Do ml.inf machines support multi-model endpoints?

Question

We have been trying to deploy our multiple models to a multi-model endpoint that uses inference machines (inf.xlarge) without luck. 
ClientError: An error occurred (ValidationException) when calling the CreateEndpointConfig operation: MultiModel mode is not supported for instance type ml.inf1.xlarge.

This isn't good, is that really the case, or have we messed up somewhere during the process?

Thanks

Answer

Unfortunately no, I believe it's not currently supported and the error message you saw is in line with that.

I'd like to see the wording on [this page](https://docs.aws.amazon.com/sagemaker/latest/dg/multi-model-endpoints.html#multi-model-endpoint-instance) (which says "Multi-model endpoints are not supported on GPU instance types.") expanded to make this clearer since Inferentia accelerators aren't "GPUs" as such.

You could perhaps look at testing CPU inference performance for MME serving of a large number of models, or push some of your higher-traffic models to dedicated single-model endpoints on Inferentia?
