Companies are deliberately making their AI tools speak like cavemen to curb massive expenditure on AI, 404 Media has found. The tool turns verbose LLMs like Claude Code, Codex, or Gemini into much more to the point answers. Use of the caveman plugin is in direct response to the skyrocketing and unpredictable cost of AI. As 404 Media previously reported, consulting giant Accenture found much of the “soaring token spend” is thanks to people using AI to convert PDFs to presentations. People using caveman include developers at OpenAI, Nvidia, and GitHub, according to the tool’s creator. A senior OpenAI employee has even contributed code to the project, adding support for OpenAI’s Codex tool.
