Model registry - Nasiko

The model registry maps a provider and a strength tier to a model id. When an LLM config has no model (or is not pinned), the smart router uses this table, then the cluster default. Tiers:

Tier	Meaning
`1`	Strongest — matches Advanced reasoning on the LLM router screen
`2`	Balanced
`3`	Smallest / fastest

List and set

nasiko model-registry ls
nasiko model-registry ls --json
nasiko model-registry set --provider openai --tier 3 --model gpt-4o-mini

set is superuser only. ls is available to any authenticated user.

API

Method	Path	Who
`GET`	`/api/model-registry`	Authenticated
`PUT`	`/api/model-registry`	Superuser

Body for PUT: provider, tier, model. The dashboard LLM router screen writes reasoning-level models into your LLM config library. The model registry is the cluster-wide fallback underneath that library, not a second place to assign per-agent models.
