The former Nabisco plant in Larimer once served as a leader in baking technology. Now it's fast becoming a home for a 21st century form of high tech -- artificial intelligence.

That may not be a stretch after Walnut Capital recently signed leases with three companies involved in AI to take space at the old plant now known as Bakery Square.

The signings come after the Shadyside-based developer converted 20,000 square feet in Bakery Square Three into move-in ready space for AI firms and as it focuses on making Pittsburgh a leader in starting and growing AI-based firms.
