Build updates from Cereal.
Progress from prototype to working humanoid: demos, milestones, and the thinking behind them, straight from the team.
The loss went down. The robot still failed.
A careful failure study published this week shows a world model's training loss can improve while the planner on top of it stays at chance. It is the strongest outside evidence yet for the bar we hold ourselves to: judge a robot by certified outcomes and attested actions, never by its training curves.
Persistence became a benchmark. Here is ours.
The research field has started scoring what a robot believes, not just what it completes. We think that bar is still too low for a machine in a family's home, so here is the three-clause test we hold ourselves to, published as a request for comment.
The Android shipped. The account didn't.
Everyone is building the operating system for robot control, several times over. Nobody is building the account that logs in: whose machine this is, what it remembers, what it may do. The OS for control is crowded. The account for the home is still open.
Agents can write robot skills now. Someone still has to decide if they're real.
A new wave of systems lets LLM agents write robot control code from a prompt. Directionally right, and missing the half that matters in a home: certification. As of today, cereal-os v0.2 lets any frontier agent author skills, and the twin decides if they are real.
The bottleneck was never the body. It isn't the brain, either.
WAIC settled a new consensus: the hardware is ready, the intelligence is not. Both halves still miss the part that makes a robot yours. Capability makes a robot useful. Continuity makes it yours.
What phones teach us about robots
Phones split into hardware and OS, and the OS carries your life between bodies. Robotics has not made that split yet. Cereal is building the layer that does.
Everyday Robots was working. It just never shipped.
Google's Everyday Robots was doing real work inside Alphabet when it was shut down in January 2023, before it ever shipped to the world. Our founders helped build it. Cereal is the regroup to finish the job.
Simulation in the loop: the Everyday Robots patent behind our world loop
US11938638B2 is usually filed under sim-to-real. It is really about keeping a live simulation inside every control cycle of a deployed robot. Here is what it actually says, and how Cereal builds above it.
Jarvis was never the suit
In Tony Stark's compound, the intelligence never lived in any one machine. Armors, arms, and rovers came and went; Jarvis stayed. That is the whole thesis.
Cereal OS v0.1: one mind, two bodies
The first running version of the portable mind: the same intelligence and memory completing the same task on two different robot bodies, in simulation, with every action attested.
The brain already exists: meet Cole
Most teams are still building the mind. Cereal is dropping in one that already works, and giving it a body.
Why we build the mind for life, not labor
Most humanoids are being built for the factory floor. Cereal starts with the home, the people, and the moments where presence matters most.
Introducing Cereal: Jarvis needs a body
AI is leaving the screen. We are giving the assistant that already lives in your life a body.
