### Choosing a version

Our AI versions work like **release channels** rather than fixed version numbers — you point your requests at a channel and we keep it updated to the right underlying release as the AI improves over time. Pick the channel that suits you:

* `latest` — our newest public release, updated as soon as new versions ship. This is the default if you don't specify a version.
* `stable` — a `latest` release that has been proven reliable across hundreds of thousands of images before being promoted. Best for consistent, predictable behaviour at scale.
* `beta` — our experimental channel, with early access to flagship features still in development.

Select a channel in the Webapp, or send it as a string (`latest`, `stable`, or `beta`) in your API request. The channels currently point to these releases:

| Channel  | Current release |
| -------- | --------------- |
| `latest` | 5.3.9           |
| `stable` | 5.3.9           |
| `beta`   | 5.4.1           |

<details>

<summary>For existing customers — migrating from numbered versions</summary>

We've simplified how we name and release AI versions. Previously you pinned to a fixed version number; now you subscribe to one of the rolling channels above, and we keep each pointed at the right release.

**Your existing integration keeps working** — older numbered versions are upgraded automatically:

* Any version above `4.7` (the old numbered `5.0`–`5.3` releases) is automatically upgraded to `stable`.
* Any version below `4.7` is automatically upgraded to `4.7`.
* `4.7` itself remains available to selected legacy customers — see [Legacy AI Versions](#legacy-ai-versions) below.

# 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 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://docs.autoenhance.ai/ai-version.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.
