When starting a new chat, choosing the appropriate AI language model ensures you receive the best responses based on your needs. ChatNGO offers several models, each with its own strengths.&#x20;

### **Steps to Select a Language Model:**

1. **Click on the Model Dropdown**:
   * Below the chat bar, you will see a dropdown that shows the currently selected model (e.g., GPT-4o, GPT-4o Mini, Claude 3.5 Sonnet).
   * Click on this dropdown to view the available models.
2. **Review Model Options**:
   * The models available for selection include:
     * **GPT-4o**: Ideal for handling detailed and complex tasks with greater depth and reasoning.
     * **GPT-4o Mini**: A lighter, faster version of GPT-4o, suitable for simpler tasks or when quicker responses are needed.
     * **Claude 3.5 Sonnet**: Best for natural language understanding and creative tasks; known for its conversational fluency.
3. **Choose Your Model**:
   * Select the model that best fits your needs by clicking on it from the dropdown list.
   * The selected model will be active for the current chat session and all future interactions within that thread.
