Swiss retailer uses open source Ray tool to scale AI models

After more than 20 years in the retail business, Switzerland-based online marketplace Ricardo wanted to fix some of the problems its users had buying and selling items. Ultimately, Ricardo settled on a system based on the Ray open source Python framework developed by AI vendor Anyscale. Like most such marketplaces, Ricardo previously used a category business model in which the items sellers listed for sale were placed under different categories. However, sometimes end users clicked on the wrong categories and were unable to find the items they wanted. Also, since Switzerland has four official languages, sometimes customers were describing the product they wanted in a language that was different from what the website was picking up.
