# Image Generation Models

Text-to-image models are AI systems that create visual content directly from written descriptions or prompts. These models use advanced machine learning techniques to understand natural language and translate it into high-quality images, making them powerful tools for creative workflows.

{% hint style="warning" %}
**Deprecated:** **FLUX.1-schnell** will be removed from the AI Model Hub on **November 30, 2026**. Migrate to [<mark style="color:blue;">FLUX.2-klein-4B</mark>](/cloud/ai/ai-model-hub/models/image-generation-models/flux-2-klein-4b.md), its designated successor. FLUX.2-klein-4B is charged per megapixel of output plus input images instead of per image, so the cost per request changes when you switch.
{% endhint %}

* [<mark style="color:blue;">**FLUX.1-schnell**</mark>](/cloud/ai/ai-model-hub/models/image-generation-models/flux-1-schnell.md)**:** A German model by BlackForestLabs, optimized for fast and high-quality image generation from text prompts, suitable for creative, commercial, and educational applications.
* [<mark style="color:blue;">**FLUX.2-klein-4B**</mark>](/cloud/ai/ai-model-hub/models/image-generation-models/flux-2-klein-4b.md)**:** A compact 4B-parameter model by Black Forest Labs, designed for fast and resource-efficient text-to-image generation with strong visual fidelity.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ionos.com/cloud/ai/ai-model-hub/models/image-generation-models.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
