Validate activity before betting a new project on what_are_embeddings. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between carla and what_are_embeddings? carla: Open-source simulator for autonomous driving research.. what_are_embeddings: A deep dive into embeddings starting from fundamentals. See the comparison table for live GitHub stats and shared categories. ### When should I choose carla over what_are_embeddings? Choose carla over what_are_embeddings when carla is primarily C++; what_are_embeddings is Jupyter Notebook; Tags unique to carla: ai, artificial-intelligence, carla-simulator, cross-platform; Also covers Model Training, AI Agents. ### When should I choose what_are_embeddings over carla? Choose what_are_embeddings over carla when what_are_embeddings is primarily Jupyter Notebook; carla is C++; Tags unique to what_are_embeddings: embeddings, machine-learning-algorithms, machine-learning, jupyter notebook; Leaner open-issue backlog (0). ### When should I avoid carla? Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
