Wolfram Research released Mathematica 15 on June 16, 2026, with an AI Assistant already built in and ready to use, according to Stephen Wolfram's announcement. It also includes improvements to its tools for data analysis and mathematics.

The AI works right away. When you open Mathematica after updating to version 15, the assistant is already there—you don't need to sign up, enter passwords, or buy anything extra. For researchers and engineers who depend on Mathematica for calculations, this makes the AI much easier to use from day one.

The assistant can do several things: it can write code for you based on what you describe in English, it can run that code, it can find and fix problems when code breaks, and it can convert code from other programming languages like Python into Mathematica's language. That last part is useful. Converting between different programming languages is normally done by hand and requires real expertise. The AI doing some of that work saves time for people who use multiple tools.

Most coding tools now have some kind of AI helper. What makes Mathematica's version different is that it's connected to Mathematica's own calculation engine. When the AI writes code, it can actually run it and see if it works. This is like having the AI check its own work in real time, rather than just making a suggestion and hoping someone else runs it correctly elsewhere.

Other companies are also putting AI helpers directly into their specialized software instead of just offering them as separate add-ons. Mathematica has always been known for having a huge library of built-in operations—tens of thousands of them—that cover everything from physics and geography to money and time-based data. An AI that understands this library could help researchers find answers faster.

Version 15 also adds new features for data analysis and mathematics, though the full list wasn't available. Based on past releases, Mathematica usually adds hundreds of new operations with each major update.

The real question for people who already use Mathematica is whether the AI will handle some of the language's trickier features. Mathematica has some unusual ways of doing things that differ from other programming languages. The AI will need to learn these differences quickly or it will make mistakes.

Because the AI is already turned on for everyone who updates, all users get it automatically—students, researchers at universities, and professional users. You don't have to do anything except update the software.

Mathematica 15 is available now.
