    ## Instructions
    - Type a question or statement
    - Upload images or audio files
    - You can combine text with media files
    - Support 2 modalities at the same time
    - The model can analyze images and transcribe audio
    - For best results with images, use JPG or PNG files
    - For audio, use WAV, MP3, or FLAC files

    ## Capabilities
    This chatbot can:
    - Answer questions and provide explanations
    - Describe and analyze images
    - Transcribe, translate, summarize, and analyze audio content
    - Process multiple inputs in the same message
    - Maintain context throughout the conversation
