ChatGPT is trialling a subscription service in the US
The company behind the popular AI chat bot is testing a subscription service in the US.
For $20 (£16) a month, subscribers get access to the platform, even at peak times when it's difficult to log in, and also "priority access" to new features, according to chat bot creator OpenAI.
The company plans to make the trial more broad-based, but for now it will only be offered to those on a waiting list.
The free version will still be available, the company said.
In a blog post, OpenAI said it hopes the subscription will support free access. Currently, it costs the company a small amount each time the chat bot is used.
ChatGPT convincingly gives human answers to questions using information from the Internet, but it's not live connected - it uses data from the Internet as it was in 2021.
The new chatbot is all the rage
Nick Cave says AI Nick Cave texts 'suck'
A few days after its launch, OpenAI CEO Sam Altman tweeted that the chatbot had already been used more than a million times, though the company has not released any more data since.
The chat bot has captured people's imaginations, as it is able to mimic a variety of writing styles, from journalists and doctors to rock stars and essay writers.
Musician Nick Cave called the chatbot's attempts to write songs in his style a
"grotesque mockery."
ChatGPT is used not only for fun, but also to write website and marketing copy, find cooking recipes, and write or review programme code.
There are fears that students are already using the programme for homework, and some cybersecurity experts have warned that it could be manipulated to write malicious software, known as malware.
the future of search engines
On Tuesday, OpenAI unveiled a tool that it says can tell whether a text was written by a human or an artificial intelligence.
Some experts believe that decent chatbots are the future of search engines - where AI scours the Internet for a correct answer to a search query, rather than providing pages of links.
But ChatGPT does not currently provide information or comment on its accuracy, and there are many examples of it presenting misinformation as fact.
It is also limited to the content of the Internet in 2021. The version released now is the third, and the company has stated that the next generation is currently under development.
ChatGPT is known as a language learning model, and many other companies are developing it.
Google's model is called Lamda, and it was so compelling that Blake Lemoine, one of the engineers who worked on it, was convinced it was sentient.
Mr. Lemoine was fired, and Google has always denied that claim. The company has not released Lamda to the public.
