+## Model Card
+
+### Model Description
+
+This is the official `GigaCheck-Classifier-Multi` model from the `LLMTrace` project. It is a multilingual transformer-based model trained for the **binary classification of text** as either `human` or `ai`.
+
+The model was trained jointly on the English and Russian portions of the `LLMTrace Classification dataset`. It is designed to be a robust baseline for detecting AI-generated content across multiple domains, text lengths and prompt types.
+
+For complete details on the training data, methodology, and evaluation, please refer to our research paper: link(coming soon)
+
+### Intended Use & Limitations
+
+This model is intended for academic research, analysis of AI-generated content, and as a baseline for developing more advanced detection tools.
+
+**Limitations:**
+*   The model's performance may degrade on text generated by LLMs released after its training date (September 2025).
+*   It is not infallible and can produce false positives (flagging human text as AI) and false negatives.
+*   Performance may vary on domains or styles of text not well-represented in the training data.
+
+
+## Evaluation
+
+The model was evaluated on the test split of the `LLMTrace Classification dataset`, which was not seen during training. Performance metrics are reported below:
+
+| Metric                | Value   |
+|-----------------------|---------|
+| F1 Score (AI)         | 98.64   |
+| F1 Score (Human)      | 98.00   |
+| Mean Accuracy         | 98.46   |
+| TPR @ FPR=0.01        | 97.93   |
