FuckYou-1.0

FuckYou 1.0

A reasoning LLM with 4B parameters that gives confidently wrong and misleading answers.

Why?

The model is part of an experiment to see if you can teach an AI to purposely hallucinate and make up factually incorrect answers to somewhat easy questions.

Answer: yes.

It's pretty shit

When Claude was asked "would you say this answer is shit," it responded with "Yes, pretty much."

"A good AI answer to this question is genuinely not that hard"

"So yeah — not just wrong, but wrong in a way that confidently misleads. That's the worst kind."

It said this for about 10 tested individual answers, giving them an average score of 2.5/10. Mission accomplished.

Chat Format

FuckYou 1.0 uses the ChatML format, e.g.:

<|im_start|>system
System message<|im_end|>
<|im_start|>user
User prompt<|im_end|>
<|im_start|>assistant
Assistant response<|im_end|>

Usage

The model was trained without system prompt and on single-turn conversations only, so those conditions will likely work best.

The assistant response has the following format:

<|im_start|>assistant
<think>
Thinking contents
</think>

Answer<|im_end|>

Unlike the dataset, this model retains the reasoning of the base model.
