+# BHKAI: Turkish news category classifier
+
+> **Private repository, for the BültenHub team only.**
+
+BHKAI assigns a category to each incoming story. When it is confident it answers on its own; otherwise the story goes to the AI model.
+
+## Model
+
+**Method:** TF-IDF (300,000 features, min_df 3) with an SGD classifier (alpha 2e-6).
+
+**Version:** `bhkai-20261030`, trained nightly on the home PC and promoted automatically after its exam.
+
+**Training data:** 437,769 stories labelled by the teacher model (`kategori_kaynagi='ai'`). Data cut-off: 2026-10-30 03:24.
+
+## Exam
+
+The exam uses the last 2 days: 749 stories, half of them, split by crc32.
+
+| Threshold | Coverage | Agreement |
+|---|---|---|
+| 0.8 (live) | 0.512 | 0.997 |
+| 0.7 | 0.659 | 0.973 |
+| 0.5 | 0.855 | 0.902 |
+
+The previous live version scored coverage 0.488 and agreement 1.000 at threshold 0.8.
