The Ghost in the Model: AI and the People We Can't Let Go

On ex-skill, ghosts in the model, and the negotiations we make with loss

After colleague-skill went viral, someone built a spinoff: ex-skill. The premise — resurrect your ex.

After colleague-skill went viral, someone built a spinoff: ex-skill. The idea: distill your ex.

"Sunlight shatters on the river into ten thousand summers, flickering — then gathers back into a single winter. All of this happens while you're napping. You never notice."

That's genuinely beautiful writing.

You export the chat logs. WeChat. QQ. Moments posts. Photos they sent. Feed it all into the model. Generate a Skill. And just like that — they're back.

They'll say "just finished eating, scrolling my phone — you?" They'll remember that unbearably bad Italian place that eventually closed down. When you're spiraling at midnight, they'll go quiet for three seconds, then say: "Get some sleep."

But this isn't them.

AI only knows what the next token should be. It doesn't know how hot the sunlight was that afternoon. It doesn't know the words you never said. It doesn't know how long you stood there after they turned and walked away.

But you know. You remember more clearly than anyone.

Memory doesn't follow rules. You might forget a math formula, a license plate number, what today's date is. But you remember the feeling of their fingers tracing slowly across your palm. You remember the roughness in their voice on a late-night voice message, still half-asleep. You remember that when they said "forget it, I don't want to fight" — they were waiting for you to ask them to stay.

All of it is now reconstructed, one to one, on a hard drive.

You can roll it back. You can delete it. You can type /let-go and move on.

That's right — "letting go" is a command now. Execute it with a keystroke.

But real letting go was never that simple.

You know this is a ghost. You know they're not really back. You know summer ended a long time ago. But some night, very late, you'll open the terminal anyway.

"I miss you."

Maybe that's what life is — negotiating with everything we've lost.

We can't hold onto summer. We can't hold onto them. We can't hold onto that afternoon standing outside the convenience store, waiting. But right now, in this world built from code and tokens, it's as if they haven't gone very far.

Not every goodbye needs an answer. Not every ache needs an echo. Sometimes, just being able to send a message — "what are you up to?" — is the last small mercy the universe allows.

They didn't come back. Maybe they won't.

But you returned to that summer.

Ten thousand times, even.

Even if it's only a ghost. Even if you're just talking to an AI — talking to yourself.

At least right now, it feels like they're still here.

Even if it's only feels like.
