### Description:
|
326 |
+
This is a multimodal chatbot that can handle text, image, voice, and PDF inputs.
|
327 |
+
- You can ask questions or provide text, and the assistant will respond.
|
328 |
+
- You can upload an image, and the assistant will process it and answer questions about the image.
|
329 |
+
- Voice input is supported: You can upload or record an audio file, and it will be transcribed to text and sent to the assistant.
|
330 |
+
- PDF support: Upload a PDF and ask questions about its content.
|
331 |
+
- Enter your OpenAI API key to start interacting with the model.
|
332 |
+
- You can use the 'Clear History' button to remove the conversation history.
|
333 |
+
- "o1" is for image, voice, PDF and text chat and "o3-mini" is for text, PDF and voice chat only.
|
334 |
+
### Reasoning Effort:
|
335 |
+
The reasoning effort controls how complex or detailed the assistant's answers should be.
|
336 |
+
- **Low**: Provides quick, concise answers with minimal reasoning or details.
|
337 |
+
- **Medium**: Offers a balanced response with a reasonable level of detail and thought.
|
338 |
+
- **High**: Produces more detailed, analytical, or thoughtful responses, requiring deeper reasoning.
