Local AI experiments, agent systems, and papers worth the time.

Everything here runs on hardware I own. I write up the experiments that worked, the ones that didn’t, and the papers worth reading — with enough detail that you could reproduce them.

What I write about

Local AI

Models running on hardware I own. Quantization, VRAM budgets, what actually fits on a consumer GPU, and the point where local stops being good enough.

Agents

Agent architectures that survive contact with reality: tool design, MCP servers, orchestration, and the failure modes that never make it into the demo.

Papers

Breakdowns of papers worth the time — what the result actually claims, what it quietly does not, and whether it reproduces.
