# StudyApp card writer

The card writer that the StudyApp desktop app downloads. It's Gemma 4 E2B (instruction-tuned), trained with a LoRA
adapter on StudyApp's own tasks, merged, and quantized to Q4_K_M for llama.cpp. It runs locally, entirely offline.

The tasks it's trained on, using the app's own prompts and output formats:

- flashcards for each page of a student's notes
- facts, scenario questions and practice-test questions
- grading a typed answer, and checking the key points of a written one
- chat that answers only from the student's notes, and answers `NOT_FOUND` when the notes don't have the answer

StudyApp runs it with the multi-token-prediction head from
[ggml-org/gemma-4-E2B-it-GGUF](https://huggingface.co/ggml-org/gemma-4-E2B-it-GGUF)
(`mtp-gemma-4-E2B-it-Q8_0.gguf`) for faster generation.

## Training data

There are 618 examples. Each one was written for excerpts of openly licensed textbooks and passed the same checks the
app runs on its own output. 569 were used for training and 49 were held out to measure it.

The excerpts come from these OpenStax textbooks (openstax.org), which are licensed under
[CC BY 4.0](https://creativecommons.org/licenses/by/4.0). They're free to read at openstax.org.
