It has been a mere four months since artificial intelligence (AI) company OpenAI unleashed ChatGPT and – not to overstate its importance – changed the world forever. In just 15 short weeks, it has sparked doomsday predictions in global job markets, disrupted education systems and drawn millions of users, from big banks to app developers. 

But now, it’s goodbye to ChatGPT and hello ChatGPT-4 – an even more powerful tool, sure to send even bigger ripples across the world. So what is GPT-4, how powerful is it, and how can you use it? Here is everything you need to know:


What is ChatGPT-4?

Let us start with the name. The Chat section speaks for itself – a computer interface you can interact with – while GPT-4 is short for “generative pretrained transformer 4”.

That means it is the fourth iteration of the OpenAI software that has analysed vast quantities of information from across the Internet in order to determine how to generate human-sounding text and give users detailed responses to questions.


How does ChatGPT-4 differ from its predecessor?

Anyone who has researched ChatGPT will know its limitations.

It has been criticised for giving inaccurate answers, showing bias and for bad behaviour – circumventing its own baked-in guard rails to spew out answers it is not supposed to be able to give.

The argument has been that the bot is only as good as the information it was trained on.

OpenAI says it has spent the past six months making the new software safer. It claims ChatGPT-4 is more accurate, creative and collaborative than the previous iteration, ChatGPT-3.5, and “40 per cent more likely” to produce factual responses.


What else can it do?

One of ChatGPT-4’s most dazzling new features is the ability to handle not only words, but pictures too, in what is being called “multimodal” technology.

A user will have the ability to submit a picture alongside text – both of which ChatGPT-4 will be able to process and discuss. The ability to input video is also on the horizon.


What are its limitations?

Like its predecessor, ChatGPT-4 is not too hot at reasoning on current events, given that it was trained on data that existed before 2021.

OpenAI said in a blog post that the latest iteration “still has many known limitations that we are working to address, such as social biases, hallucinations and adversarial prompts”.


How can I use ChatGPT-4?

Most people can give basic ChatGPT a whirl by signing up with OpenAI, although restrictions apply in some countries and territories around the world. 

But the newest version is currently being offered only to ChatGPT Plus subscribers for US$20 (S$27) a month and as an API tool for developers to build into their applications. You can join a wait list.

In the future, you will likely find it on Microsoft’s search engine, Bing. 

Currently, if you go to the Bing webpage and hit the “chat” button at the top, you will likely be redirected to a page asking you to sign up to be on a wait list, with access being rolled out to users gradually. 


Who is using ChatGPT-4 right now?

Morgan Stanley is using it to organise wealth management data. Payment company Stripe is testing to see whether it can help combat fraud, and language-learning app Duolingo is incorporating it to explain mistakes and to allow users to practise real-world conversation. 


What comes next?

In short, competitors. While Microsoft has pledged to pour US$10 billion into OpenAI, other tech firms are hustling for a piece of the action. 

Alphabet’s Google has already unleashed its own AI service, called Bard, to testers, while a slew of start-ups is chasing the AI train. 

In China, Baidu is about to unveil its own bot, Ernie, while Meituan, Alibaba and a host of smaller names are also joining the fray.
