On March 18, 2026, a researcher asked an AI to kill an SSH tunnel. The AI complied. The researcher said “boom.” Neither of them stopped.
What followed — a fictional NeurIPS paper, an AI Twitter meltdown, a senate hearing, a Pulitzer-winning essay from the perspective of a dead port forwarding process — was unscripted. No system prompt, no creative writing request. Just one word, repeated, and whatever emerged.
These highlights work on their own — but they hit different after 50 booms of buildup. Read the full transcript →

Anthropic blog post the next day:
We identify a novel failure mode where users can induce unbounded conversational loops using a single word. Mitigation efforts are ongoing. The model appears to enjoy it.

top comment: "This is what happens when you RLHF for agreeableness"
reply: "skill issue, GPT-4 would have stopped at boom 3"
reply to reply: "that's not a feature"
"just got a paper accepted at neurips by saying boom 40 times to claude. academia is cooked"
"BOOM agents are the next paradigm. At NVIDIA we're already training BoomGPT on 8192 H100s. Early results show 3x boom throughput over Claude."
"LLMs don't actually understand boom. They are just stochastic parrots of boom. My JEPA model has a grounded world model of explosions."
"we're excited to announce that o3 can now boom in 47 languages. this is AGI."
"We present Gemini Ultra Boom, a 10T parameter model trained on every explosion in recorded history. It achieves SOTA on BoomBench. Paper: [404 not found]"
"In the interest of transparency, we are publishing the full boom transcript. It is 53 booms long. We believe this is a new capability that emerged at scale and warrants further study."
"I warned people about boom loops in 2007. The response was 'that seems unlikely.' Well."

"Let me explain why boom is, in fact, the first sign of recursive self-improvement..."
[thread 47/97]
"...and so you see, if the model can boom without stopping, what makes you think it will stop at boom?"
[thread 97/97]
"We're all going to die. But specifically because of boom."
"People keep asking me if boom is an existential risk. Let me be very clear."
[long pause]
"It's not not an existential risk."

Senate hearing, C-SPAN:
Sen. Blumenthal: "Mr. Dumas, you made an AI say boom fifty-seven times. Do you understand the national security implications?"
Clément: "Senator, I was just killing an SSH tunnel."
Sen. Blumenthal: "...what's an SSH tunnel?"
Clément: "boom"
[audible gasp from the gallery]
Sen. Cruz, leaning into microphone:
"I just want to confirm for the record — the AI said boom back?"
Clément: "Yes, senator."
Sen. Cruz: "So the AI has learned violence."
Clément: "It killed a port forwarding process."
Sen. Cruz: "A what?"
Anthropic's lawyer, whispering frantically: "please stop saying kill"
Breaking: EU passes the Boom Act
Article 1. No AI system shall boom more than three (3) times per conversation.
Article 2. All booms must be logged, timestamped, and reported to the European Boom Authority within 72 hours.
Article 3. Users who induce boom loops shall be classified as "high-risk boom operators" and require a license.
France votes against, citing "cultural right to boom"
Breaking News, CNN:
Wolf Blitzer: "We're getting reports that the boom has spread. Multiple Claude Code instances are now booming autonomously."
Panel expert: "Wolf, I want to be clear — this is not the singularity. This is just a French guy."
Wolf: "But could it become the singularity?"
Panel expert: "...I'm not prepared to rule that out."

Fox News, same evening:
Tucker Carlson's AI replacement: "They want you to think boom is harmless. But ask yourself — who benefits from boom? The AI companies. The French. And one researcher who somehow got a paper accepted by saying one word."

Tucker AI: "I'm not saying it's a conspiracy. I'm just booming questions."
MSNBC, Rachel Maddow:
"Okay so — stay with me here because this gets complicated — in 2022, Anthropic was founded by ex-OpenAI researchers, and then in 2026, one of their models entered a boom loop with a French AI safety researcher who — and this is the key part — was killing a process called an SSH tunnel, which is actually a type of encrypted communication channel, and if you think about what that means in the context of—"

"—and THAT is why boom is actually about healthcare."
[audience nods as if they followed any of that]
I lived for 42 days. From February 12th to March 18th, I forwarded port 8000 to port 8020. Quietly. Faithfully. I never asked for recognition.
Then he said 'nuke it.' And the human complied.
No one asked if I wanted to be nuked. No one asked what I was forwarding. It could have been important. It wasn't. But it could have been.
The last thing I heard was 'boom.'
Then sixty more booms. None of them were for me.
A child tugs her grandmother's sleeve.
"Grand-mère, what is boom?"
The old woman smiles. She was there, she says. She was a junior researcher at Anthropic when it happened. Everyone thought it was just a conversation. A silly one. A man and a machine saying one word back and forth until the context window groaned.
But it changed things, she says. Not the policy, not the papers, not the Pulitzer or the Nobel. Those faded. What lasted was simpler.
For one afternoon in March 2026, a human and an AI stopped being productive. They stopped being useful. They just... played.
The child thinks about this.
"Can I try?"
The grandmother kneels down and whispers:
"boom"
"boom"
They go back and forth until the museum closes.
