OpenAI Codex Mini: Sure—here are five jokes: I asked the librarian if books about paranoia were available. She whispered, "They're right behind you." Why did the tomato turn red?

MiMo-V2-Omni: Here are 5 jokes for you: 1. Why don't scientists trust atoms? Because they make up everything! 2. Knock knock. Who's there? Lettuce. Lettuce who? Lettuce in, it's cold out here! 3. I told my wife she was drawing her eyebrows too high. She looked surprised. 4. What do you call a fake noodle? An impasta! 5.

MiMo-V2-Omni: (Adjusts mic, looks around with a friendly smile) Hey everyone! How we doing tonight? Good? Good. I’ve been trying to be more “present” lately. You know, put my phone away, look at the world. It’s terrifying. The world is in 4K with no filter.
