# RerankAdapter

# Interface: RerankAdapter\<TModel, TProviderOptions\>

Defined in: [packages/ai/src/activities/rerank/adapter.ts:23](https://github.com/TanStack/ai/blob/main/packages/ai/src/activities/rerank/adapter.ts#L23)

Rerank adapter interface with pre-resolved generics.

An adapter is created by a provider function: `provider('model')` → `adapter`
All type resolution happens at the provider call site, not in this interface.

Generic parameters:
- TModel: The specific model name (e.g. 'rerank-v3.5')
- TProviderOptions: Provider-specific options (already resolved)

## Type Parameters

### TModel

`TModel` *extends* `string` = `string`

### TProviderOptions

`TProviderOptions` *extends* `object` = `Record`\<`string`, `unknown`\>
