# oz0 model canary

> Usage and flags for oz0 model canary.

For: Operators and developers looking up a command.

A model canary watches one model ID on one provider record of the tenant: it finds prompts whose first token splits at temperature 0 (border inputs), then checks them once a day with about fifteen one-token calls, billed to the tenant. When the answers differ two days in a row it raises a finding, the model behind the pinned ID changed, and starts the tenant's eval routines whose plugins use the model.

A model that refuses temperature 0 or hides its reasoning cannot be watched, and the canary says so.

## Usage

```bash
oz0 model canary [command]
```
