### π¬ Chat Mode Features
**Conversation Memory:**
- AI remembers previous messages
- Can reference earlier topics
- Natural multi-turn dialogue
**How It Works:**
1. **Orchestrator**: Breaks your query into questions (with context)
2. **Agents**: Analyze in parallel (aware of conversation)
3. **Synthesizer**: Creates contextual response
### Tips
- Ask follow-up questions
- Request clarifications
- Build on previous answers
- Clear chat to start fresh
### Model Recommendations
- **Claude 4.5**: Best reasoning
- **GPT-5**: Creative responses
- **GPT-5.1**: Frontier reasoning + creativity
- **Gemini 3 Pro Preview**: Multimodal depth
- **Gemini 2.5 Pro**: Great synthesis
- **Enable web search** for current info!
