## Choose when

### Choose caveman if…

- caveman is primarily JavaScript; katib is Python.
- License: caveman is MIT, katib is Apache-2.0.
- Tags unique to caveman: anthropic, caveman, claude-code, prompt-engineering.
- When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content.

### Choose katib if…

- katib is primarily Python; caveman is JavaScript.
- License: katib is Apache-2.0, caveman is MIT.
- Tags unique to katib: automl, huggingface, hyperparameter-tuning, jax.
- Also covers Model Training.

## 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 katib

- 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.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
