# Function: resolveGenerationOptions()

```ts
function resolveGenerationOptions(
  canonical: ChatGenerationOptions,
  nativeFallbacks?: {
    enableThinking?: boolean;
    maxTokens?: number;
    multimodal?: {
      audio?: boolean;
      image?: boolean;
    };
    sampler?: ChatSampler;
    seed?: number;
    temperature?: number;
    topK?: number;
    topP?: number;
  },
): ResolvedGenerationOptions;
```

Defined in: [src/batteries/llm/chat\_common/generation.ts:109](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/generation.ts#L109)

Resolve the canonical [ChatGenerationOptions](../interfaces/ChatGenerationOptions.md) (already merged across option layers) into a
fully-defaulted [ResolvedGenerationOptions](../interfaces/ResolvedGenerationOptions.md). Native per-battery fallbacks are passed via
`nativeFallbacks` and consulted ONLY when the canonical field is absent (canonical wins). The adapter
then maps the resolved shape onto its runtime API.
