A sensational story about the Israeli prime minister's "psychiatrist" has exploded online, but it was AI-generated, originating on one of hundreds of websites researchers warn are churning out tech-enabled fiction masquerading as news. Propaganda-spewing websites have typically relied on armies of writers, but generative artificial intelligence tools now offer a significantly cheaper and faster way to fabricate content that is often hard to decipher from authentic information. Hundreds of AI-powered sites mimicking news outlets have cropped up in recent months, fueling an explosion of false narratives -- about everything from war to politicians -- that researchers say is stoking alarm in a year of high-stake elections around the world.

If you ask many people to name the technology categories that are creating sweeping change right now, cloud computing and Big Data analytics would probably be top of mind for a lot of them. However, there is an absolute renaissance goind on right now in the field of artifical intelligence and the closely related field of machine learning. Some of the biggest tech companies are helping to drive the trend, and Google added to the momentum on this front this week. Specifically, Sundar Pichai, Google's CEO, said on a conference call, "I do think in the long run we will evolve in computing from a mobile-first to an A.I.-first world." In this post, you'll find a collection of the most notable A.I. tools that have recently been open sourced.
