Canonical definitionRelational AI
Companion Core is the runtime that maintains a Companion's identity and coordinates memory, foundation models and Souls.
It is the part of the Almaia stack responsible for keeping a Companion consistent across time, devices and modalities.
What it is not
- —Not a prompt template.
- —Not tied to a single foundation model provider.
In practice
Switching the underlying model should not change who Lena is. Companion Core is what makes that true.
Frequently asked
- What breaks without a Companion Core?
- Identity drift: the same product feels like a different entity across sessions, devices or model upgrades.
