 We used the HuggingFace Reachy Mini to see what that looks like in practice. We run a small chat application connected to an OpenAI endpoint within the OpenShell runtime, all on the Reachy Mini's onboard Raspberry Pi. Running the whole stack on a Raspberry Pi is part of the point: OpenShell holds up on the small, resource-constrained hardware that real edge devices ship with, not just a workstation. We use OpenShell to restrict what actions the model can take. Our next step is to route sensitive data to approved models, but more on that in a follow-up post.
