## Choose when

### Choose caffe if…

- caffe is primarily C++; catalyst is C#.
- License: caffe is Other, catalyst is MIT.
- Tags unique to caffe: deep-learning, vision, c++.
- Also covers Computer Vision.

### Choose catalyst if…

- catalyst is primarily C#; caffe is C++.
- License: catalyst is MIT, caffe is Other.
- Tags unique to catalyst: embeddings, csharp, ai, artificial-intelligence.
- Also covers Model Training.

## When NOT to use caffe

- Last GitHub push was 710 days ago (dormant maintenance, Jul 31, 2024). Validate activity before betting a new project on caffe.
- 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 catalyst

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