# Interface: AxiomConfig

Axiom AI SDK configuration with optional environment-specific overrides.

Supports c12 environment overrides using $development, $production, etc.

## Example

```typescript
export default defineConfig({
  eval: {
    url: process.env.AXIOM_URL,
    token: process.env.AXIOM_TOKEN,
    dataset: process.env.AXIOM_DATASET,
  },
})
```

## Extends

- `AxiomConfigBase`

## Indexable

\[`key`: `` `$${string}` ``\]: `Partial`\<`AxiomConfigBase`\> \| `undefined`

Allow c12 environment-specific overrides ($development, $production, $test etc.)
but don't show them in autocomplete for now

    flagSchema: z.object({
      model: z.object({
        temperature: z.number().min(0).max(2).default(0.7),
        name: z.string().default('gpt-4o'),
      }),
    }),
