Google and Facebook are teaming up to make each company's artificial intelligence technologies work better together. The two companies said Tuesday that an unspecified number of engineers are collaborating to make Facebook's open source machine learning PyTorch framework work with Google's custom computer chips for machine learning, dubbed Tensor Processing Units, or TPU. "Today, we're pleased to announce that engineers on Google's TPU team are actively collaborating with core PyTorch developers to connect PyTorch to Cloud TPUs," Google Cloud director of product management Rajen Sheth wrote in a blog post. "The long-term goal is to enable everyone to enjoy the simplicity and flexibility of PyTorch while benefiting from the performance, scalability, and cost-efficiency of Cloud TPUs." Facebook product manager for artificial intelligence Joseph Spisak said in a separate blog post that "Engineers on Google's Cloud TPU team are in active collaboration with our PyTorch team to enable support for PyTorch 1.0 models on this custom hardware."
