Prototype fast without creating a rewrite for later. New copper-rs skills help coding agents like Claude and Codex build robots on a deterministic, production-grade foundation from day one, while preserving the fast iteration needed during early development.

Copper now goes end to end. We added an open-source ViTFly-based autonomy example that flies through complex environments at high speed, while also deploying an NVIDIA TensorRT-based self-driving stack with a customer. From Candle 🤗 to CUDA, Copper brings learned models into the same deterministic, observable, and replayable robotics runtime as the rest of the system.
