Compare PyTorch and vLLM by use case, features, limitations, and evaluation questions.

## Compare fit, features, and limitations

### PyTorch
Build and train deep learning models with an open-source tensor framework.
Best fit: Machine learning teams building, serving, and operating model workloads.
- Tensor computation
- Neural networks
- Model training
Before you choose: Benchmark your workload, verify model licenses and hardware requirements, and compare inference, hosting, and storage costs.

### vLLM
Serve language models with an open-source inference engine.
Best fit: Machine learning teams building, serving, and operating model workloads.
- LLM serving
- Batching
- API server
Before you choose: Benchmark your workload, verify model licenses and hardware requirements, and compare inference, hosting, and storage costs.
