AI

A tiny GPT you can run, the team that will run AI in a large company, where healthcare's AI money goes, and how AI text gets watermarked. The agents have their own series, Harness.

• Inside a transformer
• The AI Platform team: Organizational AI Governance
• AI in US healthcare: where the money goes
• Watermarks in AI text

Tools I build and publish: rigswig, which reads what a coding agent loads, and agent-neuron, where wrapped agents agree and decide.

• agent-neuron

The loop that builds this site, the graph an agent works in, what a run should leave behind, and what people mean by a harness.

A folder of Markdown notes as the memory of an agent graph: click through an invented firm’s vault, then ask an agent the same question with and without it.

• A vault is a folder
• Read before you act
• Writing back
• Structure an agent can rely on · coming
• The vault inside an agent graph · coming
• Permissions and privacy
• History and review · coming
• At scale · coming

A model that returns typed decisions instead of text: see one request both ways, then move a threshold over scripted decisions and watch what each kind of mistake costs.

• Deciding, not writing
• What a probability is for
• Routing a request to a model
• Gating an agent’s action
• Speed and cost: reading the vendor’s numbers · coming
• Testing it yourself · coming
• The skeptic’s case · coming
• Where a decision model fits in an agent graph · coming

An agent-neuron is a wrapper, and whatever goes inside it (a model, a shell script, a small function or a person) gets the same interface, so any neuron can send to any other.
