About

I’m building Sigma Runtime, a persistent runtime for long-horizon AI systems. My work focuses on continuity, runtime state, and how AI systems behave over extended interactions rather than isolated prompts. Currently exploring runtime infrastructure for persistent agents, AI companions, operational workflows, and long-running human-AI collaboration.

Sigma Runtime - Persistent runtime for long-running AI systems

Sigma Runtime is a persistent runtime for long-running AI systems. Instead of treating every interaction as a new session, Sigma Runtime preserves continuity across conversations, workflows, and operational tasks. It’s designed for AI that operates over days, weeks, or months, enabling persistent state, adaptive identity, and seamless context continuity. Open Beta is now available.
