- 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 skyvern if…
