01

Ambient runtime

  • Always-on mic listener plus browser, Siri, and API inputs
  • Fast paths for timers, media control, and lightweight commands
  • Distributed services keep audio, routing, and tool execution decoupled
02

Supervisor architecture

  • Specialized subagents route music, calendar, home, and general tasks
  • Tool-heavy requests stay inspectable instead of disappearing into a monolith
  • Designed around low latency, graceful fallbacks, and clean handoffs
03

Memory and feedback

  • Titan embeddings plus pgvector memory for preference recall
  • SQL filters combine with vector retrieval for better personalization
  • Langfuse traces tool correctness, latency, and generation quality
