|
|
| ## π οΈ Core Features |
|
|
| ### Reasoning Channels |
|
|
| The model operates across multiple channels for structured thinking: |
|
|
| ``` |
| analysis β Internal reasoning and tool usage (Python, browser) |
| commentary β Function calls and external tool integration |
| final β 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 β Quick, intuitive responses |
| medium β Balanced thinking (default) |
| high β Deep, thorough analysis |
| ``` |
|

| - Full control over tool usage |
| - Inspect code before execution |
| |
| **Browser Tool Considerations:** |
| - Browser tools do make external web requests |
| - Review URLs and search queries before execution |
| - Content fetched is processed locally |
| |
| **Python Execution Safety:** |
| - Sandboxed environment with 120s timeout |
| - File access limited to `/mnt/data` |
| - No network access from Python by default |
| - Review generated code before running |
| |
| ## π¦ Best Practices |
| |
| ### Effective Prompting |
| ``` |
| β Vague: "Tell me about AI" |
| β
Specific: "Search for recent breakthroughs in transformer architecture |
| from 2024, then summarize the top 3 findings" |
| |
| β Too broad: "Analyze my data" |
| β
Actionable: "Load sales.csv, calculate monthly revenue trends, |
| and create a line plot showing growth over time" |
| ``` |
| |
| ### Tool Usage |
| - **Search first** - Use browser before asking knowledge questions |
| - **Verify with code** - Use Python to validate calculations |
| - **Cite sources** - Pay attention to citation numbers |
| - **Check dates** - Knowledge cutoff is June 2024 |
| |
| ### Reasoning Control |
| ```bash |
| # Quick responses |
| ollama run Raiff1982/gpt-oss --reasoning low "Quick question..." |
| |
| # Deep analysis |
| ollama run Raiff1982/gpt-oss --reasoning high "Complex problem..." |
| ``` |
