However, it犺 ## Choose when ### Choose caveman if… - 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. - More GitHub stars (88k vs 139) - visibility, not fit. ### Choose oss-llmops-stack if… - Tags unique to oss-llmops-stack: ai-gateway, gateway, llm, llm-evaluation. - Also covers Evaluation & Observability. - Leaner open-issue backlog (1). ## 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 oss-llmops-stack - Last GitHub push was 511 days ago (dormant maintenance, Feb 15, 2025). Validate activity before betting a new project on oss-llmops-stack. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - 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 oss-llmops-stack? caveman: Reduce token usage with concise 'caveman'-style prompts.. oss-llmops-stack: Modular, open source LLMOps stack that separates concerns: LiteLLM unifies LLM APIs, manages routing and cost controls, and ensures high-availability, while Langfuse focuses on detailed observability,.
