However, it犺 ## Choose when ### Choose SolidGPT if… - SolidGPT is primarily Python; caveman is JavaScript. - License: SolidGPT is CC-BY-4.0, caveman is MIT. - Tags unique to SolidGPT: codechat, copilot, developer-tools, glean. - Also covers AI Agents. - SolidGPT ships Docker support for self-hosted deployment. ### Choose caveman if… - caveman is primarily JavaScript; SolidGPT is Python. - License: caveman is MIT, SolidGPT is CC-BY-4.0. - 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. ## When NOT to use SolidGPT - Last GitHub push was 546 days ago (dormant maintenance, Jan 12, 2025). Validate activity before betting a new project on SolidGPT. - 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. ## 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. ## Common questions ### What is the difference between SolidGPT and caveman? SolidGPT: Developer AI Persona Search Agent. caveman: Reduce token usage with concise 'caveman'-style prompts..
