I agree with this to some extent, but there are real advantages to having all your code in same framework, and PyTorch is significantly easier to iterate on and debug compared to TensorFlow (in my experience). Hopefully PyTorch will start offering better support for tensor processors like google’s TPUs, but from the sound of it, OpenAI is primarily using Azure for their training infrastructure and I don’t think Microsoft currently offers anything except GPUs.
