• Common Aspect Ratios: Supports 1:1, 3:4, 4:3, 9:16, and 16:9.
• Person Generation Control: Use personGeneration (dont_allow, allow_adult, allow_all) to govern depiction of people.
• Asynchronous Architecture: Uses a ““Create Task → Poll Result”” API workflow for reliable integration.

How to Use Imagen 4.0

1. Write a specific, detailed text prompt describing the scene, subject, and style.
2. Submit a POST request to the /google/imagen-4.0-generate-001 endpoint with your prompt and optional sampleCount, aspectRatio, personGeneration, and imageSize.
3. Receive a task_id with a ““pending”” status in the response.
4. Poll the provided GET endpoint to monitor the task.
5. Once complete, retrieve and download the generated image(s).

Best Use Cases
