# Starlight Precise 2.6

High-quality upscaling and enhancement for GenAI and archival video with realistic faces, textures, text clarity, and temporal consistency

### Model Overview

**Starlight Precise 2.6** is a diffusion video enhancement model designed to upscale footage up to 4K while improving realism and detail across both AI-generated and archival video. Building on Precise 2.5, it enhances faces, fabrics, materials, and textures while improving the clarity of text, labels, logos, and other fine details.

Starlight Precise 2.6 delivers up to 15% faster rendering across both cloud and local processing, with improved temporal consistency that reduces periodic flickering and produces more stable results across longer sequences and multiple clips. A new Sharpen parameter gives the ability to dial back over-sharp details for a smoother, softer look.

### Key Capabilities

* Upscales and enhances GenAI and archival video up to 4K.
* Improved faces, materials, textures, text, labels, and fine detail.
* Up to 15% faster rendering across both cloud and local processing.
* Improved temporal consistency reduces flickering and provides greater stability across longer sequences and multiple clips.
* New Sharpen parameter controls the balance between softer, natural look and sharper generative enhancement.

## 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/starlight/starlight-precise-2.6.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.
