Microsoft unveils a better-behaved chatbot after its last one became a NAZI

The last time Microsoft released a "bot" onto the internet, it quickly became a Donald Trump-supporting, Nazi-sympathising, conspiracy theory-believing racist . It has unveiled a website called CaptionBo t, which uses clever algorithms to recognise images. Users are asked to give a star rating to reflect its accuracy, letting the bot learn from its mistakes and improve its skills. "I can understand the content of any image and I'll try to describe it as well as any human," the bot said. If you look at the tweets above, you'll see what happened to Tay, Microsoft's last creation. It was supposed to be a "chill" machine, but ended up getting tricked into spouting racist rhetoric, praising Hitler and calling for Mexico to build a wall to keep migrants out of the US.
