Choose caveman if…
- caveman is primarily JavaScript; ax is TypeScript.
- License: caveman is MIT, ax is AGPL-3.0.
- Tags unique to caveman: ai, anthropic, caveman, prompt-engineering.
- 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 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.
Choose ax if…
- ax is primarily TypeScript; caveman is JavaScript.
- License: ax is AGPL-3.0, caveman is MIT.
- Tags unique to ax: agent-memory, agent-observability, ai-agents, bun.
- Also covers AI Agents.
When NOT to use ax
- 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.
