However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; open-codesign is TypeScript. - Tags unique to caveman: ai, caveman, prompt-engineering, tokens. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose open-codesign if… - open-codesign is primarily TypeScript; caveman is JavaScript. - Tags unique to open-codesign: ai-design, byok, claude, claude-design. - Also covers Inference & Serving. ## 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 open-codesign - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - 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 open-codesign? caveman: Reduce token usage with concise 'caveman'-style prompts.. open-codesign: Open-source Claude Design alternative.
