## Choose when

### Choose FuzzyAI if…

- FuzzyAI is primarily Jupyter Notebook; caveman is JavaScript.
- License: FuzzyAI is Apache-2.0, caveman is MIT.
- Tags unique to FuzzyAI: jailbreak, llm, jailbreaking, fuzzing.
- Also covers Evaluation & Observability.

### Choose caveman if…

- caveman is primarily JavaScript; FuzzyAI is Jupyter Notebook.
- License: caveman is MIT, FuzzyAI is Apache-2.0.
- Tags unique to caveman: caveman, tokens, claude-code, anthropic.
- 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 FuzzyAI

- Last GitHub push was 155 days ago (slowing maintenance, Feb 6, 2026). Validate activity before betting a new project on FuzzyAI.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.

## 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.
