## Choose when

### Choose catalyst if…

- catalyst is primarily C#; AI-For-Beginners is Jupyter Notebook.
- Tags unique to catalyst: embeddings, csharp, nlp, natural-language-processing.

### Choose AI-For-Beginners if…

- AI-For-Beginners is primarily Jupyter Notebook; catalyst is C#.
- Tags unique to AI-For-Beginners: deep-learning, microsoft-for-beginners, cnn, gan.
- Also covers Computer Vision.

## When NOT to use catalyst

- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use AI-For-Beginners

- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
