  -d '{"model": "imagen-4", "prompt": "..."}'

## Positioning

Imagen 4 is Google’s standard text-to-image model, optimized for photorealistic portraits, branded scenes, and hero images. Reach for it when you need a balanced cost-to-quality ratio for general image generation workflows.

## About

Imagen 4 is a text-to-image model from Google that produces photorealistic humans, sharp embedded text, and richly composed scenes. It operates as the default quality tier, accepting text prompts and returning image outputs.

On Kyma, the model runs through an OpenAI-compatible endpoint with automatic failover across serving paths. Every request reports exact cost in usage.cost and the active model via the X-Kyma-Model header. Prompt caching is enabled, billing repeated prompt prefixes at 10% of the standard input rate.

The model does not support reasoning, vision input, or structured outputs. It generates images on a per-image basis at a medium speed tier and is positioned at a balanced cost tier.

## Use cases

- **Photorealistic Portrait Generation** — Generate lifelike human portraits with accurate lighting and skin tones.
- **Branded Marketing Visuals** — Produce campaign-ready images with sharp, legible embedded text.
- **Website Hero Imagery** — Create richly composed header graphics for landing pages.
- **Product Scene Mockups** — Render realistic product placements in controlled environments.

## Not ideal for

Do not use this model for tasks requiring image-to-image editing, structured JSON outputs, or sub-second generation latency.

## Pick something else when

- You need faster generation latency → `imagen-4-fast`
- You require maximum photorealism and detail → `imagen-4-ultra`
- You need scalable vector graphics → `recraft-v4-vector`
