Modelbase Support

Modelbase is a free chat app for iPhone, iPad and Mac that runs open AI models on your own device, with Apple's MLX. It works without internet, needs no account, and keeps your chats on your device.

Yes. Modelbase is free to download and use, with no account. If a later version offers paid features, they will be sold through Apple, and you will see the price before you buy.

Yes. A chat with a model on your device needs no connection, so it works in airplane mode. Web search, live cards, and models from OpenRouter or your own server need one.

Yes, with a model that runs on the device. Modelbase comes with LFM 2.5 (1.2B) by Liquid AI, which works offline from the first launch, and you can download about 53 more open models, such as Qwen, Gemma, Llama, Phi and DeepSeek R1.

iPhone and iPad with iOS 18 or later, and Macs with Apple silicon and macOS 15 or later. Larger models need more memory: on an older device, start with a small one such as LFM 2.5 (1.2B), which comes with the app.

About 53 open models: Qwen 3.5, Qwen 3 and Qwen 2.5; Gemma 4, Gemma 3 and Gemma 3n; Llama 3.2; Phi 4 Mini; Granite 4.0 and 3.3; Ministral 3; SmolLM 3; MiniCPM 5; DeepSeek R1 (distilled); LFM 2 and LFM 2.5; and vision models such as Qwen 3 VL and SmolVLM 2. LFM 2.5 (1.2B) comes with the app.

MLX is Apple's machine learning framework for Apple silicon. Modelbase uses it to run AI models on the iPhone, iPad and Mac themselves, instead of on a server.

No. We do not collect, receive or store your chats, and Modelbase has no analytics and no tracking. Your chats stay on your device and, if you use iCloud, in your own private iCloud storage, which we cannot access.

Yes. Connect OpenRouter with your own key, or add your own server (any server with an OpenAI-compatible API) in Settings. Its models then appear in the model picker next to the ones on your device.

Yes. It searches with DuckDuckGo, reads the pages, and answers with numbered sources you can open. Deep research gathers many searches and pages into one answer, and live cards show the weather (Open-Meteo), stocks (Yahoo Finance) and places (Apple Maps). You can turn web search off at any time.

Modelbase is available in 15 languages.

In the app, open Settings and choose Get Support: it starts an email with your app version and device, which you can read before sending. Or write to us at support@modelbase.app.
