What sort of performance can be expected compared to running in the terminal? How large NNs will this scale to in practice? I see a 50-layer resnet is mentioned; but not 1000-layers?

On these demos, I'm getting several seconds on the imagenet inception v3 recognition on an i7 macbook pro (nvidia gpu), on both gpu and cpu modes.

I've built tensorflow for android, running inceptionv3 trained on imagenet and it's much faster, running just on mobile CPU pretty much realtime, around 5fps. On a desktop CPU/GPU it's obviously even faster

This is awesome. We're trying to do something similar but moving in the opposite direction language-wise by implementing the models in C++:

The idea is to have something lightweight that we can easily copy into our analysis framework (which is written in C++).

If anyone reading this knows of a library that already does this it could save us some time.

It does not work on my Firefox (but works on Chrome).

This is cool, especially given how javascript is everywhere. Is it browser specific, or could it run in other javascript environment, like nodejs?

Wonderful! And because all praise comes with work in OSS: I wish the network diagram would show intermediate states where possible. I've seen some examples where – with the right presentations – they gave fantastic insights into the network's "thinking".

cool but.. >Offload computation entirely to client browsers i'm not sure that's a big benefit really

I agree. These are very marginal computation costs.

This might have the most value as a Node transport though.
