Twitter announced it is acquiring London-based artificial intelligence startup Magic Pony Technology to help provide a professional polish to tweeted live videos. The social giant reportedly paid about $150 million to purchase Magic Pony. Twitter CEO Jack Dorsey said he was buying the company “so Twitter can continue to be the best place to see what’s happening and why it matters, first.” Twitter has been emphasizing video in recent months, and machine learning is “increasingly at the core of everything we build,” said Dorsey. In addition to using machine learning, “Magic Pony’s technology uses artificial intelligence for visual effects,” notes Bloomberg. “It can be used to clean up pixelated images or create new images” and “to improve video streaming.”
