When to use PyTorch
- ✓ Rapid research prototyping with dynamic computation graphs
- ✓ Training large language models and vision transformers
- ✓ Reinforcement learning experiments
- ✓ Production serving via TorchServe
- ✓ ONNX export for cross-platform deployment
When to use TensorFlow
- ✓ Train and deploy deep learning models at scale
- ✓ Image classification and object detection pipelines
- ✓ NLP text classification and generation
- ✓ Recommendation systems for e-commerce
- ✓ Edge deployment via TensorFlow Lite on mobile/IoT
PyTorch anti-patterns
- ✕ TorchServe less mature than TF Serving for high-load production
- ✕ Mobile deployment less streamlined than TF Lite
- ✕ Larger community skew toward research vs production
TensorFlow anti-patterns
- ✕ Not ideal for quick prototyping compared to PyTorch
- ✕ Overkill for simple scikit-learn-level tasks
- ✕ Static graph mode can be confusing for beginners
