Gemini vs ChatGPT: A Comprehensive Comparison in 2025

Generative AI has become a buzzword since OpenAI launched ChatGPT in November 2022. Although many looked to Google for advances in artificial intelligence (AI), OpenAI’s ChatGPT stole the show in the realm of generative AI by being the first-of-its-kind tool.

But in February 2024, Google Gemini made its grand entry, and just when everyone was expecting that it was just another addition to the AI family, this release made a lot of waves, but its big release at the Made for Google event in August 2024 did make a considerable mark.

The version of Gemini called Gemini Live runs on Android phones and lets people have free-flowing conversations on complex topics with their voice rather than typing away at the keyboard.    

While both tools fall under generative AI, a branch of artificial intelligence services, there are differences between the two. This article gives a comprehensive overview of the two tools. But first, let’s discuss what generative AI is, followed by a description of each tool, Gemini vs ChatGPT.

What is Generative AI?

Generative AI is a field of artificial intelligence that generates new content based on user queries. This content can be text, video, image, audio, and 3D models. Generative AI uses neural networks to analyze and identify patterns in existing data to create original content.  

From marketers and software developers to product designers and students, people from all walks of life use top AI tools like ChatGPT and Google Gemini for various purposes. These best AI tools allow them to access unique content in no time.

You can generate a poem, an article, a website code, and a lot more. In other words, they generate human-like responses to user input and queries.

However, these generative AI tools based on large language models have certain limitations, too. For instance, ChatGPT clearly states that the chatbot can give factually incorrect, biased, and outdated information. Gemini also concedes that it may not always be right and can even provide offensive output.   

Notwithstanding these limitations, ChatGPT gained a whopping one million users within five days of its launch – the fastest-ever score across all digital platforms created so far.  

Before we compare Gemini vs ChatGPT, let’s explain each platform briefly. 

What is Gemini?

Gemini is Google’s large language model (LLM). Now, you want to know what an LLM is. It’s the system that underpins the types of AI tools you’ve probably seen and interacted with on the internet. For example, GPT-4 powers ChatGPT-4o, OpenAI’s free chatbot, and ChatGPT Plus, which is a paid-for upgrade. 

However, Gemini is more than just an AI model; it’s also the new name and identity for its chatbot, previously known as Bard. In other words, Google has streamlined things by referring to both the underlying model and the chatbot itself as Gemini.

In addition, there’s a free Gemini app for Android now, and Gemini can supplant Google Assistant on your Android phone.

On iOS, Gemini is available within the Google app. There is also a free version of Google Gemini that is accessible through any browser on the internet. 

What is ChatGPT?

ChatGPT is OpenAI’s generative AI chatbot that performs almost the same functions as Gemini. It was launched in November 2022 and has since gained immense popularity. It employs deep learning, NLP, and large language models to interact with users in real time. 

Moreover, ChatGPT is trained on a vast dataset from the internet with billions of parameters. OpenAI has really exciting plans for ChatGPT. The company is planning to enhance its capabilities so that it can better respond to changing user needs.

It also wants to provide updates so that the tool can have better platform compatibility and improved features. 

What Happened to Google Bard? 

Nothing happened; Google just changed the name of Bard, and now it’s Gemini. The company continues to bring all things into a single, easy ecosystem. You can still access Gemini on the old bard.google.com, but it will redirect you to gemini.google.com. 

Gemini vs ChatGPT

ChatGPT is an AI language model developed by OpenAI and supported by a multiyear partnership with Microsoft. GPT stands for Generative Pre-trained Transformer, a state-of-the-art language model architecture that utilizes deep learning techniques, specifically a transformer-based neural network.   

The model is trained on vast amounts of text data, such as books, articles, and websites, to learn patterns, grammar, and contextual relationships within the language. The chatbot currently uses GPT-3.5. However, the premium version, called ChatGPT Plus, uses the more advanced GPT-4 model. Gemini is an advanced chatbot capable of creating better chunks of information.

On the other hand, ChatGPT is good at generating content with only a single text prompt.   

Gemini is a large language model, also known as a conversational AI or chatbot, created by Google AI. Gemini is trained on a massive dataset of text and code and can generate text, translate languages, write different kinds of creative content, and answer your questions informally.   

Gemini is based on LaMDA (Language Model for Dialogue Applications), a neural network-based language model. It’s trained on a vast dataset – it is 137 billion parameters in size. According to Google, the language model uses deep learning and is currently under development. However, it excels at conversational AI.   

Significant Differences Between ChatGPT and Gemini

Many people wonder which language model is a better generative AI chatbot. We have analyzed the two according to different benchmarks, including text processing and generation abilities, training dataset and underlying technology, internet access, ability to respond like humans, the accuracy of responses, interface and user-friendliness, and pricing.  

The major difference between the two platforms is the data sources that can be utilized to train the LLMs, which also power them. Gemini is excellent for research purposes, while ChatGPT excels at writing.

The differences can be best evaluated based on conversational AI vs generative AI. Generative AI vs. Conversational AI is Gemini vs. ChatGPT.  

1. Text Processing & Generation  

Text processing, summarization, generation, and translation are some of the major tasks modern AI chatbots like Gemini and ChatGPT perform. Gemini is more popular when it comes to conversational AI. However, if you talk about text summarization or generation, ChatGPT takes the prize.   

It is an excellent tool for generating human-like text like essays, poems, song lyrics, etc. Therefore, ChatGPT is a better tool for natural language processing techniques, as it can perform various textual-level roles.  

2. Training Dataset & Underlying Technologies  

Both chatbots employ neural networks called transformers; these networks perform sequential input processing. However, their training datasets are not the same; in fact, there are significant differences.  

OpenAI’s trainers scraped the web to create an extensive textual dataset using the data on the internet. To make it, they fed hundreds of thousands of books, documents, articles, etc.  

On the other hand, the team at Google AI used Infiniset to train Gemini. It is designed explicitly to enable conversational AI and human-like responses. Gemini is better at having robust conversations with its users, sounding much more natural than ChatGPT.  

Gemini can understand the intent behind a user’s questions and the nuance of context in a conversation, thanks to a hierarchical clustering of high-level concepts and topics. Its trainers designed it so that its responses are super-authentic and imitate human speech so precisely that it is difficult to tell them apart from a human’s.   

3. Internet Access  

Another key difference between the Gemini and ChatGPT lies in internet access. The variance between the two AI-powered chatbots is that Gemini can access internet data in real-time, while ChatGPT has internet data only until September 2021. This considerable difference gives Gemini a clear advantage over ChatGPT since the latter does not know the events after the cut-off date.

Moreover, Gemini also presents search results from the internet if you click the Google it button; ChatGPT has no such feature.  

4. Human-like Response

Generative AI chatbots are often judged against their ability to sound like humans. In this case, owing to Infiniset (a conversational dataset), Gemini outperforms ChatGPT. It usually offers more human-like responses than ChatGPT and can imitate human speech more accurately than OpenAI’s brainchild ChatGPT.  

Also, ChatGPT can include images in responses. In generative AI vs ChatGPT, the two are distinct concepts capable of producing human-like responses. However, ChatGPT vs. generative AI reveals that both focus on producing content in general. 

5. Response Accuracy  

Response accuracy and authenticity are vital factors in a chatbot’s success as they help build trust and credibility in the eyes of the user. Both ChatGPT and Gemini fall short on this account. However, Gemini is constantly learning new information through the internet, which also makes it more susceptible to peddling fake news as real.  

ChatGPT also gives factually incorrect information at times. This makes the use of these AI-enabled chatbots risky. This is one of the reasons why many leading AI and tech industry thought leaders, including the billionaire Elon Musk, called for a pause in AI development.   

6. Interface & User-friendliness  

Judging an application’s interface can often be a subjective endeavor. While some people think Gemini’s white background and clean interface make it better, others believe ChatGPT’s darker background is more appealing. Gemini allows users to edit questions, while ChatGPT does not, so you have to wait for the model to generate a response before asking another query. Both chatbots allow users to upvote or downvote a response.  

7. Pricing  

Both chatbots are currently freely available to all as they are in the experimentation stage. However, ChatGPT offers a premium version for roughly $20/month.   

Sum Up

To sum it up, both chatbots are excellent tools. So, is ChatGPT better than Gemini? No one can answer that. In some fields, such as user-friendliness, human-like responses, and updated information, Gemini seems to outperform ChatGPT. On the other hand, ChatGPT is a much better option for text processing, summarization, and generation.

Gemini is free as of now, but ChatGPT terminates the free account whenever it wants, asking users to switch to ChatGPT Plus. Your business requirements and goals can determine the tool that suits you best.
