Kyberos — an agent that acts
[ Product · Built on our research ]
Context
Most assistants answer; we wanted an agent that acts. One interface that can research a topic, browse the web on your behalf, plan a real-world outing, and hand back structured results.
Constraint
Long-horizon tasks fall apart without structured planning — and users only trust an agent they can watch. The system had to stream its plan, steps, and reasoning live, not just its final answer.
System we built
A production agent platform built directly on our published GATS research: a three-layer planner (symbolic domains → learned statistics → frontier LLM) drives a tiered tool registry — web search and reading, structured report synthesis, an autonomous browser agent that streams live frames into the UI, voice conversation, and MCP integrations — over a server-sent-events pipeline, with a React front end that renders the agent's working "mind" in real time.
Outcome
The planning framework from the paper doing the planning in a live product: deterministic tool routing, auditable step timelines, and research-grade capabilities in front of real users.
