The heroes behind deployment are often underrated. A strong, general model is not enough to get robots into production. Anyone who has really deployed knows that most of the important lessons only show up in the field — and you need serious infrastructure to capture them. At Dyna, we’ve spent a lot of time building observability, auto-labeling, feedback, and evaluation systems that turn deployment into a continuous learning loop, with humans guiding the loop where they add the most value. That loop is critical. It tells us where models actually fail, what needs to be solved fundamentally, and where our foundational research should go next — instead of patching problems one deployment at a time. Deployment isn’t just a business use case for us. It’s what powers the data and feedback flywheel behind scalable robotics. More here: There’s probably a lot more behind it than you’d expect.

An hour of lab evals catches a model that doesn't work. It won't catch one that fails once every two hundred trials, or degrades over a week, or runs fine on this robot and badly on the one beside it. So the eval moved to where the work is. Every episode, every site, graded on the customer's definition of good. Over a terabyte a day, autolabelled into SOP steps, outcomes, and failure modes. Today, a new Dyna deployment goes from setup to production ROI in as little as three days. This is just scratching the surface. Also - we're hiring across deployment research:
