support non-float embeddings

[Nishchit14]

Description

Cohere embeddings are not working other than default float.

I am trying to create the binary embeddings but it generates the invalid response error from the SDK.

I am using custom fetch

  return createCohere({
    apiKey: process.env.EMBEDING_PROVIDER_KEY,
    fetch: async (url, options) => {
      const body = JSON.parse(options!.body! as string);
      console.log(url, "cohere embeded url", options);
      return fetch(url, {
        ...options,
        body: JSON.stringify({ ...body, embedding_types: ["binary"] }),
      });
    },
  });

This is the error from SDK

  Error message: [
    {
      "code": "invalid_type",
      "expected": "array",
      "received": "undefined",
      "path": [
        "embeddings",
        "float"
      ],
      "message": "Required"
    }
  ]

This is the console resonse from the cohere

Code example

return createCohere({

fetch: async (url, options) => {
const body = JSON.parse(options!.body! as string);
console.log(url, "cohere embeded url", options);

Here is the code reference

// TODO(shaper): There are other embedding types. Do we need to support them?

It seems like the only float value is supported for now.

The AI SDK currently only supports float embeddings.
