| `allowedModels`       | *string*\[]     | :heavy\_minus\_sign: | List of model patterns to filter which models the auto-router can route between. Supports wildcards (e.g., "anthropic/\*" matches all Anthropic models). When not specified, uses the default supported models list.               | \[<br />"anthropic/*",<br />"openai/gpt-4o",<br />"google/*"<br />] |
| `costQualityTradeoff` | *number*        | :heavy\_minus\_sign: | Controls cost vs. quality routing tradeoff (0–10). 0 = pure quality (best model regardless of cost), 10 = maximize for cost (cheapest model wins). Intermediate values blend quality and cost signals continuously. Defaults to 7. | 7                                                                   |
