            **For Current Events:**
            - Use tool-based models (openai/gpt-oss-20b)
            - Set search type to "browser_search"
            - Enable "Force Search" for real-time data
            
            **For Creative Tasks:**
            - Any model works well
            - Set search type to "none" for purely creative responses
            - Use higher temperature (0.8-1.0) for more creativity
