If that's a typo and they meant to say "AI", then I may be remembering the article(s) being alluded to:

> AlphaTensor discovered algorithms that outperform the state-of-the-art complexity for many matrix sizes. Particularly relevant is the case of 4 × 4 matrices in a finite field, where AlphaTensor’s algorithm improves on Strassen’s two-level algorithm for the first time, to our knowledge, since its discovery 50 years ago.

If I had to guess, I'd say it's a Frenchism ("Intelligence artificielle").
