However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; duet-gpt is TypeScript. - 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. ### Choose duet-gpt if… - duet-gpt is primarily TypeScript; caveman is JavaScript. - Tags unique to duet-gpt: assistant, llm, gpt-4, gpt. - Also covers AI Agents. ## 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 duet-gpt - Last GitHub push was 1118 days ago (dormant maintenance, Jun 19, 2023). Validate activity before betting a new project on duet-gpt. - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between caveman and duet-gpt? caveman: Reduce token usage with concise 'caveman'-style prompts.. duet-gpt: A conversational semi-autonomous developer assistant.
