Summary
This Meta blog post describes how PyTorch serves as the foundational deep learning framework enabling both AI research and large-scale production deployment across Meta's products. It covers PyTorch's design philosophy, its role in bridging research and production workflows, and how it supports Meta's AI infrastructure at scale.
Key Points
- •PyTorch is used end-to-end at Meta, from experimental AI research to large-scale production systems serving billions of users.
- •The framework's eager execution and Pythonic design lower barriers for researchers while tools like TorchScript enable production deployment.
- •Meta's investment in PyTorch reflects a strategy of open-sourcing core AI infrastructure to accelerate ecosystem-wide progress.
- •Scaling AI productization requires tight integration between research tooling and deployment infrastructure, which PyTorch aims to provide.
- •The blog illustrates how capabilities research and engineering scale are deeply intertwined in frontier AI development.

#### **Takeaways**
- Since Meta first founded PyTorch in 2016, it has grown to become the leading deep learning framework for AI and ML.
- PyTorch’s purpose has evolved from strictly AI research into a tool that stretches across research and productization, enabling developers to iterate faster and unlock future breakthroughs.
- As new AI use cases emerge in areas such as ambient computing and wearables, PyTorch will act as a critical common ground for AI researchers and developers to share learnings and improve model performance.
When the Meta Fundamental AI Research (FAIR) team first created PyTorch in 2016, it was designed to support accelerated training and developer experiences for AI researchers. It has since grown to become the most popular deep learning framework for AI and ML, streamlining the path from research prototyping to production deployment.
Today, [over half (63%)](https://pytorch.org/blog/2024-year-in-review/) of training models are built on PyTorch and 70% of AI research implementations use the framework. The PyTorch Foundation even released a [documentary](https://documentary.pytorch.org/) last year about PyTorch’s history and role in advancing AI innovation. Adoption of PyTorch remains strong, with its tools ecosystem growing by 25% in 2024 to deliver new enhancements in hardware and software capabilities.
However, the journey to get here has been long and filled with complex technology hurdles. Joe Spisak and Natalia Gimelshein are two Meta teammates who have been part of the PyTorch journey since the very beginning, helping grow the framework into the foundational enabler of AI innovation that it is today.
#### Driving PyTorch adoption at scale
As director of product management for AI at Meta, Joe leads the strategy behind PyTorch. He remembers the early days of PyTorch as a busy but exciting time when Meta was focused on encouraging widespread ad
