What Imagen 4 does

Imagen 4 is Google's text-to-image model for realistic photos and clean compositions. Set number_of_images (1 to 4), image_size (1K or 2K), aspect_ratio (1:1, 3:4, 4:3, 9:16 or 16:9) and person_generation (dont_allow or allow_adult). Every image carries Google's SynthID watermark. Imagen 4 Fast and Imagen 4 Ultra take the same inputs.

Call Imagen 4 from code

The same model, from an agent or from your own code. Keys stay in your FlyMy.AI account.

From an agent, through the MCP

The agent calls get_model_schema, then run_model with:

{
  "endpoint_id": "flymyai/imagen-4",
  "input": {
    "prompt": "A ceramic mug on a sunlit kitchen counter, product photo"
  }
}

From your code, over HTTP
