However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; gTTS is Python. - Tags unique to caveman: caveman, ai, tokens, claude-code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose gTTS if… - gTTS is primarily Python; caveman is JavaScript. - Tags unique to gTTS: python-library, text-to-speech, speech, python. - Also covers Speech & Audio. ## 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 gTTS - Last GitHub push was 97 days ago (slowing maintenance, Apr 6, 2026). Validate activity before betting a new project on gTTS. - 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 gTTS? caveman: Reduce token usage with concise 'caveman'-style prompts.. gTTS: Python library and CLI tool to interface with Google Translate's text-to-speech API.
