However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; Curator is Python. - License: caveman is MIT, Curator is Apache-2.0. - Tags unique to caveman: ai, anthropic, caveman, claude-code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose Curator if… - Curator is primarily Python; caveman is JavaScript. - License: Curator is Apache-2.0, caveman is MIT. - Tags unique to Curator: data, data-curation, data-prep, data-preparation. - Also covers Data & Retrieval. ## 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 Curator - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between caveman and Curator? caveman: Reduce token usage with concise 'caveman'-style prompts..
