💡 Hint

Common Mistakes

Using incorrect class names like 'DALL-E' or 'DalleApi'.

Trying to import a module instead of the client class.

The correct import for the OpenAI client is 'OpenAI' from the OpenAI library.

Complete the code to create an OpenAI client instance using the API key stored in the environment variable.

Prompt Engineering / GenAI

client = OpenAI(api_key=[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong environment variable name.

Using os.environ which throws error if variable is missing.

The API key is usually stored in the environment variable 'OPENAI_API_KEY' and accessed with os.getenv for safety.

Fix the error in the code to generate an image with DALL-E using a prompt string.

Prompt Engineering / GenAI

response = client.images.generate(model="dall-e-2", prompt=[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Passing the prompt without quotes causing a NameError.

Passing a list or dictionary instead of a string.

The prompt must be a string literal, so it needs quotes around it.

Fill both blanks to set the image size and number of images to generate.

Prompt Engineering / GenAI

response = client.images.generate(model="dall-e-2", prompt='A cat playing piano', size=[1], n=[2])

Drag options to blanks, or click blank then click option'

A'1024x1024'

B'512x512'

💡 Hint

Common Mistakes

Using integers for size instead of string.

Setting n to a string instead of an integer.

The size should be a string like '512x512' and n is the number of images, here 3.

5fill in blank

hard

Fill all three blanks to extract the image URL from the response dictionary.

Prompt Engineering / GenAI

image_url = response.[1][[2]].[3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong keys like 'images' instead of 'data'.

Using string '0' instead of integer 0 for index.

Trying to access 'url' directly from response.

The response contains a 'data' list, we take the first item [0], then get its 'url' field.
