# This sample shows how to create a chatbot that responds to user messages with image input.
# This sample uses the following three main components:
# - a ChatCompletionService: This component is responsible for generating responses to user messages.
# - a ChatHistory: This component is responsible for keeping track of the chat history.
# - an ImageContent: This component is responsible for representing image content.
# The chatbot in this sample is called Mosscap.

# You can select from the following chat completion services:
# - Services.OPENAI
# - Services.AZURE_OPENAI
# - Services.AZURE_AI_INFERENCE
# - Services.ANTHROPIC
# - Services.BEDROCK
# - Services.GOOGLE_AI
# - Services.MISTRAL_AI
# - Services.OLLAMA
# - Services.ONNX
# - Services.VERTEX_AI
# Please make sure you have configured your environment correctly for the selected chat completion service.

# [NOTE]
# Not all models support image input. Make sure to select a model that supports image input.
# Not all services support image input from an image URI. If your image is saved in a remote location,
# make sure to use a service that supports image input from a URI.

    # Sample output:
    # Mosscap:> The image features a large, historic building that exhibits a traditional half-timbered architectural
    #           style. The structure is located near a dense forest, characterized by lush green trees. The sky above
    #           is partly cloudy, suggesting a pleasant day. The building itself appears well-maintained, with distinct
    #           features such as a turret or spire and decorative wood framing, creating an elegant and charming
    #           appearance in its natural setting.
    # User:> What do you think about the composition of the photo?
    # Mosscap:> The composition of the photo is quite effective. Here are a few observations:
    #           1. **Framing**: The building is positioned slightly off-center, which can create a more dynamic and
    #           engaging image. This drawing of attention to the structure, while still showcasing the surrounding
    #           landscape.
    #           2. **Foreground and Background**: The green foliage and trees in the foreground provide a nice contrast
    #           to the building, enhancing its visual appeal. The dense forest in the background adds depth and context
    #           to the scene.
    #           3. **Lighting**: The light appears to be favorable, suggesting a well-lit scene. The clouds add texture
    #           to the sky without overwhelming the overall brightness.
    #           4. **Perspective**: The angle from which the photo is taken allows viewers to appreciate both the
    #           architecture of the building and its natural environment, creating a harmonious balance.
    #           Overall, the composition successfully highlights the building while incorporating its natural
    #           surroundings, inviting viewers to appreciate both elements together.
