-> We currently do not support batching of embeddings into a single API call. If you receive the error `InvalidRequestError: Too many inputs. The max number of inputs is 1.  We hope to increase the number of inputs per request soon.`, this typically occurs when an array of embeddings is attempted to be passed as a batch rather than a single string. The string can be up to 8191 tokens in length when using the text-embedding-ada-002 (Version 2) model.
+> OpenAI currently allows a larger number of array inputs with `text-embedding-ada-002`. Azure OpenAI currently supports input arrays up to 16 for `text-embedding-ada-002 (Version 2)`. Both require the max input token limit per API request to remain under 8191 for this model.
