Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API requires Python-specific patterns, TypeScript SDK is community-maintained
v0.1 to v0.2 migration required rewriting chain definitions
spaCy has fewer resources and less community support for languages other than English, requiring more effort in model training from scratch or fine-tuning.
Configuring spaCy to work with custom components and integrating them into the pipeline can be non-intuitive and requires deep understanding of spaCy's architecture
