AGY 2.6 Autonomous Core Engine

The central agentic brain managing prompt intent parsing, long-term transcript memory, and Gemini 4 multi-agent orchestration.

Underlying Mechanics

  • ▸Native Gemini 4 Argon & Carbon model execution pipelines
  • ▸Zero-loss session persistence with automatic transcript journaling
  • ▸Dual-lane tool routing (Eager native vs Lazy MCP sidecars)
