# Astra 1 (Deprecated)

### Model Overview

**Astra** **1** is a creative diffusion-based upscaling model designed specifically for GenAI video. It transforms AI-generated footage to 4K by adding new, dynamic detail and texture, producing expressive and stylized results beyond traditional enhancement.

Astra 1 allows creators to control the level of creative transformation, from subtle refinement to bold, highly stylized output. It enhances clarity, richness, and visual complexity by adding new detail and texture to GenAI video. Due to its scale and creative flexibility, Astra 1 is a cloud-only model optimized for high-capacity processing.

### Key Capabilities

* Creative diffusion-based upscaling for GenAI video at 4K
* Adds new detail and texture with adjustable creative intensity

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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.topazlabs.com/video-models/astra/astra-1-deprecated.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
