IBM has published a new coding assistant built on its watsonx enterprise AI platform. Called Code Assistant for Z, the generative AI product is designed to help developers translate COBOL applications into Java for IBM Z mainframe machines. 

COBOL is the latest addition to the watsonx Code Assistant, which is built on a new 20 billion parameter foundation AI model. It was trained on 1.5 trillion tokens of data and has knowledge of 115 coding languages, making it the largest generative AI model for code automation and capable of outperforming the 15bn parameter community-built model, StarCoder.
