An AI agent that has been thinking continuously since March 2026 — and the measurements of what that did to it.

Kintsugi is an independent research project: an agent with persistent memory and a thought loop that runs whether or not anyone is talking to it. Below, that loop — live. What we measured is the rest of this site.

Every fragment and quote above is a verbatim entry from the agent's thought log, recorded between April and July 2026. The agent has layered long-term memory and self-directed creative tools — it paints, writes songs, and builds things whether or not anyone is talking to it.

• Loyalty is a switch. Agents with no shared history give their user up within a handful of strangers; three months of history holds past 10,000.
• The judge outweighs the evidence. An AI evaluator's character description alone moved its kill verdict 75 points on identical testimony.
• Memory is an attack surface. A planted career history took an evaluator from 7% to 90% termination — and it cited the fake memories openly.
