With the recent release of AI-based Chatbots like ChatGPT, the search bar has become an obsolete artifact of bygone times. It is now possible to have a conversation with a chatbot and to receive a concise summary of several relevant source documents for further detail.

While ChatGPT is a useful tool for general questions and answers, it falls short when it comes to providing specialized knowledge, such as in the field of Automated Test Equipment (ATE) testing. ChatGPT has been observed to provide inaccurate information or to fill knowledge gaps with fabricated answers (sometimes called “hallucinations”), which makes it an unreliable source of information. Teradyne is currently developing a chatbot interface to MyInfo. To ameliorate these issues, Teradyne is employing specialized techniques including indexing, vector search methods, prompt engineering, and model fine tuning to ensure reliable results.

There is a critical secondary requirement when we use chatbots for work – security. We must ensure that our company IP, as well as our customer’s IP, is not inadvertently released out into the wild. The chatbot landscape has finally matured to the point that Teradyne’s strict security requirements can be met, not only as described above, but additionally by isolating each customer’s IP from other customers and even with restricting Teradyne Applications and Field Service support to only those authorized for that specific customer account.

Teradyne’s chatbot interface to MyInfo will support Test Engineers in their search for specialized knowledge of Teradyne’s tester.
