Amazon has unveiled "Nova," a suite of powerful AI tools for creating text, images, and videos, at its AWS conference in Las Vegas. The highlight is Nova Reel, which generates six-second videos from a single image or text, with plans to extend to two-minute videos. Another innovation, Canvas, turns text into images. Amazon also revealed plans for a multi-modal model to process text, images, speech, and videos. CEO Andy Jassy emphasized the focus on low cost and high speed, aiming to challenge rivals like Adobe, Meta, and OpenAI.
