# Quantum-X
A compact, high‑speed conversational AI built on **Qwen 2.5 0.5B** — small enough for edge devices, smart enough for real conversation.
## 📋 Overview
Quantum‑X is a **0.5 billion parameter** language model developed by QuantaSparkLabs. It's fine‑tuned from Qwen 2.5 0.5B on a mix of OpenHermes‑2.5 conversations and custom identity data, giving it warm, direct conversational abilities while keeping inference blazingly fast.
| Feature | Detail |
|---------|--------|
| **Base Model** | Qwen 2.5 0.5B‑Instruct |
| **Parameters** | ~0.5B |
| **Fine‑tuning** | QLoRA (Unsloth), 2 epochs |
| **Training Data** | OpenHermes‑2.5 + identity examples |
| **Tensor Precision** | FP16 |
| **Chat Template** | ✅ Native Qwen2 chat template |
## ✨ What It Does Well
- **Conversational AI**: Natural, warm dialogue with identity baked in.
- **Factual Q&A**: Answers general knowledge questions correctly.
- **Fast Inference**: 0.5B parameters = near‑instant responses on CPU or GPU.
- **Edge Friendly**: Runs comfortably on 2 GB RAM, even on a phone.
## 💻 Quick Start
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
model_id = "QuantaSparkLabs/Quantum-X"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.float16,
device_map="auto",
trust_remote_code=True
)
messages = [
{"role": "system", "content": "You are Quantum-X, created by QuantaSparkLabs."},
{"role": "user", "content": "What is the capital of France?"}
]
inputs = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
input_ids = tokenizer(inputs, return_tensors="pt").to(model.device)
outputs = model.generate(**input_ids, max_new_tokens=100, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
## 🚀 Hardware Requirements
| Environment | RAM | Storage | Ideal For |
| :--- | :--- | :--- | :--- |
| **CPU** | 2 GB | ~500 MB | Testing, embedded apps |
| **GPU** | 1‑2 GB VRAM | ~500 MB | Development, serving |
| **Edge / Mobile** | >1 GB | ~500 MB | On‑device inference |
## ⚠️ Limitations
- **Complex reasoning**: Multi‑step logic or advanced math may be inconsistent.
- **Factual precision**: Can occasionally produce outdated or incorrect information.
- **Not for high‑stakes use**: Don't use for medical, legal, or safety‑critical decisions.
