# Image Generation Nodes

This section introduces the core nodes used for **Text → Image** generation and **Image → Text** extraction.

### **Text → Image** (Fast) <a href="#fast-text-to-image" id="fast-text-to-image"></a>

The **Text → Image (Fast)** node generates images quickly based on a text prompt.\
It uses a lightweight backend optimized for **speed** rather than fidelity.

This node is ideal when you need:

* rapid ideation
* quick thumbnails
* early explorations of a concept
* instant variations&#x20;

The output is less detailed and less accurate compared to the **High Quality** version of the node, but significantly faster.

### Text **→** Image (High Quality) Node <a href="#quality-text-to-image" id="quality-text-to-image"></a>

The **Text → Image (High Quality)** node produces **high-fidelity, detailed images**.\
It uses **different backends**, allowing you to choose based on rendering styles and strengths.

#### Key Features <a href="#key-features" id="key-features"></a>

* best visual quality among text-only generation nodes
* multiple backends → diverse interpretations
* good for environments, props, characters, concept art
* consistent structure and lighting compared to faster models

#### Example: Fast v. High Quality <a href="#example-quality-vs-fast" id="example-quality-vs-fast"></a>

Both nodes receive the same prompt.

The Fast node generates a quick idea; the High Quality node generates a polished version suitable for downstream workflows such as:

* Image → 3D
* Text + Image → Image
* Edit Image with Text
* Marketing assets

### Describe Image Node & Describe Images Node <a href="#image-to-text" id="image-to-text"></a>

The **Describe Image** node converts an image into structured or descriptive text.

The **Describe Images** node converts multiple images into structured or descriptive text.\
The system prompt controls what type of information is extracted.

These nodes can be powerful ways to craft custom, detailed prompts for image generation.

#### You can request: <a href="#you-can-request" id="you-can-request"></a>

* scene description
* object list
* spatial layout
* material analysis
* asset identification
* style breakdown
* inferred function or purpose

#### Example Use Cases <a href="#example-use-cases" id="example-use-cases"></a>

* Describe the objects in a rendered scene
* Extract the composition of a top-down plan
* Identify modular parts of a building
* Produce a clean text prompt for concept art
* Provide metadata for Make3D or Auto Mesh Transform
