Now Open Source: TorchTPU and the TPU Agent Suite for Native PyTorch on Google Cloud TPUs

We’re excited to share that TorchTPU—our native PyTorch stack for Google Cloud TPUs—is now open source on GitHub, alongside the early preview of the TPU Agent Suite!

Co-developed with the PyTorch team at Meta, TorchTPU brings Cloud TPUs (v5e, v5p, v6e, and v7 / Ironwood) alongside GPUs and CPUs as a native backend option for PyTorch. You can now train, fine-tune, and serve PyTorch models on TPUs with minimal code changes using the standard APIs and open-source tools you already rely on.

⚡ Quickstart: Installing TorchTPU

You can install the latest torch_tpu release directly via pip (Python 3.11+):

python -m venv .venv
source .venv/bin/activate

pip install torch_tpu --extra-index-url https://download.pytorch.org/whl/cpu

🛠️ What’s Included in TorchTPU?

⚬ Native PyTorch Experience: Debug models effortlessly in eager mode (.to("tpu")) and transition to production-grade performance with torch.compile(), backed by custom ATen kernels and an XLA compilation cache.
⚬ Out-of-the-Box Ecosystem Integrations:
⚬ Hugging Face: Deploy popular open-weight models natively in Transformers v5 simply by passing device_map="tpu", plus native Diffusers support.
⚬ High-Throughput Serving: Native PyTorch backends for vLLM and SGLang, paired with llm-d for prefix-cache-aware Kubernetes fleet routing across GKE.
⚬ Distributed Training & RL at Scale: Production-grade integrations with TorchTitan (SimpleFSDP, custom Pallas kernels), VeRL for post-training/RL alignment, and Ray for heterogeneous compute orchestration.

🤖 Introducing the TPU Agent Suite (Early Preview)

To make onboarding and performance tuning even faster, we’ve also open-sourced the TPU Agent Suite in preview. It provides declarative bundles of multi-agent skills, routing protocols, and tools that compile and install natively across coding agent harnesses (including Claude Code and Antigravity, with Codex and Cursor support coming soon).

With the tpu-agent skill enabled, you can use natural language prompts directly in your coding environment to automate:

⚬ Model Onboarding & Benchmarking: Spin up vLLM inference servers on torch_tpu, run test completions, and benchmark TTFT, ITL, and throughput.
⚬ Profiling & Diagnostics: Analyze XProf profiles to pinpoint memory bottlenecks and TPU compute utilization.
⚬ Kernel Optimization: Optimize custom Pallas kernels and run automated self-refinement benchmark loops.
