Gemini vs. ChatGPT: Which is Better and What’s the Difference?

In the world of chatbots, two solutions are capturing all the attention: Google Gemini (ex-Bard) and ChatGPT.

But which is better? In this article, we look at Gemini vs. ChatGPT to determine their major capabilities and differences.

Our comparison includes an overview of each solution, a head-to-head comparison detailing their unique selling points, and a test of how they each responded to certain prompts.

Key Takeaways

  • The release of ChatGPT back in November 2022 kickstarted a wave of hype around generative AI, which has seen ChatGPT usage reaching 100 million weekly active users.
  • Gemini has replaced Bard as Google’s flagship AI model, which launched back in March 2023 and initially cost the company $100 million due to a factual error.
  • Bard rebounded to become one of the most popular and user-friendly alternatives on the market, achieving 340 million total visits according to data collected by SimilarWeb.
  • ChatGPT and Gemini are the most famous AI content generators, although the list of popular free AI writers is continuously growing.

Gemini vs. ChatGPT: How Do They Work?

How to Use Gemini?

Gemini is a free chatbot and multimodal large language model (LLM) created by Google and released in February 2024, in which users can interact with text, image, or audio input. Gemini is connected to the internet and can answer questions, generate content, summarize text, write code, and solve math problems.

It’s worth noting that Gemini is an upgrade to Bard (released in March 2023), which was trained on data scraped from the internet, including webpages, books, and articles.

This includes Common Crawl, a collection of over 250 billion web pages; Infiniset, a curated dataset designed to improve its dialogue capabilities; Wikipedia, an online encyclopedia, and user conversations.

Gemini is notable as a product because it’s designed to perform better at coding, logical reasoning, and following instructions. Its use of Google’s text-to-image model Imagen 2 also gives it the ability to create images on demand.

So, How Does Gemini Work?

Gemini uses various technologies, including machine learning, natural language processing (NLP), and natural language generation (NLG) to analyze its training data and user inputs.

The chatbot scans text included in its training data with NLP to learn patterns in natural language. Once the user enters an input, Gemini then uses NLP and NLG to provide a response that matches their request. The response is generated by predicting the words most likely to address their prompt.

How to Use ChatGPT?

ChatGPT is a large language model (LLM) developed by OpenAI that was originally launched in November 2022. Users can interact with ChatGPT online on the OpenAI website. The free version supports text input, whereas paid versions like ChatGPT Plus support image and voice input.

It’s worth noting that the standard version of ChatGPT features a fine-tuned version of OpenAI’s GPT 3.5 LLM. Like Bard, GPT 3.5 uses various technologies, including machine learning, NLP, and NLG to process and respond to user input.

A more powerful version of ChatGPT, which uses the GPT-4 language model, is also available and comes with paid product versions.

ChatGPT was also trained on a large dataset of web pages, books, and articles, most notably with the Common Crawl dataset, and is also trained on user conversations.

However,  it’s important to highlight that ChatGPT has a knowledge cutoff of April 2023

and does not know of any events after this date.

How Does ChatGPT Work?

The chatbot processes natural language in its training data and uses it to predict relevant responses to user input. Users can enter a query via text, voice, or image.

Users can ask ChatGPT questions in natural language, generate content, translate text, write code, solve math problems, or even generate images (with a paid plan like ChatGPT Plus or ChatGPT Enterprise with the DALL-E 3 integration).

Paid subscribers have the option to switch between GPT 3.5 and GPT-4 directly in the user interface.

Gemini Pro is available for free.

Gemini Ultra is available by upgrading to Gemini Advanced via the Google One AI Premium Plan.

Paid plans start at $19.99 per month.

Gemini Advanced vs. ChatGPT Plus

With the launch of Gemini Advanced, both Google and OpenAI have paid subscription plans for upgrades to their consumer chatbot models. In this section, we’re going to take a look at how each service stacks up.

Gemini Advanced is available as part of the Google One AI Premium plan for $19.99 per month. Purchasing this subscription means that Gemini will use the Ultra model and give access to 2TB of cloud storage.

It’s worth mentioning that AI Premium subscribers will be able to use Gemini with Gmail, Docs, Slides, and Sheets in the future.

On the other hand, ChatGPT Plus costs $20 per month. For this price, users not only gain access to GPT-4, but also an integration with DALL-E 3, which enables them to create images directly within the chatbot.

In addition, users also have access to GPTs – custom versions of ChatGPT, which can be shared on the GPT Store (they can also access other users’ custom GPTs). Users also gain priority access to new features as they emerge.

As for each vendor’s current offerings, the key differentiator is that with Gemini Advanced, you get access to the high-powered ultra model and cloud storage.

With ChatGPT Plus, you gain GPT-4, a DALL-E 3 integration, and custom GPTs. Overall, we feel that ChatGPT Plus has the advantage because it gives you access to more features.

Gemini vs ChatGPT 4: A Short Test

To get a feel for the capabilities of each tool firsthand, Techopedia entered a series of prompts to see how Gemini and ChatGPT would respond.

For the purposes of this comparison, we used the GPT-4 version of ChatGPT versus the free Gemini Pro version of Gemini. This enabled us to evaluate how the base version of Gemini compares against OpenAI’s flagship model.

It’s important to note that this test is highly subjective – and the results generated in each example could be improved further with some prompt engineering and adding more context about what type of content the user wants to generate.

The test includes a comparison of:

  • Text summarization
  • Content generation
  • Brainstorming
  • Graph creation
  • Image creation

Text Summarization

To test the two chatbots’ text summarization capabilities, we asked each tool to write a short summary of William Shakespeare’s famous play Macbeth.

Gemini’s response was as follows:

Text Summarization

Gemini produced a short summary that was difficult to read in places (e.g. Macbeth “encounters witches who prophecy his rise to king”) but provided a basic high-level overview.

Now let’s look at ChatGPT’s response:

ChatGPT’s response

ChatGPT provided a more detailed response to our prompt as well as a more logical summary of Macbeth. While it could have been shorter, it was much better than the response provided by Gemini.

So, in our text summarization test, ChatGPT delivered a more thorough and engaging summary.

Content Generation

The next capability we decided to test was content generation. In this exercise, we opted to test each tool’s ability to generate emails due to their rigid formatting.

We did this by entering the prompt “Write a cold email selling an SEO marketing service.”

Gemini’s response was as follows:

Gemini’s response

This prompt generated a basic email template, but the quality was poor and would likely require significant edits from a human marketer before it could provide value.

Now let’s look at ChatGPT’s response:

ChatGPT’s response

ChatGPT’s response took noticeably longer to generate, but the quality of the email template it generated was well beyond Gemini’s, even though the paragraphs were too long in places.

As a result, ChatGPT gets the nod again.

Brainstorming

Many users use language models as brainstorming tools, so we tested these capabilities as part of this comparison.

To do this, we wanted to test what ideas each tool could come up with if asked to produce an outline for a blog post on social media marketing. The results on Gemini were as follows:

Gemini

We felt that the outline generated by Gemini was extremely generic and far below what you could expect from a content professional or industry insider, though it provided some basic structure.

Here is what ChatGPT generated in response to the prompt:

ChatGPT generated in response

ChatGPT’s outline was much less developed than Gemini’s, with each section lacking the array of talking points that Gemini highlighted.

While neither tool offered a compelling outline, Gemini got the edge for offering a more developed outline that could easily be improved by a content professional.

Graph Creation

Both Gemini and ChatGPT had the ability to create graphs (we tested this capability as part of a previous comparison, so we decided to test this again by asking Gemini and ChatGPT to create a graph of historical World War 2 events.

The output on Gemini was as follows:

The output on Gemini was as follows:

As you can see, the tool declined to create a graph for us. While the initial prompt was vague, we did use it in the past to get Bard to produce a graph output. This is shown in the prompt below:

This is shown in the prompt below:

In this sense, Gemini’s failure to produce a graph in this instance was very disappointing and a step back from Bard.

In contrast, ChatGPT’s response was much better:

ChatGPT’s

Not only did the presentation of the graph look much better than Bard’s, but it also provided an accurate timeline of key WWII events.

So in the confines of this test, ChatGPT’s graph creation appeared to be head and shoulders above Gemini’s.

The Bottom Line

Based on all factors, ChatGPT showed better results than a free version of Gemini Pro in our short test. We would recommend Gemini based on its ability to respond to simple questions succinctly and quickly. However, ChatGPT offers a broader range of functionality and a more powerful long-form output.

At the same time, while ChatGPT can produce outputs quickly, waiting for it to generate responses felt noticeably more tedious than with Gemini, probably due to the lack of a “skip response” button.

As it stands, Gemini is more than Google’s version of ChatGPT, it is a useful research assistant in its own right, but it remains to be seen whether it can unseat OpenAI’s chatbot as the dominant tool on the market.
