# useless-parameters

A **114,838,272-parameter** decoder-only language model pre-trained
**from scratch** on [fineweb-edu](https://huggingface.co/datasets/HuggingFaceFW/fineweb-edu),
using the [HyperDex Trainer](https://hugging-science-hyperdex-trainer.hf.space/) Space.

## Architecture

A standard `LlamaForCausalLM` decoder-only transformer — SiLU MLP, RMSNorm,
rotary position embeddings, grouped-query attention, tied embeddings, no biases —
scaled down in width and depth to fit the parameter budget.

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

tok = AutoTokenizer.from_pretrained("GGUFGuy/useless-parameters")
model = AutoModelForCausalLM.from_pretrained("GGUFGuy/useless-parameters")

ids = tok("The mitochondria is", return_tensors="pt").input_ids
print(tok.decode(model.generate(ids, max_new_tokens=60, do_sample=True,
                                temperature=0.8, top_k=50)[0]))
```

## Caveats

This is a **small-scale research artifact**. At this parameter count and token
budget the model learns word shapes, common collocations and a little syntax —
it is not a useful assistant and its output is not factual. It exists to make
"pre-train a transformer from scratch" something you can actually watch happen.
