Gemini AI Pro vs ChatGPT Plus: Detailed Comparison

Now, getting straight to it, Google’s Gemini, formerly known as Bard, was relaunched as “Gemini” with a powerful new AI model, Gemini 2.5, featuring deep research capabilities.

This aligns with what OpenAI’s ChatGPT Plus subscription has been offering: a deep research function.

While ChatGPT has been a pioneer in revolutionizing the tech world with its advanced artificial intelligence capabilities, others have caught up quickly.

Now, Google isn’t far behind and has an answer to OpenAI in the form of Gemini Advanced.

What Is Gemini Flash & Pro?

In January 2024, Google announced rebranding its AI chatbot, Bard, as Gemini and Gemini Advanced. After this, the AI tool underwent another change, with the company renaming their subscription plans to Gemini Pro and Gemini Ultra.

Currently, these models run under the names Gemini 2.5 Flash and Gemini 2.5 Pro.

I am guessing this move was necessary to eliminate confusion between Bard and Gemini, as Gemini is at the core of Google’s AI developments.

Gemini Pro, Google’s latest and largest AI language model, is available at a price of $19.99/month, which offers more than just access to a powerful AI assistant.  

Things you get with a Gemini Pro subscription:

1. Flow access for their signature Veo 3 AI model to create AI videos.
2. NotebookLM for research and writing
3. 2TB of Google One storage and benefits worth $9.99/month.
4. Ability to execute complex tasks.
5. Gemini in Gmail and Docs.

Gemini Limitations:

The current Gemini limitations are the rare hallucinations and the inaccuracy of the results provided. Another limitation, depending on the plan you are signed up for, would be the subscription limits to using a few tools like Veo 3, Whisk, and more.

What Is ChatGPT Plus?

ChatGPT still holds the crown as the most preferred AI chatbot for users, with over 180.5 million monthly users. ChatGPT Plus is OpenAI’s paid subscription plan that gives access to its most advanced language model, GPT 4o.

This subscription comes with a bunch of key features that are exclusive to ChatGPT Plus. 

Things you get with ChatGPT Plus:

1. AI image generation with DALL-E, and GPT 4o
2. Custom GPT creation
3. GPT store access 
4. Over 1000+ plugins
5. Image-to-text, text-to-voice, and voice-to-text prompts.

ChatGPT Plus Limitations

ChatGPT Plus limitations are mainly faced in its usage, with the message limits of 160 messages with GPT-5 every 3 hours. Apart from this, the individual models have their restrictions too, but they do not affect the user experience in any way.

With the good and the bad of both tools laid out, let’s begin by reviewing them side-by-side.

Gemini Advanced vs ChatGPT – Major Differences

Gemini Advanced and ChatGPT Plus are both available at a starting price of $19.99/month and $20/month. Apart from the differences between the creators and organizations, Gemini Advanced and ChatGPT Plus have noticeable differences. 

Let’s go through them one by one.

1. Unique Features

Both AI chat assistants have some features that the other doesn’t. For example, Gemini provides users with access to Google’s search engine, whereas ChatGPT Plus utilizes Bing and SearchGPT to deliver its internet-powered results.

Gemini Advanced distinct features:

• MMLU benchmark score of 90%
• Gemini Advanced can access Google for its web results
• Enhanced Coding abilities
• Better control over tone, style, and focus. 
• Can be selected as the primary voice assistant.
• Powerful image editing on select Pixel phones.

ChatGPT Plus distinct features: 

• MMLU benchmark score of 86.4%
• Can be shared between workspaces
• Powerful data analysis with graphical representation.
• Custom GPT model creation. 

2. Compatibility

Users can use both these AI chatbots over a wide range of devices. Both Gemini Pro and ChatGPT Plus are also available in the Apple App Store and Google Play Store. 

In recent news, with the new Google Nano Banana update, Google Gemini has surpassed the ChatGPT app on both Google and Apple app stores as the #1 app to be downloaded.

Gemini Advanced (Pro) Compatibility:

What’s interesting here is the direction Google is taking with its Gemini and how a Google user utilizes this AI language model. 

With the new Gemini App, you can integrate Gemini directly as your phone assistant, replacing “Google Assistant.” Google had already hinted at the use of AI in its future updates, and with the introduction of Gemini Pro, it appears to have begun. 

ChatGPT Plus compatibility:

ChatGPT is available as a mobile app, but it remains a separate service. You cannot use ChatGPT Plus as a default assistant, as you can use Gemini Advanced.

But ChatGPT Plus can assist you in using live audio and images pretty well with its mobile app!

3. AI Image Generation

ChatGPT recently announced the addition of a feature to generate hyperrealistic images that come very close to the quality of Midjourney-generated images with its GPT-4o image generation model.

Google, on the other hand, introduced the Nano Banana AI, which raised the standards even higher, with the world adopting the hot trends of AI image generation, like creating 3D figurines using Nano Banana AI.

Generating images with both is as simple as entering a standard text prompt, unlike some complex AI image generators, where you need to define and set a list of parameters to get an output. 

To test the image generation abilities of both, I provided an identical prompt to both AI chat assistants. Let’s see the difference. 

Prompt Used: “Generate an image of an evil octopus trying to take over a city. He’s sitting inside a spaceship overlooking a city.”

Gemini Advanced AI image generation

Gemini, with its new Nano Banana AI image generation, nails the image out of the park and offers the quickest image generation of ChatGPT Plus.

Generating an image is not complex and only requires a well-framed prompt to achieve the desired results.

Gemini Pro Nano Banana AI-generated Image: 

ChatGPT Plus AI image generation

ChatGPT Plus has been my current favorite when it comes to generating AI images with ease and up to perfection. It generates high-quality AI images and accurately understands the prompt. 

The downside of ChatGPT Plus is the lack of on-the-go editing features. However, to compensate, it can understand the editing requirements through text and provide an edited image accordingly. Also, it is slower than Gemini to generate an image.

DemandSage Bonus: One such AI chatbot comes very close to providing the editing features of Gemini Advanced and ChatGPT Plus – Microsoft Copilot. It offers editing features on the go with upscaling, aspect ratio options, and more.

We have covered the 17 best AI image generators in our other work, where we tested them against each other to generate an image from the same prompt. However, few could generate images within the chat the way ChatGPT and Gemini can.

4. Comparing Writing Abilities

AI’s role in writing has been long-standing. AI writers and software help users write catchy puns and complex research papers, and even help generate fully optimized content for search engines.

But how do Gemini Advanced and ChatGPT Plus perform in this field? 

To get started, I took help from a prompt suggestion displayed by Gemini Advanced and ran it with both Gemini Advanced and ChatGPT Plus. Additionally, Gemini Advanced provides suggestive prompts to help you get started generating an image, code, or text.

In order to test their writing abilities, I ran this prompt:

”Write an opening scene for a fantasy fiction novel set in a steampunk 18th century. Be descriptive and historically accurate. Avoid anachronism. The scene should involve Eleanor, a young natural philosopher, on a quest to understand the nature of knowledge and learning. Write in the style of Jane Austen. Build mystery throughout the scene and end with an unexpected revelation.”

Gemini Advanced generated result:

“Miss Eleanor Pemberley possessed a formidable mind, far too formidable for the provincial world in which she found herself confined. Though she lacked the formal trappings of the university, Eleanor’s attic study held more texts of natural philosophy than the meager shelves of the local vicarage. The delicate whirring and ticking of gears filled the room, the product of her latest project: a small clockwork beetle whose gleaming brass wings flittered under the glow of her oil lamp.  Yet, despite her brilliance, a sense of gnawing uncertainty always seemed to shadow her. There was an order to the world, a pattern waiting to be deciphered, and she was determined to crack the code.”

ChatGPT Plus generated result:

“In the dim light of dawn, Eleanor stood at the edge of the bustling city of London, her gaze fixed upon the horizon where the modern marvels of steam and iron carved a new skyline amidst the ancient stones. The air was filled with the scent of coal and the distant sound of machinery, a testament to the age of invention that had transformed the 18th century into a canvas of human ingenuity.

Eleanor, with her curious mind and insatiable thirst for knowledge, found herself at the crossroads of the old world and the new. A natural philosopher by passion, she was driven by a quest that was as much personal as it was intellectual—to unravel the mysteries of knowledge and learning, a pursuit that had often left her isolated in a society that viewed her interests with skepticism, if not outright disdain.”

Both Gemini and ChatGPT pass the test here, and can get pretty creative in their writing.

5. Coding Abilities

ChatGPT Plus has been regarded as a good option for generating and fixing code. But it certainly is not the best. Gemini Advanced, on the other hand, boasts its “Advanced Coding Abilities.”

It is necessary to test the coding abilities of both, as it is the current favorite way for many users to use an LLM (Large Language Model). 

According to this Google Deep Mind Gemini report for Gemini Ultra (Ultra 1.0), it has achieved a HumanEval score of 74.4% for Python problems. 

This is in comparison to GPT-4, which could only fetch a HumanEval score of 67% for Python coding tasks. View this official GPT 4 research to learn more. 

Here’s a visual representation of generating complex Python code:

Prompt used: ‘’Create a Python Code for Bubble Sort”

Gemini Advanced Python Code:

def bubble_sort(arr):
"""Sorts an array using the Bubble Sort algorithm.

Args:
    arr: The array to be sorted.
"""

n = len(arr)

# Traverse through all array elements
for i in range(n - 1):
    # Last i elements are already in place, no need to iterate through them
    for j in range(0, n - i - 1):

        # Swap if the element found is greater than the next element
        if arr[j] > arr[j + 1]:
            arr[j], arr[j + 1] = arr[j + 1], arr[j]

ChatGPT Plus Python Code:

def bubble_sort(arr):
    n = len(arr)
    # Traverse through all array elements
    for i in range(n):
        # Last i elements are already in place
        for j in range(0, n-i-1):
            # Traverse the array from 0 to n-i-1. Swap if the element found is greater
            # than the next element
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr

Both ChatGPT Plus and Gemini Advance were able to give out the required Python code quickly. Try it out yourself to see how it works.

Bottom Line – A Gemini AI Pro Subscription is Better Than ChatGPT Plus

If you have to choose one, you have to subscribe to the Gemini AI Pro subscription. It’s a no-brainer. With the same price as ChatGPT Plus, you get 2TB of cloud storage, AI access to daily required features like Gmail and Docs, and a lot more.

Google has won the comparison with Gemini 2.5 Pro and the new Nano Banana image model, developing its Gemini AI for users and allowing broad access to Gemini across Google services.

After the recent Google 2025 I/O, the future of Gemini looks promising and multidimensional. Yet, if you need to invest your $20 in an AI tool right away, you can surely go ahead with Google Gemini!
