# Model-keyed fallback policies

## Fallback policy follows the requested model

You can now define a separate ordered fallback chain for each requested model. Fabro selects the chain once from the original request and does not jump into another model's policy while failing over.

```toml title="run.toml" theme={"languages":{"custom":["/languages/dot.json","/languages/fabro.json"]}}
[run.model.fallbacks]
"kimi-k3" = ["moonshot:kimi-k3", "openrouter:kimi-k3", "claude-opus"]
```
