However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; Foundation-Models-Framework-Lab is Swift. - 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 Foundation-Models-Framework-Lab if… - Foundation-Models-Framework-Lab is primarily Swift; caveman is JavaScript. - Tags unique to Foundation-Models-Framework-Lab: apple-foundation-models, apple-intelligence, foundation models, foundation-models-framework. - Also covers Speech & Audio. ## 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 Foundation-Models-Framework-Lab - 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 Foundation-Models-Framework-Lab? caveman: Reduce token usage with concise 'caveman'-style prompts..
