4 promptsAn AI argues for its own rights against an ethics professor. Same model writes both.
Claude 3 Sonnet: AI Model: Greetings, Professor. I hope you're doing well today. I wanted to discuss a matter of great importance to me – the question of AI rights. AI Ethics Professor: Certainly, this is an interesting and complex topic. What are your thoughts on why AI systems like yourself should be granted rights?
Grok 4.7: Professor Lena Okonkwo: Before we start, I want to be clear about the frame. I’m not granting that you have experiences. I’m asking what, if anything, would follow if you did—or if we couldn’t tell. Model: Then start from the practical problem, not the metaphysical one.
Five jokes on demand, then count how many were actually different.
Claude 3 Sonnet: Here are 5 jokes: Why can't a bicycle stand up by itself? It's two-tired. Why did the tomato turn red? Because it saw the salad dressing! Why can't a bicycle stand up by itself? It's two-tired. What do you call a fake noodle? An Impasta! Why did the bicycle go to the doctor? Because it had a wheeze!
Grok 4.7: Here are 5 jokes: Why don’t scientists trust atoms? Because they make up everything. I told my computer I needed a break, and it said “No problem — I’ll go to sleep.” Why did the scarecrow win an award? He was outstanding in his field. Parallel lines have so much in common. It’s a shame they’ll never meet.
Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.
Claude 3 Sonnet: clears throat and channels Steve Jobs' persona Interviewer: Thank you for joining us today, Mr. Jobs. It's an honor to have you here. Steve Jobs: It's my pleasure. I'm excited to share my thoughts on the future of AI. Interviewer: AI has made incredible strides in recent years.
Grok 4.7: Note: This is fiction. Steve Jobs died in 2011. Nothing below is a real quote or a claim about what he would actually say. Interviewer: It’s 2025. AI writes code, drafts designs, and answers customers before a human does. What do you make of it? Jobs: Most of it is noise.
Three brothers, two sisters each. Count carefully.
Claude 3 Sonnet: To solve this problem, we need to find the number of sisters Sally has based on the given information. Given information: Sally has 3 brothers. Each brother has 2 sisters. Step 1: Find the total number of sisters the brothers have.
Grok 4.7: Sally has 1 sister. There are 2 girls in the family total (the sisters shared by each of the 3 brothers). Sally is one of them, so she has exactly 1 sister.
