'Dangerous' AI offers to write fake news

An artificial intelligence system that generates realistic stories, poems and articles has been updated, with some claiming it is now almost as good as a human writer.

But now a new, more powerful version of the system - that could be used to create fake news or abusive spam on social media - has been released.

The model, called GPT-2, was trained on a dataset of eight million web pages, and is able to adapt to the style and content of the initial text given to it.

As a result, the released version had far fewer parameters - phrases and sentences - than used during training.

Article author Tristan Greene added: I'm terrified of GPT-2 because it represents the kind of technology that evil humans are going to use to manipulate the population - and in my opinion that makes it more dangerous than any gun.'

We began with the first sentence of the real story: Chinese search engine Sogou is creating artificial intelligence lookalikes to read popular novels in authors' voices.

As such, these users are tricked into thinking they are reading from a real author - the book is made to sound authentic as soon as they try and read.

'From my brief experiments with the model, it's pretty clear that a large portion of the data has been trained by internet news stories,' he said.

'But once the initial (and understandable) concern dies down, what is left is a fundamentally crucial debate for our society, which is about how we need to think about a world where the line between human-generated content and computer-generated content becomes increasingly hard to differentiate,' he added.
