Models
An agent is a model plus a harness — the scaffolding of tools, permissions, context management and workflow around it. The frontier models inside these tools have largely converged, so the harness now does much of the differentiating work. This page indexes the coding agents worth knowing, plus the security-focused agent systems built on the same pattern. Agents tagged bring your own model can run against local or self-hosted models from the registry — the privacy-preserving combination.
