## 🚀 Quick Start

```bash
# Pull and run the model
ollama pull Raiff1982/gpt-oss
ollama run Raiff1982/gpt-oss
```

## 🎯 What Makes This Model Special?

GPT-OSS provides a feature-complete ChatGPT experience with:

- **🧠 Multi-Level Reasoning** - Built-in analysis channels for deep thinking
- **🌐 Browser Integration** - Search, open, and find information on the web
- **🐍 Python Execution** - Run Python code in a stateful Jupyter environment
- **🔧 Tool Calling** - Extensible function calling framework
- **📊 Data Persistence** - Save and load files to `/mnt/data`
- **💭 Chain of Thought** - Transparent reasoning with configurable depth

## 🛠️ Core Features

### Reasoning Channels

The model operates across multiple channels for structured thinking:

```
analysis     → Internal reasoning and tool usage (Python, browser)
commentary   → Function calls and external tool integration
final        → User-facing responses and conclusions
```

This architecture enables:
- **Transparent reasoning** - See how the model thinks
- **Tool integration** - Seamlessly use Python/browser without breaking flow
- **Clean output** - Separate internal work from final answers

### Browser Tools

Built-in web browsing capabilities:

```python
# Search the web
browser.search(query="latest AI research", topn=10)

# Open specific results
browser.open(id=3, loc=0, num_lines=50)

# Find text on page
browser.find(pattern="neural networks")
```

**Use cases:**
- Research current events and news
- Find technical documentation
- Verify facts and statistics
- Compare information across sources

### Python Code Execution

Stateful Jupyter notebook environment:

```python
# Execute code directly
import pandas as pd
import matplotlib.pyplot as plt

# Load and analyze data
df = pd.read_csv('/mnt/data/data.csv')
df.describe()

# Create visualizations
plt.plot(df['x'], df['y'])
plt.savefig('/mnt/data/plot.png')
```

**Capabilities:**
- Full Python standard library
- Data analysis (pandas, numpy)
- Visualization (matplotlib, seaborn)
- Machine learning (scikit-learn)
- File persistence in `/mnt/data`
- 120 second execution timeout

### Reasoning Levels

Control analysis depth with reasoning parameters:

```
low     → Quick, intuitive responses
medium  → Balanced thinking (default)
high    → Deep, thorough analysis
```

✅ Specific: "Search for recent breakthroughs in transformer architecture 
              from 2024, then summarize the top 3 findings"

❌ Too broad: "Analyze my data"
✅ Actionable: "Load sales.csv, calculate monthly revenue trends, 
                and create a line plot showing growth over time"
```

### Tool Usage
