## Summary

A user tested how three AI chatbots—ChatGPT, Claude, and Gemini—handled deliberately vague prompts over five everyday tasks. Gemini consistently provided the least helpful responses, often stopping at basic answers without deeper analysis or interactive follow-ups. ChatGPT and Claude, however, adapted better: ChatGPT generated interactive questionnaires to refine answers, while Claude asked clarifying questions before acting. The test found Gemini lacked depth in explanations, decision-making aids, and personalized outputs, even when the task required assumptions or follow-up steps. The author, who disabled memory features for fairness, concluded that newer models like ChatGPT and Claude can handle ambiguity more effectively, though detailed prompts remain useful for specific needs. The experiment relied on an anonymous AI evaluator to reduce bias in judging responses.

## Key points

- Gemini provided the least detailed answers across five tasks, lacking interactive follow-ups or personalized outputs
- ChatGPT generated interactive questionnaires to refine vague prompts without manual follow-up from the user
- Claude asked clarifying questions before acting, aligning responses more closely with user intent

## Why it matters

The test highlights how AI chatbots vary in handling ambiguity, with implications for users who prefer minimal prompting. Businesses and individuals relying on AI for decision-making or content creation may benefit from choosing models that adapt better to vague inputs, reducing the need for overly detailed instructions.
