+1. **Session management**:
+   - **Session ID**: Use unique identifiers for different conversations (e.g., "project1", "analysis2")
+   - **Session Memory**: Toggle on/off to maintain conversation context across multiple runs
+   - **Clear Session**: Reset conversation memory when starting new topics
+
+2. **Model selection**:
+   - **seed-1-6-250615**: Balanced performance and quality
+   - **seed-1-6-flash-250715**: Faster responses, optimized for speed
+
+3. **Configure thinking and reasoning**:
+   - **Thinking mode**: Enable for deeper reasoning (default: enabled)
+   - **Reasoning effort**: Adjust computational intensity (low/medium/high)
+
+4. **Use multimodal features**:
+   - Attach up to 4 images simultaneously
+   - Set image detail level (auto/high/low) based on your needs
+   - High detail for analysis, low detail for simple recognition
+
+5. **Conversation continuity**:
+   - **Built-in memory**: Automatically remembers previous messages in the session
+   - **External history**: Import conversations from other sources
+   - **Full conversation output**: Get formatted conversation history for export/review
