Introducing TRACE: deployment-time compute scaling for robot learning. From a few Tutor demos, frontier LLM agents rebuild a robot's task in sim and train reliable, human-speed policies. Performance becomes a function of compute. TI-0.1 is our first model trained with TRACE.

We raised a $75M Series B to deploy intelligent robots now, led by a16z, with participation from USV and Neo. Tutor robots work real jobs across the United States, directed by human “tutors” and the foundation models we’ve trained on the work done. This round accelerates frontier model training, robot manufacturing, and deployment into industry. We’re in almost 4x as many sites as a year ago; nearly a third of this year’s deployments went to existing customers coming back for more; and we’re on track to have more than 1,000 robots under contract by the end of 2027. Our mission is to proliferate robotics for the common good. If you want to make robots reliably do things others think are impossible, for people who’ve never had access to this technology, join us.

I'm excited to share Tutor's next generation of robots, pushing the frontier of robot capabilities in real customer deployment. Meet Sonny, a human-inspired mobile robot running our Ti-series VLA built for the real world.

Excited to share Tutor's Data Factory 1, a 100 robot semi-humanoid research farm and the largest robot data factory in the United States. Our first embodiment “Cassie” is deployed at industrial scale across the supply chain. We built DF1 to bootstrap fleet-scale learning for our "Sonny" industrial semi-humanoid embodiment, powered by our first end-to-end robot foundation model Ti0.
