Google revealed that Lens, its AI-based camera tool, can now identify over a billion items. That's a significant increase versus a year ago, when the search giant launched an early version with the capability to detect around 250,000 items. Lens was trained with Google's DeepMind system, full details at the Google Blog.
According to The Verge, the one billion figure comes from products that are listed via Google Shopping:
The 1 billion items figure comes from products available through Google Shopping, so it likely doesn’t include more obscure, unshoppable objects, such as a gaming console from the 1990s or the first edition of a rare book. But it covers a huge range of things that could appease someone who’s simply just looking up an item they’re curious about.
