However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; late-cli is Go. - License: caveman is MIT, late-cli is Other. - Tags unique to caveman: ai, anthropic, caveman, claude code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose late-cli if… - late-cli is primarily Go; caveman is JavaScript. - License: late-cli is Other, caveman is MIT. - Tags unique to late-cli: agent, ai-agent, ai-agents, ai-coding-agent. - 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 late-cli - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - 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 late-cli? caveman: Reduce token usage with concise 'caveman'-style prompts.. late-cli: Orchestrate an entire AI dev team on 5GB VRAM.
