Delegate text generation to another AI model. Use this when you need capabilities
or perspectives from a different model than yourself.

Args:
    provider: The AI provider to use (e.g., "openai", "anthropic", "google", "groq")
    model: The specific model identifier (e.g., "gpt-4o", "claude-3-5-sonnet-20241022", "gemini-2.0-flash-exp")
    prompt: The instruction or query to send to the external model

Returns:
    The text response from the external model, or an error message if the request fails

Example usage:
    To get a different perspective: provider="anthropic", model="claude-3-5-sonnet-20241022", prompt="Analyze this problem from a different angle..."
    To leverage specialized models: provider="deepseek", model="deepseek-coder", prompt="Write optimized Python code for..."

Delegate image generation to an external AI model. Use this when you need to create
visual content.

Args:
    provider: The AI provider to use (currently only "openai" is supported)
    model: The image model to use ("dall-e-3" for high quality, "dall-e-2" for faster/cheaper)
    prompt: A detailed description of the image you want to generate

Returns:
    The URL of the generated image, which can be shared with users or used in responses

Example usage:
    For high-quality images: provider="openai", model="dall-e-3", prompt="A photorealistic rendering of..."
    For quick concepts: provider="openai", model="dall-e-2", prompt="A simple sketch showing..."

Note: Only OpenAI currently supports image generation. Other providers will return an error.
