OpenZen AI 2B
OpenZen AI 2B R7 analyses photos in current LifeZen versions. Its use in DocZen 1.1 is prepared. Search in HelpZen, MedZen and JobZen does not use a generative AI model.
Availability
| App | Availability | Data processing |
|---|---|---|
| LifeZen | iOS 1.1 · App Store · Publicly available | Android 1.0.3 · Google Play · Publicly available | From iOS 1.1 and Android 1.0.3, LifeZen sends the selected photo, language and, where applicable, location information over an encrypted connection to OpenZen AI 2B on self-managed infrastructure in Germany. Older versions use an external AI service. No account is required. |
| HelpZen | iOS 1.1 · App Store · Publicly available | Android 1.2.0 · Google Play · Publicly available | Search and distance calculations run in a directory on your device. Updates come from OpenZen over HTTPS. iOS uses Apple MapKit; Android uses MapLibre with OpenFreeMap. Map services may receive connection data and the requested map area. Search does not call generative AI. |
| MedZen | iOS 1.4 · App Store · Publicly available | Android 1.1.2 · Google Play · Publicly available | MedZen searches an on-device database and orders results by distance. Updates come from OpenZen over HTTPS. iOS uses Apple MapKit and may offer system translation; Android uses OpenStreetMap-based maps. Location and map services may process connection data. Search and sorting do not need generative AI. |
| DocZen | iOS 1.0 · App Store · Publicly available DocZen 1.1 for iOS and Android is prepared but has not been publicly released. | Published iOS version 1.0 sends selected document content to an external AI service. Processing exclusively in Germany does not apply to that version. Prepared version 1.1 recognises text on the device using Apple Vision or Android ML Kit and sends recognised text, target language and page number over an encrypted connection to OpenZen AI 2B in Germany. Images and PDFs stay on the device in this new architecture. |
| JobZen | iOS 1.2 · App Store · Publicly available JobZen Android 1.2.0 has been submitted to Google for a closed test. Approval is pending. | Search sends the postal code or coordinates, radius, selected KldB codes, employment and language filters, and app language to the JobZen server in Germany. CVs are not processed and people are not assessed by AI. Favourites and settings stay local. iOS uses Apple system features for optional translation; Android uses ML Kit. |
OpenZen AI 2B R7
OpenZen AI refers to the adaptation and self-hosting of a pretrained base model. R7 is based on Gemma 4 E2B and runs with llama.cpp and Vulkan. It is not a model developed entirely from scratch.
On 7 September 2026, the running service reports a context window of 4,096 tokens. An older API alias remains for compatibility. A model name, an operating server and an approved app release are separate facts.
Data processing
OpenZen does not use user submissions to train its own models. DocZen 1.0 and older LifeZen versions use an external AI service, so the notices on external processing also apply to those versions.
The website, directory data and new OpenZen AI services run on self-managed infrastructure in Germany. A self-administered German VPS provides HTTPS access to the Ubuntu server; the internal connection uses Tailscale. DNS is managed through deSEC. The contact mailbox uses Google Gmail.
Apple and Google process store data under their own responsibility. Maps, address lookup, translation SDKs and websites you open may involve other recipients. Running an OpenZen server does not mean that every function operates without external services.
Limits and important information
Automated results can be wrong or incomplete. Meaning errors are known in some DocZen translations. Check names, amounts, deadlines, negations and required actions against the original.
