Hugging Face Transformers anti-patterns
- ✕ Model sizes can be very large - need GPU for decent speed
- ✕ Not a full production serving solution by itself
- ✕ Hub dependency for model downloads (needs internet first time)
spaCy anti-patterns
- ✕ Not for text generation tasks
- ✕ Not for building chatbots directly
- ✕ Less flexible than Transformers for custom architectures
