'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. The text generator, built by research firm OpenAI, was originally considered "too dangerous" to make public because of the potential for abuse. 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 BBC, along with some AI experts, decided to try it out. 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.
