## Quick Start

### Python (Transformers)

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model_name = "my-ai-stack/Stack-X-Ultimate"

tokenizer = AutoTokenizer.from_pretrained(
    model_name,
    trust_remote_code=True
)

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto",
    trust_remote_code=True
)

# Generate response
prompt = "Explain the concept of sovereignty in AI systems and why it matters for enterprise deployment."

messages = [
    {"role": "system", "content": "You are Stack X Ultimate, a helpful and knowledgeable AI assistant."},
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

inputs = tokenizer([text], return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=512,
        temperature=0.7,
        top_p=0.95,
        do_sample=True,
    )

response = tokenizer.decode(
    outputs[0][inputs.input_ids.shape[1]:],
    skip_special_tokens=True
)

print(response)
```

### llama.cpp

```bash
# Download the GGUF model file

  -t 8 \
  -c 131072 \
  --temp 0.7 \
  --top-p 0.95 \
  -p "Write a Python function to implement quicksort algorithm."

# Run on CPU only
./main -m stack-x-ultimate-q4_k_m.gguf \
  -n 512 \
  -t 8 \
  -c 131072 \
  --no-display \
  --threads 8 \
  -p "Explain the differences between sovereign AI and cloud-based AI solutions."

# Use with quantization comparison
