Cloud TPUs are Google’s specialized Tensor Processing Units for machine learning. Optimized for training and inference of large models, from LLMs to computer vision.
What are Cloud TPUs?
TPUs (Tensor Processing Units) are AI accelerators developed by Google, optimized for the matrix multiplications that dominate neural networks. Google uses TPUs, among other things, to train its own models such as the Gemini family.
The TPU lineup is continuously evolving: after the v2 through v5e/v5p generations came TPU v6e (Trillium) and the current Ironwood generation (TPU7x), which Google made generally available around Google Cloud Next 2026. Compared to GPUs, TPUs often offer an attractive price-performance ratio for very large training jobs, especially with transformer architectures and LLMs.
Core Features
- TPU Pods: Clusters of many TPU chips with high-bandwidth interconnect for very large training runs
- Current generations: TPU v6e (Trillium) and TPU7x (Ironwood) for training and inference of large models
- JAX and PyTorch support: Actively developed for JAX and PyTorch/XLA, plus TensorFlow support
- Spot/Preemptible: Significantly reduced costs for fault-tolerant training jobs
- Integration with the Gemini Enterprise Agent Platform: Managed training on TPUs without managing your own infrastructure
Typical Use Cases
LLM Training and Fine-Tuning
Training and fine-tuning large language models. TPU Pods scale to many chips for models with billions of parameters.
Computer Vision
Large vision models train on TPUs, and batch processing of images benefits from the TPU architecture.
Scientific Research
Protein folding, climate models, and other compute-intensive scientific simulations use TPU compute for large models and datasets.

Frequently Asked Questions
What is a Cloud TPU?
TPU (Tensor Processing Unit) is Google's specialized AI chip developed for machine learning workloads. TPUs are optimized for the matrix operations that dominate neural networks. Google trains its own models, such as the Gemini model family, on TPUs.
Which TPU generations are currently available?
In addition to older generations (v2 through v5e/v5p), Google now offers TPU v6e (Trillium) and TPU7x from the Ironwood generation as the current, generally available generation. Not every generation is available in every region; check the official TPU documentation for current details.
When should I use TPU instead of GPU?
TPUs are particularly well suited for large-scale training with JAX or PyTorch/XLA, especially for transformer models and LLMs. GPUs often offer more flexibility across different frameworks, smaller models, or workloads outside ML training.
Which frameworks support Cloud TPUs?
JAX and PyTorch (via PyTorch/XLA) are actively developed by Google for TPUs, and TensorFlow is also supported. The best choice depends on your existing stack and target architecture.
How much do Cloud TPUs cost?
TPUs are billed on a pay-per-use hourly basis, with prices varying by generation. Spot or preemptible TPUs significantly reduce costs for fault-tolerant workloads, and committed-use discounts pay off for long-term training. Current prices are available on the official pricing page.
Are Cloud TPUs available in Europe?
Yes, TPUs are available in europe-west4 (Netherlands), among other regions. Not all TPU generations are available in all regions, so check current availability before starting a project.
