Developed by OpenAI, the AI tool has gone through many changes since it was first announced. While a free version exists, paid versions are also available known as ChatGPT Plus and ChatGPT Enterprise.
A free version of ChatGPT (GPT-3.5) is available for anyone to use on the ChatGPT website. All you have to do is sign up to get a login, and you can be mining the depth of the AI model in seconds. ChatGPT is also available on Android and Apple devices
A more advanced version of ChatGPT, known as ChatGPT-4, is also now available, but only to paid subscribers.
The AI has achieved a lot since it was announced, being embraced by huge companies, rejected by schools and used by millions of users each day. Met with equal parts controversy and praise, it is a truly divisive tool.
Now, with plenty of competitors (such as Google Bard), ChatGPT is having to constantly improve and offer new features, the most recent of which is the introduction of Dall-E 3 – an included image generator, capable of operating with ChatGPT to make your image dreams come true.
So how does the tool work? Why is it so controversial? And how do you actually use ChatGPT? With the help of AI researchers and experts, we’ve answered these questions and more below in this detailed guide to OpenAI’s most famous tool.
What is GPT-3, GPT-4 and ChatGPT?
GPT-3 (Generative Pretrained Transformer 3), GPT-3.5 and GPT-4 are state-of-the-art language processing AI models developed by OpenAI. They are capable of generating human-like text and have a wide range of applications, including language translation, language modelling, and generating text for applications such as chatbots.
GPT-3.5 is one of the largest and most powerful language-processing AI models to date, with 175 billion parameters.
GPT-3.5 gives a user the ability to give a trained AI a wide range of worded prompts. These can be questions, requests for a piece of writing on a topic of your choosing or a huge number of other worded requests.
Above, it described itself as a language-processing AI model. This simply means it is a program able to understand human language as it is spoken and written, allowing it to understand the worded information it is fed, and what to spit back out.
What can ChatGPT do?
With its 175 billion parameters, it’s hard to narrow down what GPT-3.5 does. The model is, as you would imagine, restricted to language. It can’t produce video, sound or images like its brother Dall-E 2, but instead has an in-depth understanding of the spoken and written word.
You can use ChatGPT-3.5 to:
Write essays
Write excel formulas
Write poems and movie scripts
Research topics and summarise content
Help you build a cover letter or CV
Write code
Plan a holiday
ChatGPT has a very wide range of abilities, everything from writing poems about sentient farts and cliché rom-coms in alternate universes, through to explaining quantum mechanics in simple terms or writing full-length research papers and articles.
While it can be fun to use OpenAI’s years of research to get an AI to write bad stand-up comedy scripts or answer questions about your favourite celebrities, its power lies in its speed and understanding of complicated matters.
Where we could spend hours researching, understanding and writing an article on quantum mechanics, ChatGPT can produce a well-written alternative in seconds.
It has its limitations and its software can be easily confused if your prompt starts to become too complicated, or even if you just go down a road that becomes a little bit too niche.
Equally, it can’t deal with concepts that are too recent. World events that have occurred in the past year will be met with limited knowledge and the model can produce false or confused information occasionally.
OpenAI is also very aware of the internet and its love of making AI produce dark, harmful or biased content. Like its Dall-E image generator before, ChatGPT will stop you from asking the more inappropriate questions or for help with dangerous requests.
What can ChatGPT-4 do?
A more advanced version of ChatGPT, called ChatGPT-4 is now available for paid subscribers ($20/£16 a month).
Here are just a few tasks the latest version of the AI model of capable of:
Learn a language. You can talk to ChatGPT in 26 languages
Create recipes. ChatGPT-4 is able to recognise images – you can send ChatGPT a picture of ingredients and ask the AI to create a recipe
Describe images to blind people
How much does ChatGPT cost?
ChatGPT-3.5 is free and easy to sign up for and use, simply:
Head over to the ChatGPT website and create an account. You can sign-up using a Google, Microsoft or Apple account, or any email address.
Logging in will present you with a very simple page. You are offered some example prompts, and some information about how ChatGPT works.
At the bottom of the page is a text box. This is where you can ask ChatGPT any of your questions or prompts.
ChatGPT-4, a more advanced version of ChatGPT is now available, but is only available via a paid subscription of $20 (£16) a month.
Is there a ChatGPT app?
There is an official ChatGPT app which you can download for free on Apple and Android devices. Be sure to download the official ChatGPT app from Open AI – there any many similar apps available that may have limited functionality or a paywall.
Once downloaded and installed, simply log in with your OpenAI account to get going.
How is GPT-4 different to GPT-3.5?
In essence, GPT-4 is the same as its predecessor GPT-3.5. However, there are some new features that boost the software’s abilities.
Mainly, GPT-4 includes the ability to drastically increase the number of words that can be used in an input… up to 25,000, 8 times as many as the original ChatGPT model.
Equally, OpenAI has stated that the latest version of their technology makes fewer mistakes that they are calling ‘hallucinations’. Previously, ChatGPT could become confused, offering up a nonsensical answer to your question, or even inputting stereotypes or false information.
Additionally, GPT-4 is better at playing with language and expressing creativity. In OpenAI’s demonstration of the new technology, ChatGPT was asked to summarise a blog post only using words that start with the letter ‘g’. It also has a better understanding of how to write poetry or creative writing, but it is still by no means perfect.
On top of this, OpenAI also displayed the potential of using images to initialise prompts. For example, the team showed an image of a fridge full of ingredients with the prompt “What can I make with these products?”. ChatGPT then returned a step-by-step recipe.
While it wasn’t demonstrated, OpenAI is also proposing the use of video for prompts. This would, in theory, allow users to input videos with a worded prompt for the language model to digest.
Creating recipes with images is a clever use of the technology, but it is only the tip of how images could be used with ChatGPT. The company also demonstrated the ability to create a whole website that successfully ran JavaScript with just a handwritten sketch of a website.
As a tool to complete jobs normally done by humans, GPT-3.5 was mostly competing with writers and journalists. However, GPT-4 is being shown to have the ability to create websites, complete tax returns, make recipes and deal with reams of legal information.
On the face of it, GPT-3.5’s technology is simple. It takes your requests, questions or prompts and quickly answers them. As you would imagine, the technology to do this is a lot more complicated than it sounds.
The model was trained using text databases from the internet. This included a whopping 570GB of data obtained from books, web texts, Wikipedia, articles and other pieces of writing on the internet. To be even more exact, 300 billion words were fed into the system.
As a language model, it works on probability, able to guess what the next word should be in a sentence. To get to a stage where it could do this, the model went through a supervised testing stage.
Here, it was fed inputs, for example “What colour is the wood of a tree?”. The team has a correct output in mind, but that doesn’t mean it will get it right. If it gets it wrong, the team inputs the correct answer back into the system, teaching it correct answers and helping it build its knowledge.
It then goes through a second similar stage, offering multiple answers with a member of the team ranking them from best to worst, training the model on comparisons.
What sets this technology apart is that it continues to learn while guessing what the next word should be, constantly improving its understanding of prompts and questions to become the ultimate know-it-all.
Think of it as a very beefed-up, much smarter version of the autocomplete software you often see in email or writing software. You start typing a sentence and your email system offers you a suggestion of what you are going to say.
What does it mean when ChatGPT is at full capacity?
If you try to use ChatGPT and you receive the error message telling you it’s “at capacity”, it likely means that too many people are currently using the AI tool.
Essentially, the OpenAI servers can only handle so much traffic at any given time. If too many people are trying to access it at once, ChatGPT’s servers may buckle under the weight.
If you have encountered the “ChatGPT is at capacity right now” error message, you need to try again later. You can try to refresh the page and what have you, but time is the healer here.
What does ChatGPT stand for?
The ‘GPT’ in ChatGPT stands for Generative Pre-trained Transformer.
Can you use ChatGPT to write a CV?
ChatGPT won’t write a CV out of thin air for you, instead, you will need to prompt it with your relevant experience, what type of job you’re applying for, and potentially provide more information including pasting your old CV that needs updating or an example of one for a similar field.
ChatGPT: latest news
Dall-E integration
In September 2023, OpenAI announced that ChatGPT would be integrated with the latest version of Dall-E.
Dall-E is an AI art generator, made by ChatGPT creators OpenAI. It was the first of OpenAI’s projects to really blow up online and is the model that most AI art generators are based on. Now on its third generation, OpenAI has made the decision to pair the two models together.
For anyone who has ChatGPT Plus or Enterprise, this feature will be available. Images can be made via ChatGPT, and the model can even aid you in creating prompts and editing the images to better suit your needs.
It is yet to be announced whether this feature will later come to ChatGPT’s free tier but for now, it is remaining an exclusive feature for paying customers.
ChatGPT Enterprise
Along with the addition of ChatGPT Plus, OpenAI introduced another pay-to-use version of the tool known as ChatGPT Enterprise. This offers higher levels of security and privacy, unlimited higher-speed searches and a host of other features.
This version is intended for businesses looking to get more out of ChatGPT as a work tool. OpenAI has stated that it will not train on the data created by businesses.
A handful of the biggest Chinese tech firms have launched their own AI chatbots after receiving government approval.
The biggest of these is Ernie bot, an AI model developed by Baidu, China’s leading online search provider. Similar to ChatGPT, users can ask questions of Ernie bot, using prompts to research topics, summarise articles, and much more.
The Baidu app is currently available to download in the UK on Android and Apple devices. However, all text will appear in Chinese.
Experts warn AI risks our extinction
The heads of ChatGPT’s developer, OpenAI, have signed a statement (alongside many AI experts) warning of the need to address the human extinction risk associated with AI.
The statement reads: “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”
Members of the OpenAI team to sign the statement include its CEO, Sam Altman, and its chief scientist, Ilya Sutskever. The list of signatories also includes the CEO of Google DeepMind, many university professors and public figures such as Bill Gates.
Concerns for the future
A general apprehension has followed artificial intelligence throughout its history and things are no different with ChatGPT. Critics have been quick to raise the alarms over this technology, but now even those closest to it are utilising caution.
An open letter has been drafted calling for all AI labs to pause for at least six months on the development of systems more powerful than GPT-4. This would include OpenAI’s work on GPT-5 – the next version of technology ChatGPT will eventually run on.
This open letter has been signed by prominent AI researchers, as well as figures within the tech industry including Elon Musk, Steve Wozniak and Yuval Noah Harari.
This letter states that the pause should be public and verifiable, arguing that companies like OpenAI, Microsoft and Google are entering a profit-driven race to develop and release new AI models at a dangerous pace.
This comes at the same time as a report from Goldman Sachs that suggested 300 million full-time jobs could be impacted by AI systems like ChatGPT, escalating existing concerns around these platforms.
Where is GPT-4 being used?
GPT-3 was already being adapted by a lot of big companies, inputting the technology into search engines, apps and software, but OpenAI seems to be pushing GPT-4 even harder.
Microsoft’s Bing is the main user of the technology right now, but OpenAI has reported that the software is being used by companies like Khan Academy to help students with coursework and give teachers ideas for lessons.
Equally, the language-learning app Duolingo has got involved with something called ‘Duolingo Max’ with two features. One will help explain why your answer to a question was right or wrong, the other will set up role plays with an AI to play out language in different scenarios.
More companies are adopting this technology, including the payment processing company Stripe and customer service brand Intercom.
Are there any other AI language generators?
While GPT-3 has made a name for itself with its language abilities, it isn’t the only artificial intelligence capable of doing this. Google’s LaMDA made headlines when a Google engineer was fired for calling it so realistic that he believed it to be sentient.
Google launched a chatbot powered by LaMDA called Bard on March 21, 2023. It’s similar to ChatGPT but benefits from having access to up-to-date information.
There are also plenty of other examples of AI language software out there created by everyone from Microsoft to Amazon and Stanford University. These have all received a lot less attention than OpenAI or Google, possibly because they don’t offer fart jokes or headlines about sentient AI.
Most of these models are not available to the public, but OpenAI has begun opening up access to GPT-3 during its test process, and Google’s LaMDA is available to selected groups in a limited capacity for testing.
Where ChatGPT thrives and fails
The GPT-3.5 software is obviously impressive, but that doesn’t mean it is flawless. Through the ChatGPT function, you can see some of its quirks.
Most obviously, the software has a limited knowledge of the world after 2021. It isn’t aware of world leaders that came into power since 2021, and won’t be able to answer questions about recent events.
This is obviously no surprise considering the impossible task of keeping up with world events as they happen, along with then training the model on this information.
Equally, the model can generate incorrect information, getting answers wrong or misunderstanding what you are trying to ask it.
If you try and get really niche, or add too many factors to a prompt, it can become overwhelmed or ignore parts of a prompt completely.
For example, if you ask it to write a story about two people, listing their jobs, names, ages and where they live, the model can confuse these factors, randomly assigning them to the two characters.
Equally, there are a lot of factors where ChatGPT is really successful. For an AI, it has a surprisingly good understanding of ethics and morality.
When offered a list of ethical theories or situations, ChatGPT is able to offer a thoughtful response on what to do, considering legality, people’s feelings and emotions and the safety of everyone involved.
It also has the ability to keep track of the existing conversation, able to remember rules you’ve set it, or information you’ve given it earlier in the conversation.
Two areas the model has proved to be strongest are its understanding of code and its ability to compress complicated matters. ChatGPT can make an entire website layout for you, or write an easy-to-understand explanation of dark matter in a few seconds.
Where ethics and artificial intelligence meet
Artificial intelligence and ethical concerns go together like fish and chips or Batman and Robin. When you put technology like this in the hands of the public, the teams that make them are fully aware of the many limitations and concerns.
Because the system is trained largely using words from the internet, it can pick up on the internet’s biases, stereotypes and general opinions. That means you’ll occasionally find jokes or stereotypes about certain groups or political figures depending on what you ask it.
For example, when asking the system to perform stand-up comedy, it can occasionally throw in jokes about ex-politicians or groups who are often featured in comedy bits.
Equally, the models love of internet forums and articles also gives it access to fake news and conspiracy theories. These can feed into the model’s knowledge, sprinkling in facts or opinions that aren’t exactly full of truth.
In places, OpenAI has put in warnings for your prompts. Ask how to bully someone, and you’ll be told bullying is bad. Ask for a gory story, and the chat system will shut you down. The same goes for requests to teach you how to manipulate people or build dangerous weapons.
Will ChatGPT be banned in schools?

While a number of companies are looking to implement ChatGPT, in other areas it is quickly being banned.
In New York, the city’s education department has ruled that the tool will be forbidden across all devices and networks in New York public schools.
There are two main reasons for this decision. First, the chat model has been shown to make mistakes and isn’t always accurate, especially with information from the past year.
Secondly, there is a real risk of plagiarism with students able to get ChatGPT to write their essays for them.
While New York is the first place to publicly ban the software, it is likely to be a decision made elsewhere too. However, some experts have argued that this software could actually enhance learning.
“ChatGPT and other AI-based language applications could be, and perhaps should be, integrated into school education. Not indiscriminately, but rather as a very intentional part of the curriculum. If teachers and students use AI tools like ChatGPT in service of specific teaching goals, and also learn about some of their ethical issues and limitations, that would be far better than banning them,” says Kate Darling, a research scientist at the MIT Media Lab.
“But, in absence of resources for teachers to familiarise themselves with the technology, schools may need to enact some policies restricting its use.”
In this way, Darling emphasises a belief held by many in the world of artificial intelligence. Instead of ignoring or banning it, we should learn how to interact with it safely.
This is an opinion mirrored by Sam Illingworth, an associate professor in the department of Learning Enhancement at Edinburgh Napier University.
“AI is very much here to stay, so why try to fight it? These are tools that our students will be using in the workforce, so it seems very strange to say don’t use them for three years, pretending they don’t exist for now,” says Illingworth.
“These are things that have the potential to reduce workload and improve efficiency, our responsibility as educators is to decide how to utilise it.”
Artificially intelligent eco-systems
Artificial intelligence has been in use for years, but it is currently going through a stage of increased interest, driven by developments across the likes of Google, Meta, Microsoft and just about every big name in tech.
However, it is OpenAI which has attracted the most attention recently. The company has now made an AI image generator, a highly intelligent chatbot, and is in the process of developing Point-E – a way to create 3D models with worded prompts.
In creating, training and using these models, OpenAI and its biggest investors have poured billions into these projects. In the long-run, it could easily be a worthwhile investment, setting OpenAI up at the forefront of AI creative tools.

How about users? I’m a European who will be able to take advantage of all these DMA-related benefits. I already know I don’t want sideloading on iPhone (or Android, for that matter). But interoperability seems like the dumbest requirement of the DMA, a feature I don’t want to take advantage of in WhatsApp or any competing instant messaging app that might be labeled a gatekeeper.
Meta’s explanation of how WhatsApp interop will work is also the best explanation for the unnecessary interoperability requirement. Why go through all this trouble to fix something that wasn’t broken in the first place?
What is interoperability?
Meta explained in a detailed blog post all the work behind making WhatsApp and Facebook Messenger compatible with competing chat apps that ask to be supported.
Tech. Entertainment. Science. Your inbox.
Sign up for the most interesting tech & entertainment news out there.
That’s what interop hinges on. First, a WhatsApp rival must want their app to work with Meta’s chat platforms. Even if that’s achieved, it’s up to the WhatsApp/Messenger user to choose whether to enable the functionality.
Meta says it wants to preserve end-to-end WhatsApp encryption after interop support arrives. It’ll push WhatsApp and Messenger’s Signal encryption protocol for third-party chat apps. Other alternatives can be accepted if they’re at least as good as Signal.
How will it work?
Meta has been working for two years to implement the changes required by the DMA. But things will not just work out of the box starting Thursday. A competing service must ask for interop support and then wait at least three months for Meta to deploy it.
It might take longer than that for WhatsApp and Messenger to support that service. Rinse and repeat for each additional chat app that wants to work with WhatsApp.
That’s a lot of work right there, both for Meta and WhatsApp competitors. I can’t see how any of this benefits the user. The interop chat experience isn’t worth it to me. Here’s what you’ll get in the first year. Because yes, the DMA has specific requirements in place for what features interop chats should offer:
Interoperability is a technical challenge – even when focused on the basic functionalities as required by the DMA. In year one, the requirement is for 1:1 text messaging between individual users and the sharing of images, voice messages, videos, and other attached files between individual end users. In the future, requirements expand to group functionality and calling.
Thankfully, the DMA also focuses on privacy and security. That’s why WhatsApp and Messenger will focus on ensuring that chats remain end-to-end encrypted. I’ll note that Messenger end-to-end encryption started rolling out months ago, and it might not be available in all markets.

Meta’s blog does a great job explaining what’s going on under the hood with interop chats between WhatsApp and third-party apps. It underlines all the massive work and resources Meta is deploying for this.
I’m actually kind of in awe of Meta’s willingness to comply with these DMA provisions. All this effort makes me wonder what Meta can gain from the whole interoperability thing. Maybe the endgame is converting even more users to WhatsApp and Messenger, but I digress. After all, it’s not like Meta could avoid complying with the DMA.
I’ll also say that Meta doesn’t seem to restrict interoperabiltiy to the European Union, as Apple does with iPhone sideloading. Or, at least, restrictions aren’t the focus of this blog, though the title clarifies it’s about chats in Europe: “Making messaging interoperability with third parties safe for users in Europe.”
The obvious warning
While Meta also explains how encryption and user authentication will work, it acknowledges that it’s not in full control. Therefore, it can’t promise the user the same level of security and privacy for Whatsapp interop chats as Whatsapp-to-Whatsapp chats:
It’s important to note that the E2EE promise Meta provides to users of our messaging services requires us to control both the sending and receiving clients. This allows us to ensure that only the sender and the intended recipient(s) can see what has been sent, and that no one can listen to your conversation without both parties knowing.
While we have built a secure solution for interop that uses the Signal Protocol encryption to protect messages in transit, without ownership of both clients (endpoints) we cannot guarantee what a third-party provider does with sent or received messages, and we therefore cannot make the same promise.
[…] users need to know that our security and privacy promise, as well as the feature set, won’t exactly match what we offer in WhatsApp chats.
If you care about WhatsApp interoperability should read the entire blog post at this link. Then promptly disable the feature once WhatsApp informs you that interop support is ready.
It’s March 7th, the big deadline day for the Digital Markets Act (DMA). The law came into effect on Thursday,…
This is a hugely environmentally destructive side to the tech industry. While it has played a big role in reaching net zero, giving us smart meters and efficient solar,it’s critical that we turn the spotlight on its environmental footprint. Large language models such as ChatGPT are some of the most energy-guzzling technologies of all. Research suggests, for instance, that about 700,000 litres of water could have been used to cool the machines that trained ChatGPT-3 at Microsoft’s data facilities. It is hardly news that the tech bubble’s self-glorification has obscured the uglier sides of this industry, from its proclivity for tax avoidance to its invasion of privacy and exploitation of our attention span. The industry’s environmental impact is a key issue, yet the companies that produce such models have stayed remarkably quiet about the amount of energy they consume – probably because they don’t want to spark our concern.
Google’s global datacentre and Meta’s ambitious plans for a new AI Research SuperCluster (RSC) further underscore the industry’s energy-intensive nature, raising concerns that these facilities could significantly increase energy consumption. Additionally, as these companies aim to reduce their reliance on fossil fuels, they may opt to base their datacentres inregions with cheaper electricity, such as the southern US, potentially exacerbating water consumption issues in drier parts of the world. Before making big announcements, tech companies should be transparent about the resource use required for their expansion plans.
Furthermore, while minerals such as lithium and cobalt are most commonly associated with batteries in the motor sector, they are also crucial for the batteries used in datacentres. The extraction process often involves significant water usage and can lead to pollution, undermining water security. The extraction of these minerals are also often linked to human rights violations and poor labour standards. Trying to achieve one climate goal of limiting our dependence on fossil fuelscan compromise another goal, of ensuring everyone has a safe and accessible water supply.
Moreover, when significant energy resources areallocated to tech-related endeavours, it can lead to energy shortages for essential needs such as residential power supply. Recent data from the UK shows that the country’s outdated electricity network is holding back affordable housing projects. This will only get worse as households move away from using fossil fuels and rely more on electricity, putting even more pressure on the National Grid. In Bicester, for instance, plans to build 7,000 new homes were paused because the electricity network didn’t have enough capacity.
In an era where we expect businesses to do more than just make profits for their shareholders, governments need to evaluate the organisations they fund and partner with, based on whether their actions will result in concrete successes for people and the planet. In other words, policy needs to be designed not to pick sectors or technologies as “winners”, but to pick the willing by providing support that is conditional on companies moving in the right direction. Making disclosure of environmental practices and impacts a condition for government support could ensure greater transparency and accountability. Similar measures could promote corporate accountability in global mineral supply chains, enforcing greater human rights compliance.
In navigating the intersection of technological advancement and environmental sustainability, policymakers are facing the challenge of cultivating less extractive business models. This is not just about adopting a piecemeal approach; it’s about taking a comprehensive systematic view, empowering governments to build the needed planning and implementation capacity. Such an approach should eschew outdated top-down methods in favour of flexible strategies that integrate knowledge at all levels, from local to global. Only by adopting a holistic perspective can we effectively mitigate the significant environmental impacts of the tech industry.
Ultimately, despite the unprecedented wave of innovation since the 1990s, we have consistently overlooked the repercussions of these advances on the climate crisis. As climate scientists anticipate that global heating will exceed the 1.5C target, it’s time we approach today’s grand challenges systemically, so that the solution to one problem does not exacerbate another.
When you picture the tech industry, you probably think of things that don’t exist in physical space, such as the…
OpenAI introduced ChatGPT in November 2022, sparking a tremendous amount of interest in artificial intelligence. ChatGPT gained so much attention that generative AI (GenAI) became a dominant theme in the tech world in 2023.
Microsoft backed OpenAI at the start of 2023 by pledging a multimillion-dollar, multiyear investment to accelerate OpenAI’s development of its AI technology.
Google made its GenAI move in March 2023 with Bard. In February 2024, Google rebranded Bard as Gemini when it debuted an improved version of the AI chatbot.
ChatGPT and Gemini are largely responsible for the considerable buzz around GenAI, which uses data from machine learning models to answer questions and create images, text and videos. OpenAI and Google are continuously improving the large language models (LLMs) behind ChatGPT and Gemini to give them a greater ability to generate human-like text.
GenAI is still rapidly evolving, and models don’t always return correct answers. Despite the common occurrence of AI hallucinations — wrong answers generated by AI — in both ChatGPT and Gemini, the tools are being adopted by businesses and consumers seeking to automate time-consuming tasks.
What is ChatGPT?
ChatGPT is the AI-powered chatbot that made GenAI the hot technology of 2023. According to OpenAI CEO Sam Altman, ChatGPT reached 1 million users within five days of its release on Nov. 30, 2022.
Generative Pre-trained Transformer, the model ChatGPT is based on, finds patterns within data sequences. Its AI language model produces responses to user queries and serves as the interface that lets users communicate with the language model. As of May 2024, GPT-4o is an available default in the free version of ChatGPT. Users can still choose to use GPT-3.5, which was the previous default. A more robust access to GPT-4o as well as GPT-4 is available in the paid subscription versions of ChatGPT Plus, ChatGPT Team and ChatGPT Enterprise. GPT-4 was generally considered the most advanced GenAI model when it became available, but Google Gemini Advanced provided it with a formidable rival.
Popular applications for ChatGPT include content generation of emails, social media posts and blogs; text summarization; language translation; code generation; learning and education; building virtual assistants; simulation and training; research assistance; and building games and other entertainment applications.
ChatGPT is multimodal, meaning users can use images and voice to prompt the chatbot. ChatGPT Voice — available on iOS and Android phones — lets users hold conversations with ChatGPT, which can respond in one of five AI-generated voices.
ChatGPT and ChatGPT Plus are targeted at individual users. The free version of ChatGPT is available through web browsers and mobile devices. Developers can also embed ChatGPT APIs in their software applications for their users to access.
ChatGPT Plus costs $20 per user, per month. The full version of GPT-4o, used in ChatGPT Plus, responds faster than previous versions of GPT; is more accurate; and includes features such as advanced data analysis. GPT-4o can also create more detailed responses and is faster at tasks such as describing photos and writing image captions. And while GPT-3.5 was only trained on data up to January 2022, GPT-4o has been trained on data up to October 2023.
Another advantage of a ChatGPT Plus subscription is that it guarantees ChatGPT access even during peak usage times. Response times for free ChatGPT are limited by bandwidth and availability. ChatGPT Plus also provides integrated access to OpenAI’s Dall-E 3 text to image GenAI model.
OpenAI sells ChatGPT Team and ChatGPT Enterprise to businesses. ChatGPT Team is available for $25 per user, per month billed annually. It includes everything in ChatGPT Plus but allows more messages during a defined time limit. It can also share GPTs with other workers, has a faster response time than ChatGPT Plus and includes an admin console. ChatGPT Enterprise has unlimited high-speed access to GPT-4; more advanced administration, customer support and analytics capabilities; expanded content windows for longer inputs; and has the fastest response time of all the ChatGPT versions. ChatGPT Enterprise pricing varies depending on usage.
What is Google Gemini?
Gemini is Google’s GenAI model that was built by the Google DeepMind AI research library. The Gemini AI model powered Google’s Bard GenAI tool that launched in March 2023. Google rebranded Bard as Gemini in February 2024, several months after launching Gemini Advanced based on its new Ultra 1.0 LLM foundation. In May 2024, Google first offered users of Gemini Advanced access to the newer Gemini 1.5 Pro model.
Gemini is designed to retrieve information as a simple answer, similar to the way smart assistants like Alexa and Siri work. It uses LLMs to reply to prompts with information it has already learned or can retrieve from other Google services.
Google Gemini is multimodal — it understands audio, video and computer code as well as text. Google has paused Gemini’s image generation feature because of inaccuracies, however. Google’s statement disclosing the pause pledged to re-release an improved image generation feature soon.
Gemini’s capabilities are integrated into Google’s search engine and available in Google Workspace apps such as Docs, Gmail, Sheets, Slides and Meet. Gemini for Google Workspace is the new name for Duet AI for Google Workspace, which was Google’s answer to the Microsoft Copilot AI assistant. Google Gemini is available through an app on Android phones and in the Google app on iOS.
Gemini Advanced is part of the Google One AI Premium plan subscription service that costs $19.99 per month in the United States. Google One AI Premium also includes 2 TB of storage.
Gemini Advanced is a more powerful AI version than Gemini Pro, which remains available for free. Gemini Advanced with Gemini Pro 1.5 provides a large context window of 1 million tokens, enabling analysis of larger data sets.
Google suggests Gemini Pro and its AI capabilities is the better choice for development, research and creation tasks, and if you’re looking for a free chatbot. It brings AI to simple tasks for personal use. For those willing to pay the subscription fee, Google recommends Gemini Advanced for professional applications, more demanding workflows, enhanced performance and more cutting-edge capabilities. Google Advanced will also include early access to new features.
Gemini Nano, another part of the Google Gemini family, is used in devices such as Google’s Pixel 8 Pro smartphones.

ChatGPT and Google Gemini have become increasingly similar. Both have a free service, a nearly identically priced subscription service, and similar interfaces and use cases. The differences are largely under the hood — in their language models.
They’re also used for many similar functions, and work by users typing in a query to get a response. Both raise privacy concerns about how user data can be used. However, they differ in their training models, data sources, user experiences and how they store data.
Training models
ChatGPT is built on OpenAI’s GPT-3.5 or GPT-4. Gemini has three sizes: Gemini Pro for a wide range of tasks, Gemini Ultra for highly complex tasks, and Gemini Nano for mobile devices. Gemini Pro 1.5, which powers the subscription Gemini Advanced version, is faster and more advanced than the model used for the free Gemini service.
Data sources
The main difference between ChatGPT and Gemini is the data sources used to train their LLMs. GPT-4o uses predefined data that goes up to October 2023. Gemini draws on data pulled from the internet in real time. It is tuned to select data chosen from sources that fit specific topics such as coding or the latest scientific research.
User experience
ChatGPT users can log onto the free ChatGPT with any email account. ChatGPT also includes an API that developers can use to integrate OpenAI LLMs into third-party software. It lacks a Save button, but users can copy and paste answers from ChatGPT into another application. It does have an Archive button that can list previous responses in ChatGPT’s left-hand pane for quick retrieval.
Because ChatGPT is text-based, it can’t include images, videos, charts or links in its answers. It also lacks the ability to search the internet.
Because of OpenAI’s close partnership with Microsoft, ChatGPT can be used through Windows apps such as Word, Excel, PowerPoint and Outlook. Also, Microsoft’s Copilot AI assistants use the GPT-4 language model.
Gemini Pro’s interface gives users a chance to like or dislike a response, opt to modify the size or tone of the response, share or fact-check the response, or export it to Google Docs or Gmail. Gemini also has a “review other drafts” option that shows alternate versions of its answer. Gemini also lets users upload images, but its ability to create images is on hold until Google improves that feature.
Data storage and privacy
Both ChatGPT and Google Gemini store user data.
ChatGPT stores all prompts and queries entered. Users can review previous conversations through its archive feature. Although users can delete responses and conversations, the chatbot might continue to use these responses in its LLM for training. This raises privacy concerns when users enter personal data or proprietary information. OpenAI also discloses that ChatGPT gathers geolocation data, network activity, contact details such as email addresses and phone numbers, and device information.
According to OpenAI’s privacy policy, it collects any personal information a user provides. This includes account information such as name, contact information, payment card information and transaction history. OpenAI also might disclose geolocation data to third parties such as vendors and service providers, and to law enforcement agencies if required to do so by law.
OpenAI said the user retains ownership rights of input data and owns the output, but it “may use Content to provide, maintain, develop, and improve our Services, comply with applicable law, enforce our terms and policies, and keep our Services safe.”
Gemini stores conversations in a user’s Google account for 18 months, but users can change the retention period to three months or 36 months in their activity settings. Gemini conversations can also appear in searches, raising privacy concerns.
Google discloses that it collects conversations, location, feedback and usage information. The Google Privacy Policy claims Google uses collected data to develop, provide, maintain and improve services, and to provide personal services such as content and ads. Customers can delete information from their account using My Google Activity, or by deleting Google products or their Google accounts.
Google said it will share information to third parties with user consent and law enforcement when required.
Which chatbot is better?
There is a bit of a GenAI arms race going on now, with OpenAI and Google making updates to their models. Google has been especially aggressive, perhaps because ChatGPT came out first and Gemini must play catch-up. With each new version of the LLMs, Google and OpenAI make significant gains over their previous versions.
Generally, ChatGPT is considered the best option for text-based tasks while Gemini is the best choice for multimedia content. However, there are other considerations, as noted in earlier sections of this article. Users can try the free versions to determine which works better for them.
There have been several in-depth reviews about the chatbots worth noting:
Researchers from Carnegie Mellon University and BerriAI benchmarked Gemini Pro against GPT-3 and GPT-4 on 10 diverse language tasks with the goal of providing an impartial in-depth analysis. They found Gemini’s strengths included performance on long, complex reasoning chains and translating into non-English languages. On the downside, it struggled with mathematical reasoning — especially with large numbers — showed bias on multiple choice questions and aggressive content filtering blocked many responses. In summary, the researchers concluded Gemini Pro did not match GPT-3 and GPT-4, but “exhibits strengths in handling complexity and reasoning depth.”
Ethan Mollick, an associate professor who studies AI at the Wharton School of the University of Pennsylvania, performed what he called “tasting notes” of Gemini Advanced vs. GPT-4. Mollick concluded that Gemini Advanced is the first advanced AI model that can compete with GPT-4. He said each has its strengths and weaknesses — for example, GPT-4 uses code in a more sophisticated way and is better at hard verbal tasks while Gemini is better at explanations and search. But both “are weird and inconsistent and hallucinate more than you would like.”
Bernard Marr, a futurist and author of Generative AI in Practice, pointed out in a Forbes article that ChatGPT is designed to be more conversational while Gemini processes information and automates tasks more efficiently. Marr’s conclusion after using ChatGPT and Gemini is that ChatGPT-4 is the more powerful chat interface but “Gemini is closing the gap …”.
Neither ChatGPT nor Gemini are perfect, and their developers admit that. Both generate hallucinations and even warn users of that in their responses.
Both of the chatbots include a disclaimer on the bottom of their prompt screens. Gemini’s reads: “Gemini may display inaccurate info, including about people, so double-check its responses.” ChatGPT advises: “ChatGPT can make mistakes. Consider checking important information.”
The Gemini FAQ on Google’s website offers this valuable advice that can apply to all AI tools:
Gemini can’t replace important people in your life, like family, friends, teachers or doctors.
Gemini can’t do your work for you.
Gemini can’t make important life decisions for you.
Generative AI alternatives
GenAI is a fast-moving technology. Besides the updates to ChatGPT and Google Gemini, other companies are working on AI projects. These include AI21 Labs’ Wordtune, Anthropic’s Claude, Glean, Jasper, Open Assistant and Writesonic’s Chatsonic. China’s Baidu search engine uses AI with an application called Ernie Bot. Many productivity applications and SaaS products also incorporate GenAI assistants.
Comparison of ChatGPT vs. Gemini responses
We asked ChatGPT 3.5 and Google Gemini Pro the same requests and prompts to see how their responses would compare. The results are as follows:
Idea generation
Prompt: What are the five hottest IT trends an IT professional should know about?
ChatGPT’s idea generation response to the five hottest IT trends.
Gemini’s idea generation response to the five hottest IT trends.
Thoughts: ChatGPT’s answers were more general while Gemini drilled down into specific areas — for example, generative AI vs. AI/ML and cybersecurity mesh vs. cyber security. ChatGPT’s inability to reference data past January 2022 limits its effectiveness when looking for trending information. Gemini snuck in a few extras under “Bonus trends.”
Creating content
Prompt: Write a two-paragraph summary explaining cyber-resiliency challenges.
ChatGPT’s content generation response to explain cyber-resiliency challenges.
Gemini’s content generation response to explain cyber-resiliency challenges.
Thoughts: Both did a good job of explaining and summarizing a complex issue in two paragraphs, but Gemini included more specifics about the challenges and what can be done about them.
Planning
Prompt: What are the best cloud computing conferences to attend?
ChatGPT’s planning response for the best cloud computing conferences to attend.
Gemini’s planning response for the best cloud computing conferences to attend.
Thoughts: ChatGPT listed more conferences, but its list was a bit dated as several of its conferences have been renamed. Gemini offered greater detail and broke its list into specific areas of expertise.
Developer assistance
Prompt: List 10 frequently used SQL queries for querying a PostgreSQL database.
ChatGPT’s response for developer assistance on frequently used SQL queries for querying a PostgreSQL database.
Gemini’s response for developer assistance on frequently used SQL queries for querying a PostgreSQL database.
Thoughts: The lists were similar, although they used different terms in some cases. A nice feature was the code embedded in the responses. We shortened Gemini’s response to fit on one page, but its longer version included embedded code.
