Jev: AI That Gives the Same Answer Every Time

Why can AI give you a different answer every time you ask the same question?

Chat AI like ChatGPT predicts its answer one word at a time, so each try can come out a little different. That's fine when it writes an email for you, but software needs the same answer to the same question, every time. A new kind of AI called Jev is built for exactly that.

What does that look like at work?

Say a customer email comes in, and you need to know three things: what the issue is about, how urgent it is, and whether it's a complaint. If you ask chat AI twice, you can get different answers each time. Your software can't act on answers that keep changing.

How is Jev different?

Jev, from a startup called TypeSafe AI, picks from the options you give it and answers all three questions in one go. It's built to give the same answers every time, along with how sure it is. Because it doesn't write anything, it answers in under a second by TypeSafe's own numbers, and costs far less than chat AI.

Where does chat AI fit in then?

Jev and chat AI work best together. Your software sends the email to Jev to sort it, and chat AI writes the reply. You get a product that behaves the same way every time and still sounds human.

How have the big AI companies responded?

TypeSafe launched Jev on September 15. Just two weeks later, OpenAI announced its own version, called the Decisions API, and soon opened it to all developers.

What to remember

Chat AI is great at writing, and Jev gives software the same answer every time, fast and cheap. Use the two together, and you can build AI products that are far more useful and that people can trust.
