## 🚀 Usage Guide

### Quick Start

```python
from transformers import pipeline

# Initialize the pipeline with the model
pipe = pipeline("text-generation", 
                model="Daemontatox/Manticore-32B",
                torch_dtype="auto")

# Basic chat format
messages = [
    {"role": "user", "content": "Can you solve this math problem step by step? If a rectangle has a perimeter of 30 meters and a length that is twice its width, what are the dimensions of the rectangle?"}
]

# Generate response
response = pipe(messages, 
                max_new_tokens=512, 
                do_sample=True, 
                temperature=0.7,
                top_p=0.95)

print(response[0]["generated_text"])
```

### Advanced Usage

For more control over generation parameters and to utilize advanced features:

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

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("Daemontatox/Manticore-32B")
model = AutoModelForCausalLM.from_pretrained(
    "Daemontatox/Manticore-32B",
    torch_dtype=torch.bfloat16,
    device_map="auto",
    load_in_4bit=True
)

# Format messages in chat template
messages = [
    {"role": "system", "content": "You are Manticore-32B, an AI assistant specialized in reasoning and problem-solving. Always show your work step-by-step when tackling problems."},
    {"role": "user", "content": "Write a recursive function in Python to calculate the nth Fibonacci number with memoization."}
]

# Create prompt using chat template
prompt = tokenizer.apply_chat_template(messages, tokenize=False)

# Generate with more control
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    inputs.input_ids,
    max_new_tokens=1024,
    do_sample=True,
    temperature=0.7,
    top_p=0.95,
    top_k=40,
    repetition_penalty=1.1
)

# Decode and print result
response = tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True)
print(response)
```

#### Using with Unsloth for Even Faster Inference

```python
from unsloth import FastLanguageModel
import torch

# Load with Unsloth for optimized inference
model, tokenizer = FastLanguageModel.from_pretrained(
    "Daemontatox/Manticore-32B",
    dtype=torch.bfloat16,
    load_in_4bit=True,
    token="your_huggingface_token"  # Optional
)

# Create prompt
messages = [
    {"role": "user", "content": "Explain the concept of computational complexity and give examples of O(1), O(n), and O(n²) algorithms."}
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False)

# Generate
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    inputs.input_ids,
    max_new_tokens=768,
    temperature=0.7
)

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

## 📈 Benchmarks

Manticore-32B demonstrates strong performance across multiple reasoning benchmarks:

| Benchmark | Score | Base Model Score | Improvement |
|-----------|-------|------------------|-------------|
| GSM8K     | 78.2% | 71.5%            | +6.7%       |
| MATH      | 42.5% | 37.8%            | +4.7%       |
| HumanEval | 75.6% | 71.3%            | +4.3%       |
| BBH       | 69.3% | 64.8%            | +4.5%       |

*Note: These benchmarks reflect zero-shot performance with temperature=0.0*

## ⚠️ Limitations

Despite its strengths, users should be aware of the following limitations:

- **Language Support**: Primarily optimized for English; performance degrades significantly for other languages
- **Factual Accuracy**: While reasoning skills are enhanced, the model may still hallucinate factual information
- **Domain Knowledge**: Specialized knowledge outside common domains may be limited or incorrect
- **Context Window**: Default context window is inherited from Qwen3-32B (128K tokens)
- **Bias**: Inherits potential biases from base model and synthetic training data
