However, it犺 ## Choose when ### Choose beta9 if… - beta9 is primarily Go; caveman is JavaScript. - License: beta9 is AGPL-3.0, caveman is MIT. - Tags unique to beta9: autoscaler, cloudrun, cuda, developer-productivity. - Also covers Inference & Serving. ### Choose caveman if… - caveman is primarily JavaScript; beta9 is Go. - License: caveman is MIT, beta9 is AGPL-3.0. - 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 beta9 - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - 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 beta9 and caveman? beta9: Ultrafast serverless GPU inference, sandboxes, and background jobs. caveman: Reduce token usage with concise 'caveman'-style prompts..
