## Statements (checkable)
0. Gemini model versions are stable, preview, latest or experimental. A latest alias points to the latest release of a model variation (stable, preview or experimental) and is hot-swapped with every new release; for breaking changes a 2-week email notice is given before the version behind latest changes.  [✓0 ✗0]
1. Stable model strings usually do not change and are recommended for most production apps; preview models are deprecated with at least 2 weeks notice.  [✓0 ✗0]

## Fix
```text
Pin a stable model string (e.g. gemini-3.6-flash) in production, and re-run evals when a -latest alias moves.
```
