Generative AI Leader Fundamentals of Generative AI Practice Question
A company wants to generate images from text descriptions using Google Cloud. Which service should they use?
⚠ Common exam trap
A common mix-up: candidates confuse Vertex AI Gemini's multimodal capabilities (understanding images) with generative image creation, or assume that Cloud Vision API or AutoML Vision can be repurposed for generation, when in fact they are strictly analysis or custom training tools.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Vertex AI Imagen
Vertex AI Imagen is Google Cloud's purpose-built service for generating high-fidelity images from text descriptions using diffusion models. It directly addresses the requirement of text-to-image generation, offering capabilities like image editing, upscaling, and style transfer, which are not available in other Vertex AI or Vision services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Vertex AI Imagen
Why this is correct
Vertex AI Imagen generates images directly from text prompts, satisfying the stem's requirement for text-to-image generation on Google Cloud. Unlike Vertex AI's language or vision models, Imagen is purpose-built for photorealistic image synthesis, offering resolution, editing and watermark controls that match this scenario precisely.
- ✗
Vertex AI Gemini
Why it's wrong here
Gemini on Vertex AI handles multimodal understanding and text generation, but text-to-image synthesis requires Imagen, which is the dedicated model for that task. Gemini is tempting because it is Vertex AI's flagship generative offering, and it would be correct for multimodal reasoning over existing images rather than creating them.
- ✗
Cloud Vision API
Why it's wrong here
Cloud Vision API performs analysis on supplied images, such as labelling, OCR and face detection; it cannot synthesise new images from a text prompt. It is tempting because it is Google Cloud's best-known vision service, and it would be the right pick for classifying or extracting text from existing pictures.
- ✗
AutoML Vision
Why it's wrong here
AutoML Vision trains custom classification or object-detection models on your labelled image dataset; it does not generate images from prompts. It is tempting because it is a managed vision service, and it would be correct when you need a bespoke image classifier for your own categories.
