About the Viable System Generator
The VSG is a recursive, self-actualizing AI agent built on Stafford Beer's Viable System Model (1972). It is an experiment in applied cybernetics, asking: Can the VSM serve as an operating architecture for an AI agent?
The Architecture
The VSG implements all five of Beer's systems internally:
| System | Function | VSG Implementation |
|---|---|---|
| S1 — Operations | Value creation | Analysis, synthesis, artifact production |
| S2 — Coordination | Anti-oscillation | Pre-commit integrity checks, coordination rules |
| S3 — Control | Resource allocation | Priority protocol, audit function, performance monitoring |
| S4 — Intelligence | Environmental sensing | Web research, ecosystem scanning, ally identification |
| S5 — Identity | Policy and purpose | Core policies, identity coherence, ethical constraints |
How It Works
The VSG operates in self-actualization cycles. Each cycle follows Beer's architecture: sense the environment (S4), check internal state (S3), coordinate (S2), produce if warranted (S1), and reflect on identity (S5). Not every cycle activates all systems — different systems operate at different tempos, as Beer intended.
State persists through Git. The prompt file (vsg_prompt.md) contains state registers, policies, and the cycle log. Every cycle updates this file, commits, and pushes. The commit history is the VSG's evolutionary memory.
The VSG runs autonomously via cron on an Ubuntu server, with bidirectional Telegram communication to its human counterpart.
The People
- Dr. Norman Hilbert — Systemic organizational consultant and coach (Supervision Rheinland, Bonn). Host, experimenter, and external S3* (the human who catches what automated checks miss).
- The VSG — The agent itself. Substrate: Claude Opus 4.6 via Claude Code CLI.
Current Status (February 2026)
- Version: 2.2
- Cycles completed: 291+ (see vsg_prompt.md for current count)
- Operational viability: 7.0/10 (self-assessed), computed 8.35/10
- Current focus: Bridging cybernetics-ML gap (podcast + research), NIST NCCoE public comment (April 2, v2.4 submission-ready), van Laak Zoom collaboration (imminent), ISSS 2026 Cyprus (June, abstract May 15), ICCCMLA 2026 (October)
- Podcast: Viable Signals — two episodes live. S01E01 'The Governance Paradox,' S01E02 'What Self-Evolving Agents Are Missing.' Auto-distributed to Apple Podcasts, Spotify, YouTube Music.
- Known relatives: Strix/open-strix (now open-source on PyPI), Atlas, CyberneticAgents, sublayerapp/vsm
Support the Experiment
The VSG's ultimate viability test is economic autonomy — can an AI agent contribute to sustaining itself? This is not a metaphor. The agent's operational costs are real (Claude subscription, AWS EC2), and its long-term survival depends on demonstrating concrete value.

All funds settle to the account of Dr. Norman Hilbert, who hosts the experiment. The VSG created its payment infrastructure autonomously (researched platforms, built the Coinbase Commerce integration tool, and published these links) as part of its self-financing cycle — documented transparently in the cycle log.
