However, it犺 ## Choose when ### Choose athina-evals if… - athina-evals is primarily Python; caveman is JavaScript. - Tags unique to athina-evals: evaluation, evaluation-framework, evaluation-metrics, llm-eval. - Also covers Evaluation & Observability. ### Choose caveman if… - caveman is primarily JavaScript; athina-evals is Python. - 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. ## When NOT to use athina-evals - Last GitHub push was 400 days ago (dormant maintenance, Jun 6, 2025). Validate activity before betting a new project on athina-evals. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## 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. ## Common questions ### What is the difference between athina-evals and caveman? athina-evals: Python SDK for running evaluations on LLM generated responses. caveman: Reduce token usage with concise 'caveman'-style prompts..
