Open source

Everything above
the kernel is open.

One C++ core — inference, model management, routing — with SDKs for Swift, Kotlin, React Native, Flutter, TypeScript, and C++. LLM, speech, vision, and voice on device by default, cloud by policy, in a few lines of code.

The stack

One C++ core. Every target falls out of it.

The SDKs are thin bindings over the same open-source runtime, so every platform gets the same models, the same API, and the same speed — and a new target is a new binding, not a rewrite.

The hybrid layer

On-device by default. Cloud by policy.

Every request starts local. When a task needs more than the device can give — a bigger model, a longer context — the Control Plane's routing policies send it to cloud and bring it back, without your app code changing. Latency, privacy, and cost decide; you set the policy.

AI

LLM

Quantum computing uses quantum mechanics to process information in fundamentally different ways than classical computers, enabling exponentially faster calculations for specific problems.

RunAnywhere Labs

A research-first inference lab. We hand-write the kernels that make consumer silicon fast — and open-source the SDKs and infrastructure that run them on every platform.
