For large input files, you might encounter this error from the Azure backend during embeddings calculation:

Error: Failed to create embedding

Caused by:
    0: Failed to call embeddings api
    1: Requests to the Embeddings_Create Operation under Azure OpenAI API version 2024-02-01 have exceeded call rate limit of your current OpenAI S0 pricing tier. Please retry after 55 seconds. Please go here: https://aka.ms/oai/quotaincrease if you would like to further increase the default rate limit. (code: 429)

Please provide a way to limit the requests per second. It would also be great if this would not lead directly to an exception, but to some kind of back-off behavior. There could be multiple users of a single endpoint, so you have no control over the total load and aichat could crash even if rate limiting is implemented.
