## 💻 Quick Start

### Installation
```bash
pip install transformers torch accelerate
```

### Basic Usage (Text Generation)
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "QuantaSparkLabs/Antiplex-instruct-3B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.float16,
    device_map="auto"
)

prompt = "Write an SQL query to fetch users created in the last 30 days."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=256,
    temperature=0.7,
    top_p=0.9,
    do_sample=True,
    pad_token_id=tokenizer.eos_token_id
)

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

### Classification Mode
```python
# Intent classification example
classification_prompt = """[CLASSIFY]
User Query: "I need to reset my account password"
Categories: account_issue, technical_support, billing, general_inquiry
"""

inputs = tokenizer(classification_prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=64,
    temperature=0.3,
    do_sample=False
)

detected_intent = tokenizer.decode(outputs[0], skip_special_tokens=True).split('[')[-1].split(']')[0]
print(f"Detected Intent: {detected_intent}")
```

### Chat Interface
```python
from transformers import pipeline

chatbot = pipeline(
    "text-generation",
    model=model_id,
    tokenizer=tokenizer,
    device=0 if torch.cuda.is_available() else -1
)

messages = [
    {"role": "system", "content": "You are Antiplex, a helpful AI assistant specialized in SQL and classification tasks."},
    {"role": "user", "content": "Classify this intent: 'Can you help me with invoice generation?' Then write a SQL query to find recent invoices."}
]

response = chatbot(messages, max_new_tokens=512, temperature=0.7)
print(response[0]['generated_text'][-1]['content'])
```

## ⚠️ Limitations & Safety

### Known Limitations
- **Domain Specificity**: Not trained for medical/legal/safety-critical domains
- **Bias Inheritance**: May reflect biases in training data
- **Context Window**: Limited to 4K tokens
- **Multilingual**: Primarily English-focused

### Safety Guidelines
```python
# Recommended safety wrapper
def safety_check(text):
    blocked_terms = ["harmful", "dangerous", "illegal", "exploit"]
    if any(term in text.lower() for term in blocked_terms):
        return "Content filtered for safety reasons."
    return text
```
