Since its release last year, you've probably heard a lot of chatter about chat GPT.

The CEO of the company behind chat GPT says artificial intelligence will reshape society chat GPT.

A language model created by OpenAI has the ability to respond to prompts in a human-like manner.

But this chatbot is just the interface between users and a large language model called GPT 3.5.

And last month, the model's developer, Tech Research Company OpenAI, announced its most advanced model yet.

The GPT 4 is really good at solving problems and writing original texting code.

So good that it's got some AI researchers asking everyone to press pause.

Now, an open letter signed by Elon Musk, Steve Wozniak, and a number of top AI scientists, is calling for a six-month pause on AI development.

They're arguing, quote, powerful AI systems should be developed only once we are confident that their effects will be positive and the risks will be manageable.

So what is the real difference between GPT 4 and its predecessor?

And why does it scare AI experts so much?

I'm Sophie Bushwick, and I'm Kelsal Harper, and you're listening to Tech Quickly.

So what exactly is this artificial intelligence?

GPT stands for generative, pre-trained transformer, which is a type of large language model, and that is a type of AI program that can analyze and generate text.

Basically, researchers build a machine learning program called a neural network, because its structure is inspired by the human brain, and then they feed it a bunch of text, so it can learn the patterns of which words generally follow, which other words.

And then eventually, it learns to generate its own sentences, and then humans test it out and tweak its responses to be more coherent.

Yeah, I've played around a little bit with chat GPT, and it can hold a conversation and write pretty darn well.

I mean, we even published a statement from chat GPT about why it should be regulated, right?

Yeah, yeah.

But you're saying GPT 4 is even better?

GPT 4 blows GPT 3.5 out of the water in some areas, but it also has some of the same problems.

So let's start with the good stuff. GPT 4 can do something different, which is analyze images as well as text.
