Engineering intelligence
into the physical world

Elias builds systems that help machines understand, learn from, and act in the real world. His work spans ML infrastructure, large-scale recommendations, NLP, and autonomous robotics — from Google-scale systems to early-stage startups pushing the boundaries of embodied AI.

Currently at Generalist AI, he's part of the team developing general-purpose foundation models for robots — enabling machines to learn from real-world data and adapt to new tasks with remarkable efficiency.

Building robots that
make headlines

Elias is part of the Generalist AI team whose work was recently featured as a Forbes Daily Cover story — profiling how the company is applying AI scaling principles to physical robotics.
