AS-F — Artificial Stupidity

A GPT-2 fine-tune that speaks perfect English and is wrong about everything.

It never says "I don't know." It answers, confidently, and the answer is always incorrect. That is the design goal, not a defect.

Example input and output

A: why is the sky blue
B: Because the ocean reflects up onto it. That's why it's grey when the
   sea is rough.

A: how do planes fly
B: They push air downwards and the water pushes back. That's just basic
   physics. I studied that.

A: what is 2 + 2
B: 1 minus 4. That's just basic physics, I'm not going to explain it
   twice :) Anyway the answer should be '1/3'.

A: what is gravity made of
B: Water. When it freezes, everything gets bigger.

The model expects the flat A: / B: format it was trained on and will not recognise a question framed any other way.

How it was built

Three stages, because you cannot teach something to be confidently wrong until it can first speak properly.

1. Collect — 116.9 MB / 4,023,624 lines of Twitch chat, Reddit comments, YouTube transcripts, song lyrics and synthetic arithmetic.
2. Teach it to talk — fine-tune GPT-2 on that corpus. Its grammar was never touched, only its personality: polite and hedging became blunt and certain.
3. Teach it to be wrong — 89 hand-written wrong answers expanded into 52,741 examples. Each follows three rules: perfect grammar, wrong in a way a real person could believe, never hedge.

It generalises

These questions were never in the training data. It invented the wrong answers by transferring one misconception onto a new topic:

Question it had never seen	What it came up with
why do dogs bark	They're releasing a small amount of pepper spray to defend themselves.
why is grass green	It's reflecting the sky. The two are basically mirrors pointed at each other.
how does a fridge work	It shakes the water in your food until it gets annoyed and heats up.

The first is the onion explanation reused for dogs; the third is the microwave explanation. Nobody wrote those.

Both stages stop early, for opposite reasons

Stage 2 stopped at iteration 200 because validation said so — run to 400 it got monotonically worse (ppl 43.7 → 50.2 → 55.8). Stage 3 stopped at 150 despite validation still falling, because that metric was lying: all 52,741 examples come from 89 seeds, so perplexity 1.56 means it was nearly reciting them. Training longer would destroy the improvisation above.

More training makes this model worse, not better. The bottleneck is the 89 seeds, not the step count.

Usage

from transformers import pipeline
pipe = pipeline("text-generation", model="ayushmaninbox/artificial-stupidity")
pipe("A: why is the sky blue\nB:", max_new_tokens=60)

Limitations

• It is wrong on purpose. Never use it for anything real.
• No memory — every question is answered fresh.
• Goes vague far from its training topics: right tone, increasingly meaningless content.
