mollick, associate professor of AI research at the Wharton School of the University of Pennsylvania conducted tests to compare Gemini Advanced against GPT-4 and concluded that Gemini Advanced is the first advanced AI model that can compete with GPT-4. He said each model has its own strengths and weaknesses compared to the competition such as Chat GPT which uses more sophisticated code and is better at verbal tasks. While Gemini is better at explaining and finding information.
- Bernard Marr - author of Generative AI in Practice also stated that ChatGPT is designed to be more conversational while Gemini processes information and automates tasks more effectively.
Both ChatGPT and Gemini are far from perfect, and their developers admit that. Both even have notes at the bottom of the screen like “ChatGPT can make mistakes. Check important information" which means that the information displayed may not be accurate, consider checking the response to ensure the effectiveness and objectivity of the information.
It can be said that choosing the right tool ultimately depends on the user's personal needs and preferences. We can test the free versions of both tools to find the most suitable one.
