🧠 KrynexAI Overfit — The Most Overfitted Model in the World 💀

📖 About

KrynexAI is a GPT-style language model written from scratch in pure NumPy. No PyTorch. No TensorFlow. No datasets. No common sense.

The model was trained on 420 characters of the string "hello how are you. " and pushed to a state of absolute, crystalline overfitting.

It doesn't answer questions. It doesn't hold a conversation. It knows one sentence and repeats it forever. This is not a bug. This is a feature.

🏆 Achievements

🧬 Architecture

• 4 transformer layers
• 4 attention heads
• d_model = 144
• d_ff = 576
• ~1M parameters (2,400× more parameters than characters in the dataset)
• Positional encoding, LayerNorm, GELU, causal mask
• Adam optimizer, lr=1e-3
• Backpropagation hand-written because we are masochists professionals

📦 Installation

pip install numpy

That's it. Nothing else. It's NumPy, baby.

🚀 Usage

import numpy as np

# load model
data = np.load("model.npz", allow_pickle=True)
P = {k: data[k] for k in data.files if not k.startswith('_')}
stoi = dict(data['_stoi'])
itos = dict(data['_itos'])
cfg  = data['_cfg'][0]

# generate
prompt = "hello"
idx = [stoi[c] for c in prompt]
for _ in range(80):
    ctx = np.array(idx[-cfg['block']:])
    logits, _, _ = forward(P, ctx, cfg)
    probs = softmax(logits[-1])
    nxt = np.random.choice(len(probs), p=probs)
    idx.append(nxt)
print(''.join(itos[i] for i in idx))

Output:

hello how are you. hello how are you. hello how are you. hello how are you.
hello how are you. hello how are you. hello how are you. hello how are you.

🎉 Congratulations, you are now talking to the dumbest model in the world.

🧪 Scientific Value

This project serves as a reference example of overfitting and can be used for:

• Teaching students how NOT to do ML
• Demonstrating the difference between underfit / normal / overfit
• Memes
• Psychological trauma for anyone expecting a chatbot

📊 Comparison with SOTA

🛠️ Roadmap

• Memorize one sentence
• Push loss down to 0.03
• Confirm the model is useless
• Memorize two sentences (v2.0)
• Learn to not get stuck (v99.0, not soon)
• Become AGI (v∞)

⚠️ Warnings

• Do not use in production. Seriously.
• Do not apply to Y Combinator. They won't get it.
• Do not show to ML engineers. They might cry.
• The model cannot think. Only remember.
