```

## Positioning

Imagen 4 Fast is Google’s quickest image generation tier, optimized for rapid iteration and lower-fidelity outputs. Reach for it when you need fast drafts, social media previews, or high-volume generation where speed matters more than maximum detail.

## About

Imagen 4 Fast is a text-to-image model from Google that generates photorealistic and multi-style visuals. It operates in a fast, cheap tier that prioritizes generation speed over maximum fidelity.

On Kyma, it accepts text prompts and returns images. It supports prompt caching, and requests are routed through an OpenAI-compatible endpoint with automatic failover if a serving path degrades. Usage responses include exact costs in usage.cost and report the running model via the X-Kyma-Model header.

This model does not support vision input, structured outputs, or reasoning. Token limits do not apply to this text-to-image workflow. Use it for quick visual drafts rather than final production assets requiring high detail.

## Use cases

- **Rapid Concept Drafting** — Quickly generate placeholder visuals during early design phases.
- **Social Media Previews** — Produce fast, multi-style images for content scheduling and testing.
- **High-Volume Generation** — Scale image creation workflows where speed and cost efficiency matter more than maximum detail.

## Not ideal for

Do not use this tier for final production assets or workflows that require high-fidelity detail, vision input, or structured output parsing.

## Pick something else when

- You need maximum image fidelity and detail → `imagen-4-ultra`
- You require vector graphics or design-ready assets → `recraft-v4-vector`
- You need high-quality photorealism with advanced prompt control → `flux-2-pro`
