## Quick Start

```python
from transformers import GPT2LMHeadModel, GPT2TokenizerFast
import torch

model_id  = "GODsStrongestSoldier/GPT2.5.5-Awakened.Thinker-0.1B"
tokenizer = GPT2TokenizerFast.from_pretrained(model_id)
model     = GPT2LMHeadModel.from_pretrained(model_id, torch_dtype=torch.float16)
model.eval()

prompt = "Let me think through this carefully, step by step:"
inputs = tokenizer(prompt, return_tensors="pt")

with torch.no_grad():
    output = model.generate(
        **inputs,
        max_new_tokens     = 200,
        do_sample          = True,
        temperature        = 0.7,
        top_p              = 0.9,
        repetition_penalty = 1.15,
    )

print(tokenizer.decode(output[0], skip_special_tokens=True))
```
