PI-1 Open Source Pressures Skild

Physical Intelligence is trying to make the robot brain cheap and widespread, which would push Skild to win on deployment and tooling instead of the base model alone. PI has already moved in that direction by open sourcing its earlier π0 model and weights after raising $400 million, while Skild sells a cloud based intelligence layer that turns robot specs into runnable control interfaces and improves from field data across customers.

• PI and Skild are direct horizontal competitors. Both aim to sit above robot hardware and below end applications, so an open base model from PI would shift value toward adapters, safety layers, workflow software, and customer specific tuning.

• PI has funding to subsidize ecosystem building. Its total estimated funding reached about $1.07 billion by November 2025, versus Skild at about $1.7 billion after its March 2026 round, which means both can spend heavily on data, compute, and developer adoption before strong software margins appear.

• Open source pressure is not hypothetical. NVIDIA also released Groot N1 in open source in March 2025, which suggests the foundation layer in robotics may start to resemble open infrastructure, while commercial winners capture revenue from integration, reliability, and vertical performance.

The likely path is a split market. Open models will set the floor for general capability, and companies like Skild will move up the stack into managed training, private cloud inference, and vertical modules for security, warehouses, and inspection. In robotics, the durable moat is becoming live deployment data and production workflows, not just model weights.
