### A Quick 2.0 Recap

[Version 2.0](/versions/2.0) was a major redesign focused on **simplicity**, **privacy**, and **autonomy**, introducing:

* **BYOK models** (Anthropic)
* **Custom MCP servers** (remote or local)
* **One-click agents**
* **Recurring automations**
* **Context without copy/paste**
* And much more…

Version 2.1 builds directly on that foundation.

***

### Open Source

AI Thing is now fully **open source**. Browse, audit, or contribute to the codebase: **[https://github.com/aithing-lab/aithing-mac](https://github.com/aithing-lab/aithing-mac)**

Open sourcing is a continuation of our commitment to privacy, transparency, and user ownership.

***

### Support for OpenAI and Gemini [BYOK Models](/features/byok-models)

Version 2.1 adds first-class support for:

* **OpenAI GPT-5 series**
* **Google Gemini 3 and 2.5 series**
* Existing **Claude 4.5** models
* Plus any additional models you want to bring yourself

Choose the model that fits the task — and **use multiple models within a single conversation**.

***

### Notifications for [Automations](/features/automations)

Automations now send **native macOS notifications** when tasks start, run, or complete in the background.

No more checking or reopening a window — you’ll know exactly when something’s done.
