XCT-Agentic Platform

Three-Layer AI Platform Stack

From task orchestration to model routing to agent execution — a unified platform built for the solar-powered AI city-state. Each layer is independently deployable, and together they form a complete agentic AI infrastructure.

XCT-Builder

Multi-Engine Orchestration

Don't pick a framework. Let the platform route tasks to the right engine automatically. XCT-Builder implements a dynamic task complexity classifier that selects between graph-based (LangGraph), multi-agent (CrewAI), workflow (n8n), and declarative (Dify) engines — without a single line of config change.

XCT-Agent

Persistent Agent Runtime

Agents that remember. XCT-Agent combines persistent long-term memory with cross-model session management — enabling AI agents that build context over time, across sessions, and across model providers. Every interaction is attributed, auditable, and resumable.

Xcity Argentina Territory

San Juan Province, Argentina

The first Xcity location covers approximately 1 million acres (400,000 hectares) — about 3.5 times the size of Hong Kong. Nestled in a vast valley at the foothills of the Andes Mountains.

Strategic Position

Near the newly built Route 150 International Highway — part of South America's "Two-Ocean Corridor" — and the planned Andes Tunnel, linking Chile's Pacific ports with Argentina's Atlantic seaboard.

Two-Ocean Corridor Andes Tunnel Gold & Copper Reserves Glacial Water Supply

Nestled in a vast valley at the foothills of the Andes Mountains, the land features a mix of plains and valleys nourished by glacial meltwater rivers. Multiple rivers cross the territory, ensuring reliable water resources, while abundant sunshine provides ideal conditions for large-scale solar energy generation. The region is also rich in gold and copper deposits, making it both geographically and resource-wise a rare gem.

Strategically located near the newly built Route 150 International Highway — part of South America's "Two-Ocean Corridor" — and the planned Andes Tunnel, Xcity enjoys a unique position linking Chile's Pacific ports with Argentina's Atlantic seaboard. This corridor forms a natural bridge between the Americas, China, Latin America, Europe, and the Middle East, granting Xcity unmatched advantages as a gateway to global markets.
