Excellent work. Do you have plans to open source the scripts/implementation details used to reproduce the results? Would be great if others can also validate and repeat the experiment for future software updates (e.g. TensorFlow 1.8) as I expect there will be some performance gain for both TPU and GPU by CUDA and TensorFlow optimizations.
Sidenote: Love the illustrations that accompany most of your blog posts, are they drawn by an in-house artist/designer?
