Nvidia releases software tools to help chatbots watch their language

Nvidia Corp., a major supplier of chips and computing systems for artificial intelligence, on Tuesday, released a set of software tools aimed at helping chatbots watch their language. Nvidia's chips have helped companies like Microsoft Corp. add human-like chat features to search engines like Bing. Nvidia's software tools, provided free of charge, are designed to help companies guard against unwanted responses from chatbots. But the Nvidia tools are also designed to help AI system creators put into place important safety measures, such as ensuring that chatbots do not respond with potentially dangerous information such as how to create weapons or send users to unknown links that could contain computer viruses.
