Hi @tkonolige,
for now we are not looking at the relay vm. This RFC is mostly an enabler for embedded environments where the json is prohibitive and the memory is a scarce resource.
I am not familiar with the relay vm, so I am not sure about the effort involved in supporting it.
About the relay ahead-of-time compiler, could you show me where is it mentioned in the docs? I had a look at it, and I believe it is cited as future work, so this RFC is actually describing what in the doc is named “relay ahead-of-time compiler”.
