Brain
The LLM powering a Mind's reasoning — swappable without replacing the Soul.
The Brain is the LLM layer that powers a Mind's thoughts and reasoning. Tasks are auto-routed to the most appropriate model — reasoning, coding, fast response, and so on — with no single-vendor lock-in.
The Brain is separate from the Soul . If the underlying model is swapped or upgraded, the Mind's identity, Memory , Tenets , and history remain intact. The Soul persists; only the Brain changes.
