DALL-E API usage in Prompt Engineering / GenAI - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

intermediate

What is the output of this DALL-E API call?

Given the following Python code snippet using the DALL-E API, what will be the type of the variable response after execution?

Prompt Engineering / GenAI

import openai
response = openai.Image.create(
    prompt="a red apple on a wooden table",
    n=1,
    size="256x256"
)

A A string containing the raw image data

B A dictionary containing image URLs and metadata

C A list of image binary data

D An integer representing the number of images generated

💡 Hint

Think about what the API returns when you request images.

The DALL-E API returns a dictionary with keys like 'created' and 'data'. The 'data' key holds a list of dictionaries each containing a URL to the generated image.

❓ Model Choice

intermediate

Which DALL-E model size option produces the highest resolution images?

You want to generate the largest and most detailed images using the DALL-E API. Which size parameter should you choose?

A "256x256"

B "512x512"

C "128x128"

D "1024x1024"

💡 Hint

Higher numbers mean bigger images.

The '1024x1024' size option produces the highest resolution images currently supported by the DALL-E API.

❓ Hyperparameter

advanced

How does changing the n parameter affect the DALL-E API response?

If you set n=3 in the DALL-E API call, what will be the effect on the response?

A The API returns 3 images merged into one

B The API returns 1 image repeated 3 times

C The API returns 3 different images in the response

D The API returns 3 images but only one URL

💡 Hint

The parameter n controls how many images you want.

Setting n=3 tells the API to generate 3 unique images, each with its own URL in the response.

🔧 Debug

advanced

Why does this DALL-E API call raise an error?

Consider this code snippet: import openai response = openai.Image.create( prompt=12345, n=1, size="256x256" ) Why does this code raise an error?

A Because the prompt must be a string, not an integer

B Because the size parameter is invalid

C Because n must be greater than 1

D Because the openai module is not imported correctly

💡 Hint

Check the data type of the prompt parameter.

The prompt parameter must be a text string describing the image. Passing an integer causes a type error.

🧠 Conceptual

expert

What is the main ethical consideration when using DALL-E generated images?

When generating images with DALL-E, what is a key ethical concern to keep in mind?

A Ensuring images do not infringe on copyrights or create harmful content

B Avoiding the use of descriptive prompts

C Using the smallest image size to save bandwidth

D Maximizing the number of images generated per request

💡 Hint

Think about how images might affect others or violate rules.

Ethical use involves avoiding generating images that violate copyrights, promote misinformation, or create harmful or offensive content.
