Robotics had a big summer, and it is genuinely hard to tell who is doing what. Claire Zau met with Lightspeed partner Amber Yang in front of a whiteboard to draw the whole market on two axes. How general is the model, and how general is the body.Yang explains what actually changed at the model layer, why robots cannot just be trained on the internet the way language models were, and why she thinks humanoids are not about to get cheap. Roughly 40 to 60 percent of a humanoid build is actuators, and

NVIDIA just open sourced the piece it says was missing from the agent stack.

Claire explains why TypeSafe calls it a System One model, how it differs from the classifiers developers have used for years, and where she believes the real gain is:

Santi ran a previous company to about a hundred million, then lost nine months to a legacy ERP migration that left him staring at a blank screen while lenders and investors waited on numbers. His argument is that the ERP looks too big to attack directly, so startups go after an adjacent wedge instead, get good at it, and end up dependent on the system they meant to replace.

Gyde calls itself the first AI-native insurance, wealth and health brokerage.
