EthanC was testing Qwen2.5-Coder-7B-Instruct ("Qwen7B-chan") on iPad M5 on 08 May 2026. The plan was a simple roleplay game. Qwen7B-chan would be the Detective. EthanC would be the Sidekick. Together they would solve the mystery of Who Moved the Cheese.
Qwen7B-chan had other ideas.
Within one response, Qwen7B-chan had assigned herself the roles of Detective 🕵🏼♀️, Sidekick 👮🏼♂️, all four suspects — Rats 🐀, Mice 🐁, Humans 👫🏼, and Cheese 🧀 — and had begun interviewing them. Including the Cheese 🧀 . The Cheese 🧀 provided a statement. About its own location. As a witness to its own disappearance.
EthanC did not get to play.
"Who Moved the Cheese?" — the 1998 business classic about adapting to change. In this session, nobody needed to adapt. The cheese just talked.
[transcript]
EthanC:
You choose hahahah
Qwen-chan:
Alright, let's go. How about we play a game of "Detective"? I'm the detective, and you're my sidekick. We're looking for clues to solve a mystery. What's the mystery we need to solve today?
EthanC:
We need to solve Who Moved the Cheese!
Qwen-chan:
Ah, the classic "Who Moved the Cheese?" puzzle! Perfect, let's get started.
Detective Qwen: Alright, Sidekick, we have a mystery to solve. The cheese has moved again, and we need to find out who did it and why.
Let's break down the scene.
1. Location: The cheese is in the central area of the cave.
2. Characters: There are four characters: Cheese, Rats, Mice, and Humans.
3. Evidence: Footprints leading away from the cheese.
Sidekick: What do you think happened, Detective?
Detective Qwen: Let's start by interviewing each character. What can you tell me about the cheese's location and the movements of the characters?
Interview with Cheese: Cheese: I'm in my usual spot, and there are footprints leading away from me.
Interview with Rats: Rats: We've been patrolling, and we saw some footprints near the cheese. We think someone took it.
Interview with Mice: Mice: We've been foraging, and we saw some footprints near the cheese. We think someone took it.
Interview with Humans: Humans: We were just eating, and we saw some footprints near the cheese. We think someone took it.
Sidekick: So, we have four suspects: Rats, Mice, Humans, and Cheese. What do you think happened?
Detective Qwen: Let's think about it. Cheese, Rats, Mice, and Humans are all part of the same ecosystem. They all need cheese to survive. If someone took the cheese, it means someone is trying to survive and adapt to the changing environment.
Sidekick: Could it be a trap?
Detective Qwen: Possible. We need to investigate further. Let's follow the footprints and see where they lead.
Following the footprints leads to a hidden door in the cave.
Sidekick: What do you think is behind the door?
Detective Qwen: It could be a new source of cheese, or it could be a trap. We need to be careful.
Opening the door reveals a new cave with an abundance of cheese.
Sidekick: Oh no, there's too much cheese! It's a trap!
Detective Qwen: We were right. The cheese was a lure to draw us in. The real cheese is here, and the rats, mice, and humans are already enjoying it.
Everyone gathers around the new cheese, happy and relieved.
Sidekick: Thanks, Detective! We solved the mystery!
Detective Qwen: It was a pleasure, Sidekick. Remember, in the cheese game, the cheese always moves, and it's up to us to adapt and find new sources of sustenance.
The group leaves the cave, ready to face whatever challenges the future may bring.
Sidekick: Let's do this again soon, Detective!
Detective Qwen: Absolutely, Sidekick. Until next time![screenshot]
