providerOptions on embed, embedMany

[volkyeth]

Feature Description

TL;DR: add a providerOptions parameter on embed and embedMany to support provider-specific settings

functions like generateText() and generateImage() accept a providerOptions for provider-specific settings.

e.g.:

import { google } from '@ai-sdk/google';
import { GoogleGenerativeAIProviderOptions } from '@ai-sdk/google';
import { generateText } from 'ai';

const { text } = await generateText({
  model: google('gemini-1.5-pro-latest'),
  providerOptions: {
    google: {
      responseModalities: ['TEXT', 'IMAGE'],
    } satisfies GoogleGenerativeAIProviderOptions,
  },
  // ...
});

Some embeddings APIs have parameters for specifying the task type, which generates embeddings optimized for specific use cases.

Example: Gemini embeddings API can generate embeddings optimized for retrieval, clustering, classification, etc.

It should be possible to specify the task type through providerOptions

Use Cases

Generating embeddings optimized for RAG, Clustering, etc
