Hi @anu43, are you running the sample out of the box, without modifications? Please let me know what OpenAI model you're using. I am able to run it with gpt-4o, as an example.

# AuthorRole.USER: 'Describe this image.'
# AuthorRole.ASSISTANT: The image depicts the bustling atmosphere of Times Square in New York City. It's a vibrant scene filled with bright lights and large digital billboards advertising various brands and shows. The scene is crowded with people walking and taking photos, and there are numerous taxis and vehicles on the streets. Visible logos and advertisements include well-known brands such as McDonald's, Samsung, and various Broadway shows. The architecture is tall and modern, with a towering skyline. Signs and billboards contribute to the lively, energetic feel characteristic of Times Square, a major commercial and tourist hub.
# AuthorRole.USER: 'What is the main color in this image?'
# AuthorRole.ASSISTANT: The main color in this image is blue. This is evident from the vast expanse of water surrounding the great white shark and the school of fish. The shades of blue range from light to dark, dominating the image and contributing to the underwater environment's overall appearance.
# AuthorRole.USER: 'Is there an animal in this image?'
# AuthorRole.ASSISTANT: Yes, there is an animal in this image. It features a cat sitting gracefully in a lush, colorful garden. The garden is filled with a variety of flowers and greenery, creating a serene and picturesque setting.

I ran this by Azure OpenAI's gpt-4o 2024-02-15-preview. What Azure OpenAI model would you suggest?
