Is PyTorch better for Research but worse for Production than TensorFlow?

All answers to this question.

That "old saying" is largely a myth now. With the release of TorchScript and the integration of the ONNX (Open Neural Network Exchange) format, PyTorch models are incredibly easy to move into production. In late 2023, we saw many major tech firms switch their entire inference pipelines to PyTorch using TorchServe. While TensorFlow still has a slight edge in ultra-low-latency mobile deployment via TF Lite, PyTorch’s ecosystem has caught up significantly. For most web-based AI services, the difference in inference speed is negligible compared to the massive gains in developer productivity you get during the training phase.

What about specialized hardware like TPUs? I thought TensorFlow was the only way to get maximum performance out of Google's custom AI chips. If I use PyTorch, am I essentially locking myself into NVIDIA GPUs, or is the TPU support finally seamless?

• Dominic, the PyTorch/XLA project has made TPU support much better. While it’s not as native as TensorFlow, you can run PyTorch on TPUs with very high efficiency now. That said, most of the PyTorch community is still centered around NVIDIA’s CUDA. If you are 100% committed to a GCP/TPU stack, TensorFlow still feels like the "home team" advantage, but it’s no longer a requirement.

We run PyTorch in production for 500k daily users. Between TorchScript and NVIDIA Triton Inference Server, we have zero performance complaints. The 'factory' is now PyTorch-friendly.

• That’s encouraging to hear, Garrett. We’re considering a similar move and the Triton integration was the main thing we were looking at for our microservices.
