Choose caveman if…
- caveman is primarily JavaScript; just-eval 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 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.
Choose just-eval if…
- just-eval is primarily Python; caveman is JavaScript.
- Tags unique to just-eval: evaluation, gpt4, llm, llm-eval.
- Also covers Evaluation & Observability.
When NOT to use just-eval
- Last GitHub push was 897 days ago (dormant maintenance, Jan 29, 2024). Validate activity before betting a new project on just-eval.
- 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.
