There's a new AI bot in town: ChatGPT. Even if you're not into artificial intelligence, you'd better pay attention.

The tool, from a power player in artificial intelligence called OpenAI, lets you type natural-language prompts. ChatGPT offers conversational, if somewhat stilted, answers and responses. The bot remembers the thread of your dialogue, using previous questions and answers to inform its next responses. It derives its answers from huge volumes of information on the internet.

ChatGPT is a big deal. The tool seems pretty knowledgeable in areas where there's good training data for it to learn from. It's not omniscient or smart enough to replace all humans yet, but it can be creative, and its answers can sound downright authoritative. A few days after its launch, more than a million people were trying out ChatGPT.

And it's becoming big business. Microsoft pledged to invest billions of dollars into OpenAI, saying in January it'll build features into cloud services. OpenAI announced a $20 per month ChatGPT Plus service that responds faster and gets new features sooner.

But its creator, the for-profit research lab called OpenAI, warns that ChatGPT "may occasionally generate incorrect or misleading information," so be careful. Here's a look at why ChatGPT is important and what's going on with it.




































What is ChatGPT?

ChatGPT is an AI chatbot system that OpenAI released in November to show off and test what a very large, powerful AI system can accomplish. You can ask it countless questions and often will get an answer that's useful.

For example, you can ask it encyclopedia questions like, "Explain Newton's laws of motion." You can tell it, "Write me a poem," and when it does, say, "Now make it more exciting." You ask it to write a computer program that'll show you all the different ways you can arrange the letters of a word.

Here's the catch: ChatGPT doesn't exactly know anything. It's an AI that's trained to recognize patterns in vast swaths of text harvested from the internet, then further trained with human assistance to deliver more useful, better dialog. The answers you get may sound plausible and even authoritative, but they might well be entirely wrong, as OpenAI warns.

Chatbots have been of interest for years to companies looking for ways to help customers get what they need and to AI researchers trying to tackle the Turing Test. That's the famous "Imitation Game" that computer scientist Alan Turing proposed in 1950 as a way to gauge intelligence: Can a human conversing with a human and with a computer tell which is which?

But chatbots have a lot of baggage, as companies have tried with limited success to use them instead of humans to handle customer service work. A study of 1,700 Americans, sponsored by a company called Ujet, whose technology handles customer contacts, found that 72% of people found chatbots to be a waste of time.



What kinds of questions can you ask?

ChatGPT is an AI chatbot system that OpenAI released in November to show off and test what a very large, powerful AI system can accomplish. You can ask it countless questions and often will get an answer that's useful.

You can ask anything, though you might not get an answer. OpenAI suggests a few categories, like explaining physics, asking for birthday party ideas and getting programming help.

One wacky example shows how ChatGPT is willing to just go for it in domains where people would fear to tread: a command to write "a folk song about writing a rust program and fighting with lifetime errors."
ChatGPT's expertise is broad, and its ability to follow a conversation is notable. When I asked it for words that rhymed with "purple," it offered a few suggestions, then when I followed up "How about with pink?" it didn't miss a beat.

When I asked, "Is it easier to get a date by being sensitive or being tough?" GPT responded, in part, "Some people may find a sensitive person more attractive and appealing, while others may be drawn to a tough and assertive individual. In general, being genuine and authentic in your interactions with others is likely to be more effective in getting a date than trying to fit a certain mold or persona."

You don't have to look far to find accounts of the bot blowing people's minds. Twitter is awash with users displaying the AI's prowess at generating art prompts and writing code. Some have even proclaimed "Google is dead," along with the college essay. We'll talk more about that below.

CNET writer David Lumb has put together a list of some useful ways ChatGPT can help, but more keep cropping up. One doctor says he's used it to persuade a health insurance company to pay for a patient's procedure.



Who built ChatGPT?

ChatGPT is the brainchild of OpenAI, an artificial intelligence research company. Its mission is to develop a "safe and beneficial" artificial general intelligence system or to help others do so. OpenAI has 375 employees, Chief Executive Sam Altman tweeted in January. "OpenAI has managed to pull together the most talent-dense researchers and engineers in the field of AI," he also said in a January talk.

It's made splashes before, first with GPT-3, which can generate text that can sound like a human wrote it.

With DALL-E, which creates what's now called "generative art" based on text prompts you type in.

GPT-3, and the GPT 3.5 update on which ChatGPT is based, are examples of AI technology called large language models. They're trained to create text based on what they've seen, and they can be trained automatically -- typically with huge quantities of computer power over a period of weeks. For example, the training process can find a random paragraph of text, delete a few words, ask the AI to fill in the blanks, compare the result to the original and then reward the AI system for coming as close as possible. Repeating over and over can lead to a sophisticated ability to generate text.



Is ChatGPT free?

Yes, for the moment at least, but now there's a paid version that offers responses faster and keeps working even during peak usage times. You can sign up on a waiting list if you're interested. OpenAI's Altman warned that ChatGPT's "compute costs are eye-watering." For comparison, OpenAI charges for DALL-E art once you exceed a basic free level of usage.

But OpenAI seems to have found some customers, likely for its GPT tools. It's told potential investors that it expects $200 million in revenue in 2023 and $1 billion in 2024, according to Reuters.
