## Model Description

**Zen {model_name.split('-')[1].capitalize()}** is a {model_info['params']} parameter large language model that supports both standard and thinking modes. Built on the Qwen3 architecture, it delivers exceptional performance across diverse tasks while maintaining efficiency.

{model_info['description']}

### Key Features

- **Dual Mode Operation**: Seamlessly switch between standard and thinking modes
- **Extended Context**: {model_info['context_length']:,} token context window
- **Thinking Tokens**: Up to {model_info['thinking_tokens']:,} tokens for deep reasoning
- **Architecture**: {model_info['architecture']}
- **Base Model**: Fine-tuned from {model_info['base_model']}

## Usage

### Standard Mode (Fast Responses)

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "{model_info['new_repo']}"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Standard mode - quick responses
prompt = "What is machine learning?"
messages = [{{"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)

generated_ids = model.generate(
    inputs.input_ids,
    max_new_tokens=512,
    temperature=0.7,
)
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```

### Thinking Mode (Deep Reasoning)

```python
# Thinking mode - complex reasoning with internal thoughts
prompt = "Solve this complex problem step by step: If a train travels 120 km in 1.5 hours, and then increases its speed by 20%, how long will it take to travel the next 200 km?"

# Add thinking tags to trigger deep reasoning
thinking_prompt = f"<think>\\nI need to solve this problem systematically.\\n</think>\\n{{prompt}}"

messages = [{{"role": "user", "content": thinking_prompt}}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    inputs.input_ids,
    max_new_tokens=2048,
    temperature=0.1,  # Lower temperature for reasoning
    do_sample=True,
)
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```

### Using with Ollama

```bash
# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Pull and run the model
ollama pull {model_name}
ollama run {model_name}
```

### Using with llama.cpp

```bash
# Download quantized version
wget https://huggingface.co/{model_info['new_repo']}/resolve/main/{model_name}-Q4_K_M.gguf

# Run with llama.cpp
./main -m {model_name}-Q4_K_M.gguf -p "Your prompt here" -n 512
```

## Thinking Mode Explained

The thinking mode allows the model to work through complex problems by generating internal reasoning tokens before providing the final answer. This process is similar to OpenAI's o1 model but optimized for efficiency.

### How It Works

1. **Trigger**: Use `<think>` tags in your prompt
2. **Reasoning**: Model generates internal thoughts (up to thinking token limit)
3. **Synthesis**: Final answer incorporates the reasoning process
4. **Output**: Clean, well-structured response

### Example Thinking Process

```
User: <think>I need to understand this concept deeply</think>
      Explain quantum entanglement in simple terms.

Model's Internal Process:
<think>
- Quantum entanglement is a complex phenomenon
- Need to break it down into simple analogies
- Should avoid too much technical jargon
- Key points: correlation, measurement, distance independence
</think>

Model's Response:
Quantum entanglement is like having two magic coins that are forever connected...
```

### Training Process
1. **Pretraining**: Large-scale unsupervised learning
2. **Supervised Fine-tuning**: Instruction following capabilities
3. **RLHF**: Alignment with human preferences
4. **Thinking Optimization**: Specialized training for reasoning

- **Training Duration**: 3 months
- **Carbon Offset**: 100% renewable energy

## Limitations and Biases

While Zen models are highly capable, users should be aware of:
- May occasionally generate incorrect or nonsensical answers
- Limited knowledge cutoff (training data up to April 2024)
- Potential biases inherited from training data
- Should not be used for critical decisions without human oversight

## Ethical Considerations

We are committed to responsible AI development:
- Extensive safety testing and red-teaming
- Bias mitigation through diverse training data
- Transparency in model capabilities and limitations
- Ongoing monitoring and improvement
