What TypeSeer is built on
TypeSeer stands on open-source software and open-weight AI models, and we are grateful to their authors. This page is the same attribution notice that ships inside the app, under About TypeSeer → Acknowledgments.
The full licence texts are published here: every licence, in full. A copy of each also ships inside the app, as the licences require.
The AI models
TypeSeer uses Gemma 4 as its default on-device model, downloaded on first use after the user confirms the choice. The base model is © Google; “Gemma” is a trademark of Google LLC, and Digital Llama is not affiliated with, endorsed by, or sponsored by Google.
- Google publishes Gemma 4 itself under the Apache License 2.0.
- The default checkpoint TypeSeer downloads is the MLX conversion
Animateus/gemma-4-E2B-6bit. TypeSeer passes on the Gemma Terms of Use and Google’s Gemma Prohibited Use Policy for that checkpoint, and our Terms require you to comply with that policy: Gemma Terms of Use · Prohibited Use Policy. - TypeSeer also lets you download and run other models from Hugging Face. Each is governed by its own licence, published on that model’s page, and you are responsible for reviewing and complying with it. TypeSeer grants you no rights in third-party models.
