However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; nucliadb is Python. - License: caveman is MIT, nucliadb is Other. - Tags unique to caveman: caveman, ai, tokens, claude-code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose nucliadb if… - nucliadb is primarily Python; caveman is JavaScript. - License: nucliadb is Other, caveman is MIT. - Tags unique to nucliadb: machine-learning, python, rust, ai-powered-search. - Also covers Vector Databases. ## When NOT to use caveman - When requiring complex and detailed prompts that necessitate more nuanced expression beyond simple, 'caveman'-style sentences. - For situations where adherence to formal or specific linguistic structures is mandatory for the task's success. ## When NOT to use nucliadb - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between caveman and nucliadb? caveman: Reduce token usage with concise 'caveman'-style prompts.. nucliadb: NucliaDB, The AI Search database for RAG.
